Because of rather Siig are rearing methods an accurate 
check on the amount of food consumed during larval life has 
seldom been attempted. Quayle (12:511) kept sine of the 
amount of food consumed by the larvae of Oligota oviformis 
Casey. Over periods of twelve or fifteen days the ee vae would 
consume on an average of twenty spiders (small red spiders) 
per day. He did not succeed in obtaining pupae but felt that 
he had reared larvae thru most of their normal larval period. 
During the period he was able to keep larvae alive each would 
eat from two to three hundred red spiders. Most of the spiders 
were mature individuals as “they were transferred daily and 
consequently the eggs and small spiders would be left”. Adults 
ate about ten spiders per day. The maximum life recorded by 
Quayle was thirty-two days or a total of over three hundred 
for the period of observation. Adding larval and adult records, 
a single beetle during its life will consume upwards to six 
hundred red spiders. This does not give us an accurate quantity 
of food consumed but it does give us an idea of the amount 
of food these beetles will consume. Concerning the actual feed- 
ing of the larvae he says, 
“With its sharp pointed nage a8 the larva punctures the spider 
usually about the center of t body, a nd by a pump-like a action the 
resumed its nor col ity. Tis

I have observed larvae in sixty-nine of my cultures feed on 
the living food which I placed in the culture box, and many 
braceuelee Prdonthat proteins, Paederus littorarius and 
Gastrolobium bicolor. Further I have observed either in the 
laboratory or in the field the feeding behaviors of the adults of 
Staphylinus maculosus, Staphylinus violaceus, Staphylinus 
cinnamopterus, Creophulus villosus, Philonthus TRONS 
Olophrum obtectum and Stenus sp.
