Abstract:
The tachinid species Ormia Dominicana, Ormia lineifrons,
and Sitophaga aurigera were observed to aggregate
atop 2 towers in central Florida shortly after sunset.
The activity period for each species was brief, and
that of 0. dominicana was temporally separated from
that of S. aurigera. Aggregations occasionally exceeded
100 individuals of a species and were predominantly composed of males. Although no matings were seen, it is
presumed that this behavior facilitates mating. The behavior
of these flies was typical of insects at a waiting
station. Eucelatoria rubentis and the anthomyiids Pegomyia
affinis and Pegomyia gopheri were occasionally collected
from the towers.
