Asteiidae Flies of Hawai'i

Asteiidae is a very small family of flies, consisting of about 130 described species from 10 widespread genera. Because of their small size as a family, specimens are rarely collected in the wild. Flies are 1 to 3 millimeters in length, are relatively thin-bodied and exhibit a yellow-black or other dark colored hue. Unlike females, males have distinct frontal stripes. Adults from some species exhibit host preference, while others can be found on a range of hosts and substrates, from flowers to window screens. The larval biology of this family is still a mystery but past research suggests that the larvae may scavenge and feed during the feeding of other insects. Another notable characteristic displayed by Asteiidae flies is that they are acalyptrate, or are not blood-feeders.
