Abstract

The eggs of Euphranta connexa (Fabricius) and Scambus brevicornis (Gravenhorst) are described for the first time. Although the 3rd instar larva of E. connexa has briefly been described from Czechoslovakia, Swedish specimens are shorter, have fewer tubules in the anterior respiratory organ and the interspiracular bristles of the posterior respiratory organ look different. SEM studies of the 3rd instar larva also revealed ultrastructural characters of taxonomic significance. This is clearly shown in comparisons made with other tephritid species.
