This flesh fly was associated with a Yellow Pitcherplant (Sarracenia flava) at Holly Shelter Game Lands in eastern North Carolina (USA), 19 April 2008. Apparently certain flesh flies breed IN the pitcher, which would be a deadly environment for most insect larvae. This might be a Fletcherimyia or a Sarcophaga.

This flesh fly was apparently defending a territory around a Yellow Pitcherplant (Sarracenia flava) at the VOA site in Beaufort County NC (USA). I have seen this once before, also in the North Carolina Coastal Plain. Apparently certain flesh flies breed in the pitcher, which would be a deadly environment for most insect larvae. This might be a Fletcherimyia--see below. (Some Sarcophaga also breed in the pitcherplants--I do not know how to tell them apart.)

"Living within the pitchers of almost all the species of pitcher plants in the southeastern United States (Sarracenia spp.) are larvae of some extremely specialized flesh flies (Diptera: Sarcophagidae)....
The sarcophagid genus Fletcherimyia has 5 described species, all of which develop only within the pitchers of pitcher plants. There is also one species within the genus Sarcophaga...that spends its larval portion of its life cycle within pitcher plant pitchers. The larvae feed on the decaying insects trapped by the plant. While Sarcophaga sarraceniae appears to be a generalist, being reared from a wide variety of Sarracenia species, many of the Fletcherimyia are much more intimately associated with few (often one) species of pitcher plant."
