A test of the adaptive deme formation hypothesis. Evolutionary Ecology Research, 2006, 8: 1039–1048. The larvae of the black sawfly Tomostethus nigritus (F.) (Hymenoptera: Tenthredinidae, Blennocampinae) and the privet sawfly Macrophya punctumalbum (L.) (Hymenoptera: Tenthredinidae, Tenthredininae) are developing on ash (Fraxinus excelsior). These sawfly species are univoltine. Females of the two species oviposit under the epidermis of leaves. The larvae are, however, solitary and free-feeding leaf chewers. Tomostethus nigritus appears to be monophagous on ash (Lorenz and Kraus, 1957; Mrkva, 1965) and has a haplodiploid breeding system. One female can lay 80–120 eggs, which are placed singly into young leaves (Mrkva, 1965). Larvae develop fairly fast. Gradations of the species are known to defoliate ash populations (Mrkva, 1965). Distribution: Europe, Turkey, Russia, Caucasus, Transcaucasia, North Africa (Medvedev, 1994; Liston, 1995; Lacourt, 1999); Sibero-European. Host Plant: It was observed that the females deposited their eggs in young leaves of Fraxinus excelsior in the first week of May 2000. The emerging larvae feed on the leaves.
