Abstract
The tropical paper wasp, Ropalidia (Icariola) fasciata (F.), nests
on leaves of gramineous plants (Miscanthus sinensis Andus. and sugarcane) in
Okinawa, where there are frequent, strong typhoons. In Taiwan and Java,
where the effects of typhoons are less severe, most nests are on tree twigs. A
similar difference is seen in nests of Ropalidia (I.) marginata (Lepeletier) in the
Northern Mariana Islands and in India. Okinawan R. fasciata also exhibits
quite flexible social behavior, low frequency of intranidal dominance behavior,
construction of satellite and multiple-comb nests, absconding swarming, and
initiation and development of nests in late autumn. Study of the divergence of
social habits in eusocial wasps on Pacific Islands will enhance our understanding
of social evolution in insects.
