Goldenrod Gall Fly Life-Cycle. The goldenrod gall fly (Eurosta solidaginis) is a common and widely distributed insect found coast to coast in the central part of North America. The adult flies emerge from their galls in late spring.In Manitoba they emerge mid to late May, or even early June.n southern Manitoba there is one critter that is particularly suited for a class room demonstration of survival at sub-zero temperatures. The larva of the Goldenrod Gall Fly (Eurosta solidaginis) is both common and easy to get.
There are two groups of flies that do have larval stages that live on or in human skin. One, the human bot fly (Dermatobia hominis, family Oestridae), has large, 1-2 cm (Â½-1 inch) long, larvae that live and feed in the skin. These flies are not found in North America, only in Central and South America.However, there are rare cases of rodent bots infesting humans in California.The other flies, with larvae that feed on humans, are screw worms and blowflies (family Calliphoridae). The larvae of these flies feed on dead or decaying tissue, and less commonly living tissue.owever, there are rare cases of rodent bots infesting humans in California.
