MACROLARVIPAROUS REPRODUCTION IN EUPHUMOSIA (DIPTERA: CALLIPHORIDAE)

Abstract

A species of Euphumosia, abundant in Arnhem Land, was found to be macrolarviparous. The ovaries are reduced to two ovarioles each, and only one ovariole ovulates at a time. The larva is retained in utero at least to the end of the 1st instar. The uterine egg and morphological features of the 1st and 2nd instar larvae are described and illustrated. The breeding medium remains unknown, but possibilities are discussed.
