Shield Bug (Pycanum rubens) Nymph, Sumatra Indonesia


This photo was taken in Bengkulu Sumatra Indonesia. This bug is a Pycanum rubens in nymph form. This nymph has redish orange color at the upperside of its thorax and abdomen. There is a white symetrical line across its upperside abdomen and thorax, and grey line along the edge. There are four orange small bulbs near the symetrical line at the abdomen, possibly it is the stink glands which release stink liquid when threatened. The size of this nymph is about 10mm. This nymph is from the family of Tessaratomidae under genus of Pycanum.
