Insects of this order were found in the stomachs of seventy- 
three frogs, consisting of one imago, one chrysalis, and one 
hundred and twenty-one caterpillars. These larvae were 
eaten indiscriminately and constitute one of the most import¬ 
ant foods. Such hairy caterpillars as the larvae of the Tiger- 
moths and Fall Web-worms were present in several stomachs. 
Frogs taken at night or in the morning contained such noc¬ 
turnal larvae as cutworms (Agrotinae). 
Lepidopterous larvae are so easily digested that in many 
stomachs they were ground up beyond specific recognition 
and could not be identified beyond the family.
