Brachyplatys

I have moved to http://keicmacro.blogspot.com/

I do not have any other shots of this shield bug. It flew away after the first shot; at a garden in Bandar Puteri Puchong, Selangor, Malaysia. The size of this bug is roughly 4 mm long.

Thanks to Paride Dioli for helping me identify this bug.

Family: Plataspididae (often misspelled Plataspidae) are a family of shield bugs native to the Eastern Hemisphere: shining, oval hempteran insects in the superfamily Pentatomoidea - Paride Dioli

Further search found that this shield bug falls under the genus Brachyplatys, species Brachyplatys cf. subaenus. The head of the male and female are similar, black glossy body, with yellow sides at the leading edge and the side edge of the head and pronotum but may differ from individual to individual, some individuals are all black.

[Edit:]

I returned to the same site and spotted it again (picture below).

Tachinidae

This photography was taken at the foot hill of Bukit Larut (Maxwell Hill), Taiping, Perak, Malaysia in the late evening.

Despite the dim environment, the fly seemed sensitive to my movement. The abdomen is slightly transparent. According to Chris Raper, this looks like subfamily dexiinae.

The Crazy Black Ant (Paratrechina longicornis)

I have moved to http://keicmacro.blogspot.com/

They are called crazy ants due to their erratic but quick movements, like we call somebody crazy when he is driving with speed with unpredictable directions. I personally find this type of ant extremely difficult to photograph because it doesn't stay put, unless when they're eating. I noticed when the ant is surveying an area, it often return to the some spots for a short duration. I make use of this pattern by pre-focusing on that spot and snap it when it stops there. Here's the shot:

The crazy black ant is not entirely black, but with bluish patches. Their quick reflex and response to objects around them is astonishing!

Banded Phintella (Phintella vittata)

I have moved to http://keicmacro.blogspot.com/

According to a research led by Assoc Prof Li Daiqin, Department of Biological Sciences, NUS, the phintella vittata have the ability to see ultraviolet B rays (UVB), Current Biology, Volume 18, Issue 9, 6th May 2008 

Ultraviolet B rays has shorter wavelength compared to ultraviolet A rays. Both rays penetrate the Earth's atmosphere and are harmful to human skin.

I was very lucky indeed to meet one such jumping spider near home. It's a male. The picture below is the best shot I had.

The subject is extremely difficult to photograph because it is hyperactive and has a very reflective body. It jumps from leave to leave very quickly. When view with the naked eye, the colours on its body do not look like the photograph above, but bright shiny blue. It's a tiny spider, perhaps between 3 - 4 mm body length. It is an extremely beautiful spider.

Another shot of it making web between two leafs:

With fangs slightly visible:

As you can see in the shot below, it's body reflective surface is not easy to shoot. During shooting, it jumps onto your flash light diffuser very quickly as soon as it notices it. You can place the diffuser further, however,  reflective subject always appears ugly when lights bounce back to the camera lens from that flash angle.

Thanks for visiting !

Ants & Aphids

I have moved to http://keicmacro.blogspot.com/

Aphids invaded parts of my lawn, due to uncontrolled growth of weeds. Before mowing my lawn, I took the opportunity to observe its activities and capture some photographs.

Fig.1 A group of aphids (young and adults) on the stem of grass

As I was observing, I noticed black spiny ants (polyrhachis sp.) were climbing up and down on these grass where the aphids were. I did not know what they were doing, but noticed the ants were using its antennas to touch the aphids. In some occasion, it pushed the aphids so hard that the aphids were partly lifted off the grass.

Fig 2. A black spiny ant rubbing aphids with its antenna

As ants usually attack or eat other insects, I was surprised it did not attack the aphids. After googling the web, I realised ants have good relationship with aphids. They depend on each other. The ants want the honey the aphids could supply. In return, the aphids are protected from their predators.

Other than the black spiny ants, there were another species of ant, tetramonium hispidum, looking for honey from the aphids. Despite its smaller size, the red ants dominates. Black ants were seen being chased away.

Fig 5. Black spiny ant witnessed the birth of a young aphids

Unlike other insects, this species of aphids reproduce asexually where the females give birth to offspring without mating or laying eggs.

Fig 7. Winged aphids

Most adult do not have wings. However, when the population is high, female aphids produce wing capable aphids where the wing will grow as they are matured. This enable them to disperse to other areas for food.

Where there are aphids, there are predators. Usually the predators are a larvae of beetles.

Pycanum Rubens Nymph

I have moved to http://keicmacro.blogspot.com/

The following nymph of stink bug (shield bug), pycanum rubens, was found at the Kota Damansara Forest Reserve, Petaling Jaya, Malaysia. It is easily spotted due to the bright orange colour. The nypmh is not active and can be photographed easily.
