Morning walks and runs around the Zabeel Park, Dubai is truly an awesome time. As the cool morning breeze was blowing, I was fascinated to see lovely ladies immersed in yellow blossom, oops.. I mean lovely ladybird beetles immersed in yellow blossoms. Looking upon the distinct 6 darkened markings on its elytra, I have encountered the Six Spotted Zigzag Ladybird Beetles. 

The Six Spotted Zigzag Lady Bird Beetle, Cheilomenes sexmaculata 
(COLEPTERA: COCCINELIDAE)
The Six Spotted Zigzag Ladybird beetles is a well known and wide spread species of ladybird beetle (coccinellids). These beetles are 3-4mm long, yellow to canary yellow in color with 6 distinct dark markings on its elytra.  

DISTRIBUTION OF Six Spotted Zigzag Lady Bird Beetles
These ladybirds are reported to be present in the tropical and subtropical regions of Asia, particularly in India, Indonesia, Pakistan, Malaysia, Philippines and Japan. They are present in the Middle East Region and also reported in France, the United Kingdom, South Africa and Australia. 

BIODYNAMICS NOTES
These ladybirds are voracious predator! They are known  as relentless hunters in the insect world!
They hunt and feed upon whiteflies, aphids, scale insects and diaspids, 
There food insects are mainly agricultural insect pests, which makes these ladybirds important biological control agents!

By the way you might have encountered the term "ladybug." The ladybugs are not true bugs (from the insect order Hemiptera) but they belong to the coccinellid family of beetles (Coleoptera)

These beetles DO NOT feed and damage plants and crops. They DO NOT bite and attack humans. 

As stated, these ladybird beetles act as BIOLOGICAL CONTROL agents against insect pests of crops. If possible, DO NOT spray the plants or locations where you see these little insect hunters. Let these ladies continue on their voracious hunting spree!

Ladybird beetles maybe small but they have the tenacity of any large size predator whenever they are roaming their plants landscape. 

Awesome Creature! AWESOME CREATOR!

Locate the longhorn beetle in the vegetation

It was a windy weekend morning and as I was strolling around the walk-way around the Zabeel Park,  Dubai, I stumbled upon a large, dark brown beetle clinging on the pod of the landscape plant. This was my first time to see a live longhorned or longicorn beetle in the UAE and upon my research about it, I get to know that what I encountered was the date palm pest, Longhorn Date Palm Beetle or Borer, Jebusaea hammerschmidti.  

LONGHORN DATE PALM BEETLE, Jebusaea hammerschmidti 
(COLEOPTERA: CERAMBYCIDAE)  
Beetles from the family CERAMBYCIDAE are characterized by their extremely long antennae which can be longer or have the same length as its body. 

The Longhorn Date Palm Beetle or Longhorn Date Palm Borer is a well-known member of the longhorn beetles family as it is listed as an important pest of date palms (Pheonix dactylifera). 

The adult beetles are dark brown color, with females 30-45mm long and the males 21-31mm.

The larvae are creamy white, legless, the first 2 thoracic segments of the body are broader than the rest, the body tapers up to its posterior end. 

DISTRIBUTION of the LONGHORN DATE PALM BORER
This longicorn is reported to be an important pest of date palms in the Middle East, North Africa and India. 

BIODYNAMIC NOTES
The eggs are laid on the fronds of the date palm, wherein they dig into green frond base for months and they they bore their way into the trunk. They spend their whole larval and pupal development stage inside the trunk. 

It prefers to infest old, neglected date palms but it can also attack young and healthy trees. 

The attack of the longhorn date palm borer greatly affects the date palm lifespan, its yield and the quality of the palm wood. 

For the control of these longhorn beetles in Date Palms follow label recommendations of approved and registered Agricultural Pesticides.

I have always keen a fascination for beetles, especially the longicorns. Their relatively large size, the thick sclerotized body armor and the long pair of antennae are truly awesome to observe and document. 

I hope to get more awesome beetle encounters.

I know these longhorn beetles are agricultural pest, but despite their potential threat to date palms,  they still look so awesome!

Awesome creature! Awesome CREATOR!

A Robber Fly Encounter at the Desert Area Adjacent Dubai Academic City

Female Robber flies are ferocious hunters

This is my 3rd live encounter with Robber flies in the desert

I was searching for desert dwelling beetles during my early morning hike, when a large fly buzzed passed me and then landed on the sand. Its large and piercing blue-green eyes immediately got my attention. It was a female Robber fly setting up herself for another flight prowl in search for prey. This will be my 3rd encounter with the ASILIDAE here in the UAE. I had two sightings on  the trails in Maleha, Sharjah and this will be my first in Dubai. 

