The only species in the genus Coccobaphes, Coccobaphes frontifer is an unassuming little bug — so unassuming that it doesn’t have a common name beyond “plant bug”, which actually encompasses the whole family, Miridae. Coccobaphes comes from the Greek for “berry colored”.
This is a very small, probably first or second instar, nymph; the adult is of course larger, but also flatter and with more black, looking rather like a milkweed bug.
He/she was so teeny that it was not until I got a look at the full size photo that I realized he/she is missing a back leg!
