抄録

Astegopteryx styraci forms large coral-like galls on twigs of Styrax obassia. The following facts about its biology were obtained : 1) A. styraci is monoecious on the storax. 2) It produces sterile 2nd-instar soldiers. 3) The soldiers not only defend their colony, but also push honey globules and exuviae out of the gall with their heads. Thus, this species is unquestionably "eusocial" even if we adopt a strict definition of the word.
