A. Pekkarinen, PARASITISM OF STYLOPS (STREPSIPTERA, STYLOPIDAE) IN POLYLECTIC AND OLIGOLECTIC ANDRENA HOSTS (HYMENOPTERA, APOIDEA), Entomologica Fennica, 8(2), 1997, pp. 109-111
The taxonomic status of many Stylops species described often on the ba
sis of poor female characters is problematic and host specifity of the
se dubious species is largely unsettled. In Germany and Finland, oligo
lectic Andrena species were not observed to be parasitized more freque
ntly by Stylops than polylectic ones. The result does not support seve
ral coexisting Stylops species with strict host specifity.
