For a successful introduction of your chosen species, be sure to provide nectar and pollen. If introducing them into an enclosed space like a cage, simply open the lid as they hatch; if releasing in blooming vegetation, place some honey-water on cotton inside the package before closing it again. Then wait another full day for even more males to emerge – providing plenty of opportunity for instantly taking part in their natural mating ritual!
Eupeodes americanus is shipped as pupae in a moisture-controlled medium. Once all the adults have emerged, sift out the puparia. Successful emergence is demonstrated by an open and hollow puparium. Despite the average insect emergence rate of 90%, up to 10% may remain unexposed.
