ACADIAN FLYCATCHEK. 



59 



8.15 per cent of the food, and are not taken as regularly as Hymen- 

 optera and in October are not eaten at all. They were noted in 39 

 stomachs and were the sole contents of 1. Most of them are of the 

 housefly family, but a few long-legged crane flies were found in 5 

 stomachs. Bugs are eaten still less than flies. They amount to 

 6.03 per cent, but are not taken very regularly and not at all in Octo- 

 ber. They were contained in 29 stomachs and consisted of such 

 fa mili es as the leaf hoppers, tree hoppers, stinkbugs, and assassin 

 bugs. 



Orthoptera were found in 1 stomach taken in Florida in April and 

 2 collected in Pennsylvania in September, but the percentage in each 

 of these 3 stomachs was so great that the amount for the whole season 

 is 6.38 per cent of the food, or more than the last item. The contents 

 of the Florida stomach could not be determined further than that 

 they were orthopterous, but the contents of the other 2 were identified 

 as (Ecanthus niveus, the snowy tree cricket, known in some places as 

 the August bird. As these creatures are rather nocturnal in their 

 habits and not much given to flying at any time, it is rather surprising 

 to find that a flycatcher had nearly filled its stomach with them. 



Moths, in both the adult and larval form (caterpillars), are second 

 in importance in the animal food. They are taken pretty regularly 

 in every month, but with some falling off in July. The amount for 

 the whole season is 18.87 per cent. They were found in 38 stomachs, 

 of which 31 contained caterpillars and 8 held moths; 3 contained no 

 other food. No special pest was observed among them. A few 

 miscellaneous insects, such as dragon flies, scorpion flies, and a few 

 insects not identified, amount to 0.99 per cent, and have no special 

 interest. Spiders and millepeds were eaten in moderate quantities 

 from April to August. They amount to 2.94 per cent and complete 

 the quota of animal food. As usual, many of them were the long- 

 legged harvestmen or daddy longlegs.
