Drosophila spp., seasonal abundances, lowland forest

Abstract

We have studied the seasonal abundances of Drosophila species collected from a lowland forest community in northeastern Iowa. Eleven species were collected of which six were collected in appreciable numbers (over 20 individuals). One species, D. affinis, is dominant until early summer when it virtually disappears and a second species, D. tripunctata, becomes dominant. Two other species, D. falleni and D. robusta, also are very common early in the year and collected much less frequently later. It is hypothesized that temperature is a critical factor in determining these seasonal patterns.
