This little parasite has been credited with puncturing the 
Hessian fiy eggs and laying its own therein to hatch later 
and consume the larva. This was considered a very improbable 
method of attack, as most true egg parasites complete their life 
cycle within the egg itself though the observations of Marchal 
on Trichasis have shown the probability of such a mode in 
this species. |

Riley who received parasitized pupae from Fred Enoch of 
England. These were distributed to Prof. Forbes of Illinois,

in Illinois, but whether it will continue to hold its own and prove 
an efficient aid in the control of this serious pest remains to be 
seen. 
Two other primary parasites of the Hessian fly are known in 
America. They are Pteromalus pallipes Forbes and 
Eupelmus allynii French.