By the way ROBBER FLIES are also known as ASSASSIN FLIES! 

FOR MORE INFO on Robber flies check out my Feb 17, 2022 and July 03, 2021 articles.

The giant golden orb weaver 

It was during our early morning hike at the trail of Mt. Makiling in Los Banos, Laguna, that my daughter, Odette spotted this awesome giant golden orb weaver. Located just on the side of the hiking path, it has strategically laid out its large silken web across the shrubs and tree branches. The large female spider was in the middle of the web, patiently waiting to snare potential prey. As I was getting closer to the web, the lady spider began to shake her web vigorously, trying to distract me as she moves away. I was not distracted, I was more attracted to observe this lady giant spider!

GIANT GOLDEN ORB WEAVER, Nephila pilipes (ARANEAE: ARANEIDAE)

The giant golden orb weaver, Nephila pilipes is one of the largest orb weaving spiders species in the world. In terms of body size, it it second to the recently discovered N. komaci. 

Sexual dimorphism is very evident in spiders, particularly with this species. Female N. pilipes are much larger reaching a body size of 30-50mm (gigantism) while the males are very small with a body length of 5-6mm (dwarfism). Females are mostly black, yellow-brown with golden stripes. The back (tergum) is dark brown covered with dense hairs. Eyes appear in rows which bulge towards its rear. The bottom size of its abdomen (plastron) is mostly black and brown. Legs are very long with, black with yellow. There are no hairs found on the female spiders legs.  Male N. pilipes are 4-10 times smaller than the females. These are mainly brown to reddish brown in color. Their front eyes are larger than their rear eyes. The light brown legs possess hairs. 

DISTRIBUTION of GIANT GOLDEN ORB WEAVER SPIDER 

These giant spiders are found in tropical forest habitats of South Asia (Sri Lanka, Nepal, India), Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Singapore, Vietnam and the Philippines). They are also reported in China, Japan, Papua New Guinea and Australia. 

BIODYNAMICS NOTES

They produced large, orb like structures, composed of elastic, golden silk reaching 0.5-1.0 meter in diameter. The spider web strands are reported to be as strong and durable as kevlar! 

The hub of the spider is usually on the top of the web while it does most of its capturing of prey on the lower parts. As a predator, it employs an adaptive strategy it capturing its prey. Small captures are caught directly, removed from the web and consumed. For larger prey, venom is injected and the spider awaits for the victim to die (truly ferocious!)

N. pilipes are selective in the type of insects that they consumed. They feed mainly on flies, beetles, locust, moths and cicadas.  When other non preferred insects are captured in their web, they remove specific insects that secrete unpalatable compounds like vespid wasps and the alates (reproductives) of ants. Reports have also been made that these giant spiders can feed upon birds and bats captured on their strong web!

These spiders are observed to make food reserve caches during time of plentiful prey to enable them to deal with food shortages. When lots of prey is available, they wrap these surplus food in silk and store these in the hub section of their web. Ready made insect take out food!  

For protection against predation from birds, the spiders stays mainly on their web day and night and build a "barrier network of durable threads" on one or both sides of the web. They also vigorously shake their web to distract and also allow them to move away. 

It is important to note that these giant golden orb weaver spiders are NON AGGRESSIVE and they will not usually bite humans. In cases that you encounter their bite, this can cause muscle pain and tightness. 

A simple request, if you see a spider on its natural habitat, please don't kill it. Let is stay on its golden web. It means you no harm! It is there mainly as GENERALIST insect predator, doing its part in the natural balance of life!

It was truly an awesome encounter with this giant lady spider in the hiking trails of Mt Makiling!

An Awesome Encounter with the Eagles of the Philippine Eagle Center in Davao City

A truly awesome bird - the Philippine Eagle

The Philippine Eagle is considered the largest of the extant eagles in the world

They are also called the Monkey-eating Eagle and the Great Philippine Eagle

These raptors are the apex predators of the forest

The Philippine Eagle Center in Davao is home to these captive birds

"Mindanao" is going to be 21 years old soon

"Sinag" (ray of light) a captive-bred eagle is going to turn 7

"Marikit" (Pretty or Lovely) is a lady eagle that truly lives up to her name

My three lovely ("Marikit") ladies gazing at Marikit the Eagle 

Can you spot "Kaibigan" (Friend) in this enclosure?

Kaibigan - a 23 year old female on her make shift nest 

Showing off its top form - truly awesome!

