temperature of 69.9° F. In periods of cooler weather the stage 
may be prolonged to 15 days. 
Pupartum. The puparium of wheelert, as in all ecalliphorid 
species, has most of the external characters of the mature larva. 
The pupation period covers 8 to 14 days at a mean air tempera- 
ture of 72.2° F., but may be prolonged to 49 days or perhaps 
longer, depending upon weather conditions. 
Adult. Both sexes of wheelert may be collected in careass- 
baited traps; as many as 3,072 were collected by this means in 
Arizona during the latter part of March, 1938 by C. C. Deonier 
(Deonier and Knipling, 1940), who found that captured gravid 
females deposited readily on lean meat. He also collected gravid 
females in nature upon a dog carcass. The specimens which I 
have collected were attracted to myiasis wounds, to carcasses, or 
upon foliage where the adults apparently sun themselves during 
the early morning hours.

Paralucilia fulvipes apparently does not occur in the North 
American fauna, but, since fulvipes and wheelert have been 
confused under one name for many years by all authors except 
Townsend, it has been necessary to obtain considerable informa-
