Biological and morphological studies on the parasitoids (Hymenoptera, Ichneumonidae) of Aprosthema tardum (Klug) (Hymenoptera, Argidae, Sterictiphorinae) in Var, southern FranceField surveys at four neighbouring but discrete sites in southern France revealed the presence of five ichneumonid parasitoids of the -feeding sterictiphorine argid sawfly . Four of these parasitoids, , (both Ctenopelmatinae), and (both Tryphoninae), could be identified and, by also incorporating laboratory studies, the developmental biology of each was...
Emergence behaviour of adult Trogus lapidator (Fabricius) (Hymenoptera, Ichneumonidae, Ichneumoninae, Heresiarchini) from pupa of its host Papilio machaon L. (Lepidoptera, Papilionidae), with a comparative overview of emergence of Ichneumonidae from Lepidoptera pupae in EuropeUnusually for Ichneumonidae, Trogus lapidator emerges through a hole in the pupal wing case of its papilionid butterfly host that is made largely by a liquid secretion that softens and disintegrates the host tissue. The mandibles are deployed to help spread the secretion, but only towards the very end of...