Contemplating about the future - hopefully it will be bright for these Eagles

Awesome work and effort, Philippine Eagle Center, Davao City!

It was during my recent holiday, that our family journeyed south to explore and enjoy the beauty and wonders of Davao City, Mindanao, Philippines. As a naturalist-explorer-adventurer, one of the highlights of trip was our visit to the Philippine Eagle Center. This place is truly awesome, it simulates a rainforest environment, complete with lush greenery, tall trees and streams. There are also lots of butterflies, dragonflies and other bugs that also caught my fancy. This conservation-education-breeding center is home to 36 eagles and other raptor birds, mammals and even 2 large estuarine crocodiles! Truly an awesome place to explore and observed these awesome birds up close!  

The Philippine Eagle, Pithecophaga jeffreyi (AVES: ACCIPITRIDAE)
The Philippine Eagle bears a nape that is adorned with long, brown feathers, that exhibits a shaggy, mane-like crest. It has a dark face, creamy-brown nape and crown. Its back is wholly dark brown while the underside and underwings are white. It possessed yellow-colored heavy legs, equipped with large, powerful and dark claws and the distinguished large, high-arched and deep bluish gray beak. The piercing eyes of these apex predators are blue-gray. Adult Philippine Eagles measure 2.82 to 3.35 feet (86 to 102cm) long with a weight of 8.9 to 17.6 lbs (4.04 to 8kg). Average length was reported to be 3ft 1in (95cm) for males and 3ft5in (105cm) for females.  

The Philippine Eagle is considered as the largest of the extant eagles in the world, in terms of length and wing surface area. Wingspan is measured at 6ft to 7ft3in (184 to 220cm) and the wing chord length at 22.6-24.2 in (57.4-61.4cm). Only the Stellar Sea Eagle and Harpy Eagle are larger in terms of weight and bulk. 

Distribution of the Philippine Eagle
The Philippine Eagle is endemic to the forests of the Philippines and found mainly in the major islands of eastern Luzon, Samar, Leyte and Mindanao.  

Biodynamics Notes
A complete breeding cycle of the Philippine Eagle last for up to two years. A female becomes sexually mature at 5 years while the male takes 7 years. Similar to most eagle species, the Philippine Eagle is monogamous. Once the birds paired, the couple will stay together for the rest of their lives (now that's what you call bird commitment).
The average life span of the Philippine Eagle in the wild is 30 to 60 years. A captive bird at the Philippine Eagle Center in Davao City was reported to live up to 46 years.    
The Philippine Eagle is the most dominant predator in its Philippine forest habitat. Recent studies conducted in Davao City revealed the nearest distance between mating pairs can cover 13km (8.1mi). That is still considerable forest size, which makes these huge birds extremely vulnerable to deforestation. As apex predator of the forests, listed among its prey are the fruit bats, rats, tree squirrels, flying lemurs, flying foxes, the giant cloud rats, large snakes and lizards, large birds like owls and hornbills and also monkeys, 
I remember a story my youngest Brother, John Louie, shared with me regarding their encounter with these raptors up on the high slopes of Mt. Banahaw in Luzon. He told me that when they had a sighting of an eagle, they hurried to hide in their tents to avoid being spotted and for these young mountaineers to be mis-identified as monkeys moving across the mountain foliage. Well I don't blame them for hiding in fear, this eagle was not formerly called the Monkey-eating Eagle for nothing! 

The Philippine Eagle Center in Davao City is doing such a noble and excellent work in education, research, breeding and conservation of these majestic birds. I truly had an awesome time during our visit.

The Philippine Eagle is truly an awesome bird of prey! May it continually soar in the sky above the forests of the Philippines.  Lets protect it and conserve its natural forest habitats.           

Awesome creatures. AWESOME CREATOR!

Flapping its wings and displaying the vibrant colors and patterns 

Prominently black pattern with the red tornal spots of the upper wings

It was a lovely cloudy morning, in our home garden in Los Banos, Laguna, Philippines, my lovely wife, Elmira, encountered a stout, pale green pupal case on the wall adjacent her Calamnsi (Philippine Lime) shrub. I told her that it is the chrysalis of the Citrus Swallowtail Butterfly and encourage her to wait for the butterfly to emerge. After 4 days, early morning, we were overjoyed to see a newly emerged beauty, as if it was still waiting for us to showcase its radiance and capture amazing snapshots. After a brief moment of flapping and folding its wings, the butterfly briskly flew around and out our garden. It was a beautiful morning at home.     

