Fly larvae were collected from a northern map turtle (Graptemys geographica) nest in which the eggs failed to hatch. The flies were identified as the seed corn maggot, Delia platura (family Anthomyiidae), a widespread phytophagous or saprophagous species in North America that is unlikely to have been a factor in nest failure. Thus, not all fly larvae encountered within turtle nests are the cause of mortality.
