HYMENOPTERA, Tenthredinidae (Tenthredinoidea) -- <Images>
& <Juveniles> Please refer also
to the following links for details on this group: Tenthredinidae = Link 1 The predaceous habit has developed in adults of a
number of species (Clausen 1940/1962).
Adults of Tenthredella nigropicta Smith feed extensively on
the larvae and pupae of chrysomelid beetles of genera Melasoma and Plagiodera
in Japan, eating 2-3 full grown larvae daily (K. Iwata cited by Clausen,
1940). Hobby (1932) listed different
species and their prey in England, including Tenthredo, Tenthredella,
and Rhogogaster, their prey comprised
mainly of small Diptera and sawflies.
Flies that frequent flowers seem favored, probably because of an ease
of capture during feeding. Species in
genera Macrophya, Tenthredopsis, and Taxonus have also been observed to be
predaceous. In most cases only
females are predatory. References: Please refer to <biology.ref.htm>,
