It has been introduced into North America and is widely established.. Overview. The larva of E. tenax is a rat-tailed maggot, which is saprophagous. Physical blockades between lagoons and barns/coops can prevent larvae from migrating to the barns/coops when searching for pupation sites, and will keep the pupating larvae in a non-essential area (Lyon 1995, Day 2008). [7] Males and females occur in roughly equal numbers in summer and autumn, but males are very rare in the spring, when fertilized females come out of hibernation. [6] When male E. tenax of the spring and summer generations stop dispersing, they settle within home ranges which provide them with locations suitable for sheltering, resting, basking, grooming, feeding and mating.
