Gaining
a Knowledge of Therevid Bioecology
A
number of ecology studies of stiletto flies have been initiated.
Power's thesis on spatial and temporal
distributions of Therevidae in southeast Queensland represents
one of the most extensive and intensive quantitative surveys of
Therevidae yet conducted. We now have a much greater knowledge of
the form of the therevid bioscape in southeastern Queensland.

Namib
Desert, Namibia

A
year-long sampling of therevids along the Kuiseb
River of the Namib Desert, Namibia, has shed considerable
light on the flight phenologies of the 4 species that were captured.
Yet another study at Sedgewick State Park near Santa Barbara,
California, is providing altitudinal richness and flight phenologies
of the stiletto flies. |
A
similar study, undertaken in the central foothills of Chile has
provided an excellent account of the timing, relative abundance,
and species richness of therevids in that part of the world. An
intensive study of the coastal dunes of
central California revealed habitat boundaries of 5 stiletto
fly species inhabiting that dune system.
