This family of flies comprises some of the largest flies in North America. Some of the species can get as long as 60mm (2 inches). Mydas Flies are harmless despite sometimes being mistaken for wasps.
Females lay fertilized eggs in the ground. Larvae can be found in forests near rotting and dead wood. It eats other bugs and grubs that it finds in the dirt, including June Bug larvae. Eventually, they pupate in small chambers they create in the soil and emerge as flying adults.
Adults are seen in virtually everywhere (parks, garden, meadows, open lots, forests, etc.). They feed on other insects and caterpillars, including flies of other species. They are very good at flying, though it may not appear to be the case at first glance. They tend to look a bit clumsy in flight. They are most active in the summer months.
