BEES AND WASPSX. violacea male - Sept 1995

Three taxa are particularly conspicuous on Thásos, even to the casual visitor - the carpenter bees Xylocopa spp., the velvet wasps Scolia spp. and the hornets Vespa spp. All three are widespread on the island in summer and are noticeable for their large size. The carpenter bees (chiefly X. iris and X. violacea) are magnificent black bees that make a conspicuous hum as they fly fairly ponderously from flower to flower. They are not known to be aggressive and very rarely sting. The velvet wasps are parasites of chafer grubs (Coleoptera, Scarabaeoidea) and harmless to Man but, as they fly fast and are amongst the biggest Hymenopterans in Europe, they can cause unfounded alarm. Megascolia maculata is one of the largest and is a beautiful insect with golden yellow bands across its dark brown abdomen. It is probably quite common on Thásos, where it parasitises the equally massive larvae of the rhinoceros beetle Oryctes nasicornis, but there are several related species with which it can be mistaken. Hornets are also common in the lowlands and in mid-late summer can be seen patrolling most of the island’s beaches or nesting in the old olive groves. Obviously hornets can be very aggressive if their nest is disturbed but generally they ignore Man (unlike many of the social wasps) and will fly up and down beaches looking for food sources without paying any attention to holidaymakers. Two species, Vespa crabro and V. orientalis, have been reported from Thásos.

The island’s fauna was investigated at the end of June 1942 by N. Atanassov (1965) and his list of records covers 60 species of Aculeate Hymenoptera. The checklist appearing on this website is derived from this paper and is probably in need of revision in light of subsequent taxonomic studies (eg. Ancistrocerus parietum). I am grateful to Řistein Berg for assistance with current nomenclature. Atanassov's paper is in Bulgarian and may offer further information to the reader familiar with that language. Since his paper nothing more appears to have been published on the bees and wasps of Thásos but K.M. Guichard of southern England collected Hymenoptera in the north-east of the island in May 1993. Guichard (1980), dealing with the potter wasps (Eumenidae), reported that "no resident [of Greece] has yet attempted their collection and study". This situation presumably applied in general to all of the solitary bees and wasps (though Mavromoustakis (1958) at least worked on the bees of central Greece), but things have no doubt improved over the past twenty years as several Greek museums and Universities have taken more of an active interest in non-agricultural entomology. Recently, Anagnostopoulos (1999, 2005) has begun to collate information on the bumblebees of Greece, reporting twenty-eight species but others no doubt occur. He maintains a website on Greek bumblebees, although this is entirely in Greek.
