BIOLOGr 



Aside from the fact that larvaa, nyn^ihs, and females are taken 

 on bats, nothing is known concerning the biology of I. simplex . 

 Males either do not take blood or feed very rapidly and quickly 

 secrete themselves thereafter; they sho\ild be searched for in re- 

 treats frequented by bats. Ixodes simplex is widely spread through 

 the tropics and temperate climates of the world and must be an uru 

 comnonly adaptable tick. Its hosts' ability to fly undoubtedly 

 accounts in part for the great range of this species.

RIMARKS 



The haller*s organ of both subspecies of I. simplex is like 

 that of I. vespertilionis (Arthur 1956b).
