Green jewel bugs

If you are the kind of person who looks closely at leaves and trees now and then, it won’t be long before you start seeing the aptly named green jewel bug everywhere. It is widely spread across continental Asia. I see it in gardens all the time. So I was not going to post the featured photo.

But there is something interesting about these true bugs: apparently they are not found in the islands of Indonesia, Philippines, Sri Lanka and Japan. The photo you see above was taken in South Andaman near the Mount Harriet National Park. I wanted to put on record the fact that there are islands where it can now be seen. Whether it flew or was carried there by winds, or was introduced inadvertently by humans is unclear. Interestingly, the upper parts of its legs are orange, whereas the ones I’ve seen before all had green or black legs. There seems to be quite a bit of variation in form, size, and colour in this species, so I’m not sure how significant this colouration is.

It is fairly easy to photograph these, and other, metallic shield bugs. They are easily seen on upper surfaces of leaves, branches and flowers. They do not hide the moment they spot the huge eye of a camera looking at them. Maybe this has something to do with the fact that they can release bad-smelling chemicals when attacked, and therefore are not good things for predators to eat.
