 STRIPED EAKFLY. 



((In'jisops vittalus \Vied(Mnann.) 



This is a eonnnon species in Louisiana, for- 

 which reason its life history may he properly 

 considered in this paper. Personally. I have 

 Mot worked out the life history of this particu- 

 lar species fully, so it seems best to <pK)te as fq^ahuivv^ hnuHaJ. 

 follows from Hart's paper "On the Kntimiolo^y I'l^^j^^-'^jl^^iil^^if^t^;; 

 of the Illinois Kiver and Adjacent Waters." pub- t^"''- Volume iv.>

 oratory of Xatui-al History, Pape 228: 



"The larvae were found in conneclion with other larvae in a weedy 

 and swampy brook. They were quite common, occurring in the mud 

 and the mats of dead stems, and rarely floating at the surface. The 

 first were seen March 28. but they continued to occur up to April 15, 

 increasing slightly in size. In the breeding cage they burrowed into 



the mud and vegetation. In the latter part 

 of May the water was allowed to dry up, 

 and on the 28th, all that remained was 

 poured oif. June 1 to 3, three pupae were 

 formed in the damp mass of dead vege- 

 table matter resting on the mud in the 

 cage. Two imagoes emerged .June 9, both 

 males, the third failing to transform. The 

 coiorafjon of the larva readily distin- 

 guishes it.
