Termite Infestation!

This afternoon, I got a text from my daughter that her boyfriend's sister's room had been infested by termites! Not surprisingly, without a pause, she asked if I would like to have some!

Of course, I never say "No" to this kind of request. Just to be on the safe side, I asked her to get a few more, plus the wood that they had been feeding on.

"It is going to be an exciting evening", I thought.

Yes, indeed. Here are some photos of the cute termites, both the Coptotermes gestroi soldiers as well as workers. The termites are about 3.0mm long. Do enjoy, if you like termites!

The little termites are busy fellows, as they explore their new facility. Thanks to the safe method of containing them, the termites arrived at my home in good health.


Here, a worker (creamy-white) is seen "kissing" a fellow soldier. Actually, not. It is trying to move to the right when the soldier termite makes a left turn. When you are looking through a macro lens, you tend to see them as individuals, rather than a mass of termites.


The container that I used to keep them toppled over and some died as a result. I also did a few checks - non escaped! A soldier is seen here checking out a dead comrade. On the right is a worker.

Side view of the same soldier. This time it has decided that it is safe to make a down-hill trip from the original wood that it came from. The bottom-right object at the foreground is a grain of sand.


You can clearly see the fontanelle on the forehead of the soldier. A white latex-like droplet is often secreted from the fontanelle when challenged. An article from [https://taxo4254.wikispaces.com/Coptotermes+gestroi] mentions that the defensive secretion can represent up to almost 40% of the body weight!

A gathering of friends.



Two soldiers communicating with each other. What information could they be passing on?


Here, a soldier has a grain of sand stuck to its forehead, as a result of the defensive secretion earlier on. Notice the "glue-like" thing on its right pincer? The sticky stuff is supposed to act as a buffer zone between the soldiers and other attackers. Ants are their enemies and this sticky stuff will actually hold an unfortunate ant at bay while another soldier kills it off.


Finally, a sentinel standing guard.

American Cockroach - Once In A While

This evening an adult cockroach paid our home a visit. He was spotted flying into the boys' room by my daughter, and in a dramatic sort of way. You know, cockroaches don't fly nicely - they flap scarily all around, like trying to find someone's head to land. Very obviously, lots of screaming were heard.

Nevertheless, my elder son - who is currently serving in the NDU (Naval Diving Unit, Singapore) took care of it and presented me with the captured "periplaneta americana", an American cockroach. We do not get cockroaches often, either from the wild or internal-breeding as our home is well-kept by all of us.

Here are some shots of the insect that is widely considered as a pest, in all senses. Hope you will like it, at least the photos.


This particular, adventurous cockroach is about 45mm in length. I placed it in my photo-box that I made for insect photography (especially those that sneak into my home). Here, it is looking at me while I was adjusting my macro lens.


Although, it is considered as a pest, this cockroach certainly has a well-formed and neat body. A close-up view certainly gives us a better feel of its external structure. Just look at the lower segment of the neck! Like a set of goatee!


From the moment it was handed to me, this cockroach has never stopped cleaning itself. I observed that it can even clean its hind legs, up to the "thigh-joint". Now, that is a good show of flexibility, in spite of its longish body.


The cockroach is resting. Yes, it does that once in a while and then when it is done, it looks up and starts checking out the surrounding for a way to escape. After spending a few hours with him, it seems like we had become friends.

It is from here that we know this American cockroach is a male adult. Here you can see the presence of the cerci and styli. The cerci are the two longer (larger) appendages. The styli are the pair of smaller and delicate appendages appearing at the lower abdominal segment.