CITRUS SWALLOWTAILS Papilio demoleus (LEPIDOPTERA: Papilionidae)
Citrus swallowtail or the lime swallowtail are large papilionid butterflies. The adults have a wingspan of 80-100mm. The upper forewing is mostly black with its outer margins bearing a series of yellow spots. The upper hindwings has a red tornal spot  and a discal black band with yellow scales. The underside of its wings is pale yellow with black areas. Unlike most swallowtail species, wings lack the prominent tail. 
The pupa or chrysalis is stout, pale green and 30 mm long. 
Females lay eggs singly on the edges of the host plant leaves. The egg hatch in six day and the larva undergo 5 instars. Depending on temperature conditions a whole generation can take 29-59 days.  

DISTRIBUTION of CITRUS SWALLOWTAILS
The Citrus Swallowtail are widespread butterflies present in citrus shrubs and other host plants in tropical and subtropical regions of Southern Asia, from Saudi Arabia, the United Arab Emirates, Iran, to Southern China, Taiwan, Japan, Malaysia. Indonesia, the Philippines, New Guinea, Australia, Dominican Republic, Puerto Rico, Florida in the USA, Jamaica.  

BIODYNAMICS NOTES
Citrus Swallowtail larvae are voracious defoliators of citrus shrubs. They consume large portions of the young leaf flushes. In citrus nurseries they are considered a major pests. 

In our home garden these defoliators are able to take a grand share of the leaves of our Calamansi shrub. Thankfully our shrubs are able to recover and grow more leaves. More available foliage for these awesomely beautiful butterflies. May they frequently visit our home garden and fill the space with their innate beauty.

Awesome creatures. AWESOME CREATOR!

A Fine Summer Morning Encounter with Carpenter Bees at the Zabeel Park, Dubai

A Canary Carpenter Bee getting busy on a summer morning

As the summer breeze is blowing you can here this Black Carpenter Bee buzzing 

A female going for a a soft, floral landing

The blue compound eyes truly got my attention

Fully engorged, fully engaged

Hide and Seek: Can you spot the Carpenter Bee?

CB you are clear for landing

Hovering in a sea of bright yellow blossoms

Jogging-Walking Pathway of Zabeel Park, Dubai: Summer morning, the sun is up, it was truly windy all across the Park. As I was doing my walking rounds, I found patches of bright yellow blossoms along the pathway. Close examination of these blossoms revealed numerous Carpenter Bees truly engaged in their pollination endeavors. Flying, hovering, landing, moving, gathering in a floral sea of yellow, these Carpenter Bees, were a sight to behold!
          
The Black Carpenter Bees, Xylocopa spp, and Canary Carpenter Bees, Xylocopa pubescens (APIDAE)
The Black Carpenter Bees (Xylocopa spp.) are large and robust bees, with a shiny black, metallic sheen. Its thorax is covered with black hair and the dorsal side of its abdomen is glossy and bare. Females have a black head while the males have a white marking on its head and a dense bunch of hair on its hind legs. Their wings are shiny black. Females can grow up to 40mm. 

The Canary Carpenter Bees, Xylocopa pubescens are also large and robust bees. The females can grow up to 25mm and the males up to 18mm. The females have mainly black abdomen and the thorax is covered with a yellow hair. The males are more covered in yellow hair. Females have black compound eyes while the males have greehish-yellow eyes. Wings of females are shiny black and the male wings are speckled and lighter in color.  

Biodynamics Notes
The Carpenter Bees got its name due to its nesting behavior, where all species burrow into wood,  bamboo or any hard plant materials. The fertilized females bore into the wood, excavates a tunnel to lay eggs. They do not eat wood. During nest construction, they discard the pieces of wood or re-use these pieces to make partitions for their cells. 

For a more detailed discussion on the Carpenter Bee Biodynamics and Distribution, please check out my feature last July 06, 2021 (A Carpenter Bee Encounter at the Warzan Desert in Dubai).  

The Carpenter Bees may be large, distracting, and the loud buzzing sound is quite disturbing but take note that the males are harmless and they do not have a stinger. The females are capable of stinging but are very docile and will not sting unless directly handled or provoked. 

These robust bees have short mouth parts and are major pollinators of numerous flowering plants.

Dear PMPs if they are not a direct threat to you and to your customers, please DO NOT KILL THESE BEES! Kindly allow them to pollinate the beautiful flowers and gather the needed nectar.

Observing these robust bees as they forage on the patches of yellow blossoms around the Zabeel Park, in the warmth of the early morning sun, was quite an awesome treat!

Awesome creatures! Awesome CREATOR!
