Abstract
Sticky panels (7 colored, 1 clear) were placed at 2 heights in a Connecticut forest in the spring and summer of 1979. Of the tachinids captured, 9 species or species groups were analyzed to see whether trap catches could be related to the egg laying habits of each species. Macrotype egg depositors ( Parasetigena silvestris (Robineau-Desvoidy), Tachinomyia sp., and possibly Oswaldia sp.) were caught preferentially on white, yellow, and blue panels placed 15 m above the ground in trees. Males greatly outnumbered females. Microtype egg depositors ( Patelloa silvatica (Aldrich and Webber), Gonia sagax Townsend), on the other hand, were caught on panels placed 0.6 m above the ground as abundantly as on those 15 m high and preferred yellow and white panels. Males outnumbered females, but not to the same extent as for the macrotype egg depositors. Comparisons between other tachinid species groups were inconsistent.
