A bright green spot flew in front of me and landed on a tree which gives a characteristic redolence to this time of transition between sharad and hemant, the night-blooming jasmine (Nyctanthes arbor-tristis, parijat in Hindi and Odia, shiuli in Bengali, xewali in Assamese). When it landed I could see that the shiny green spot was a green jewel bug (Chrysocoris stollii, aka the lychee shield bug). I haven’t identified any of the other 450 jewel bugs, so I can’t be certain. But this had characteristic markings, and the colour, of what I was told was the C. stollii.
Of course one can do better these days, I realized as soon as I wrote that sentence. A little search with the help of google mamu told me quickly that the markings on the back were not of the C. pulchellus or C. patricius. I’m glad I did that check, because I found that in 2017 I’d posted misidentified photos; those smaller bugs were probably C. patricius. I’m also pretty certain now that this is not the C. purpureus, since that should be purple, as its name suggests. Could it be the C. hahn? The pictures I came across are confused, and I can’t figure out whether this is different. But let me go with C. stollii, for now, especially since it is supposed to be the most abundant of jewel bugs in India.
So what do I know about it? It is a bug, not a beetle, although the green shield could mislead you. If you look carefully, you’ll see that there is no mid-line parting on its shield; a beetle will have a divided back. You can also try to distinguish them by counting the number of segments on legs and antennae. Since it drinks sap from plants, it is considered a pest. My fund of knowledge runs out pretty fast. I must look for more bugs, this is a season for insects anyway.
