Notes on the Commoner Species 14 1 



The adults are not very delicate, females of A. 

 maculipennis having lived in the laboratory for as 

 long as 7 days on dried figs, with no water. One 

 punctipennis, cap- 

 tured and given 

 blood December 12, 

 lived nearly 7 days 

 without any other 

 food, even water. 



The eggs resist 

 drying fairly well. 

 Some ova of A. 

 crucians laid on the

 were then floated

 of April, the adults 

 issued the 13th.

 our characters by identifying collected live wigglers
