INSECTS 



The duration of life of the ichneumon fly depends on the species ; those which emerge in the 

 autumn may live through the winter. A great number that confine their attacks to one species 

 do not leave their habitation until the caterpillar is ready to receive the egg of the parasite, 

 passing at least ten months in the larva stage ; others pass through two or three cycles of existence 

 during the year, and do not confine their attacks to one or two species. 



There formerly existed, and perhaps still exists, among entomologists an idea that each species 

 of parasite had its own particular host, each to each, and no more. This, however, is fallacious ; 

 in breeding a great number it has been proved that they infest different species of Lepidoptera. 

 Thirteen parasites and hypeiparasites the writer has obtained from Abraxas grossuiartata, Linn. 



When an Ichneumon is said to be bred from a butterfly or moth, it is from the larva or pupa, 

 that should have produced the perfect insect ; a few beetles, (Coleoptera), and other orders are how- 

 ever attacked by parasitic flies when in the adult stage.
