“Found in a Tokyo school. My students were keen to identify it.”
Good evening!
Thanks for your submission to Bugs of Japan. The bug you sent is clearly a Stink Bug (kamemushi), but there are several varieties in Japan and they are all a little bit different. Kame-mushi are a little bit special when we say "bugs" because they are actually True Bugs (hemiptera), which also includes cicadas, aphids and bedbugs, and a distinguishing feature is that they have piercing/sucking mouthparts (like a straw) in both their baby (nymph) and adult forms.
The particular Stink Bug you've sent appears to be a "Kimadara Kamemushi" (see comparison photos here https://ameblo.jp/murmecophaga/entry-12618123641.html ), Erthesina fullo. (English name: yellow-spotted stink bug or yellow marmorated stink bug.)
They are found in East and Southeast Asia and eat plant juices! Thanks for your submission and have a good summer!
