Photo by Drees. Larvae pupate close to the soil surface and emerge as adults in about a week. Development from egg to adult can occur in about 21 days, but takes longer during colder winter months. They can occur year-round and may be locally abundant at certain times of the year, such as spring and fall, when conditions are favorable for their development. Larvae develop in a variety of habitats such as decaying plant and animal matter and plant rootlets, particularly in freshly disturbed, well drained and aerated sandy soils.
Female flies attack animals while males are attracted to flowers.
Adult females can be collected with a fine-mesh aerial net by swinging it around ones head while walking through infested areas. For additional information, contact your local Texas extension service agent, or search for other state extension service offices.
