HOSTS 



At the present time we have definite evidence of larval A. 

 confusus from only a few species of insectivorous bats; Chaer'ephon 

 major and Taphozous perforatus haedinus (Equatoria records above); 

 questionably (host field determinations not checked by a specialist) 

 from Eptesicus pusillus and Fachyotus sp. (Equatoria records above); 

 and from Eptesicus capensis , Fachyotus sp. . Miniopterus natalensis 

 arenarius , Taphozous _£. perforatus , T. (L. ) nudiventris , Otonycteris 

 h. hemprlchi , Nycteris t. thebaica , "and Tadarida a. aegyptiaca 

 "(Hoogstraal 1955B). Nymphs and adults found in bat-infested caves 

 and biiildings probably feed on the same species of hosts as do 

 larvae. 



The record of A. confusus (= A. vespertilionis ) attacking pen- 

 guins in Queens town7 Cape Colony (Nuttall et al 1908) must be re- 

 garded as questionable (Hoogstraal 1955B). 



BIOLOGY 



Life Cycle 



A. confusus has been reared in our laboratory at temperatures 

 between SQOF. and 90°F. and at relative hximidities between U% and 

 5Q&. A single egg batch consists of from forty to seventy eggs 

 with fifty to sixty the most common quantity. Eggs hatch from 21 

 to 25 days after being laid. Larvae have commenced feeding five 

 to 26 days after hatching. The duration of larval feeding varies 

 from five to fifty days but most larvae drop from the host in two 

 or three weeks. Afterwards, larvae remain quiet for seven to 

 twelve days before the nymphal molt.
