of depositing as many as or more repagula than eggs at any given 
time, since each modified ovariole can store many more “mature” 
repagula than a normal ovariole can eggs. Stored repagula show 
no trace of the reddish color characteristic of oviposited repagula, 
suggesting that the red fluid is secreted by some accessory gland at 
the time of deposition. 
B. Ascaloptynx furciger (McLachlan) 
Adults of Ascaloptynx furciger are active earlier in the summer 
than U. mexicana , seemingly being most abundant in southeastern 
Arizona during the rainy season, from early June to early September. 
As in Ululodes , males become less common in the latter half of this 
time period. Eggs are in greatest evidence during August, with 
chalcidoid parasitism destroying 95 percent of the egg-masses de- 
posited after September 1. Again like Ululodes , ovipositing 
Ascaloptynx females are extraordinarily habitat specific, yet display 
little preference for particular plant species: eggs are laid on the 
thin terminal dead twigs of any one to two foot perennial or grass 
clump growing in protected semi-shaded locales in the foothills of 
the mountains, where rainfall is relatively great and scrub oak 
( Quercus emoryi and 0 . arizonicus) and juniper ( Juniperus dep- 
peana ) abound. In contrast to Ululodes J vertically oriented twigs
