The following observations upon the mating habits are given: 
May 14, 1912. At Renwick, Ithaca, N. Y., this species was swarm- 
ing about 4:30 P. M.; many were "in cop" on the leaves of skunk- 
cabbage, Symplocarpiis fatidus. There were about 15 or 20 
individuals in a swarm, which takes place about a foot above the 
skunk-cabbage leaves. Copulation is rather firm and they fly for 
short distances still united. In copulation they usually rest on the 
upper surface of the leaves with all the legs on the support. 
Swarms were noted consisting of from 1 to 20 individuals, and 
usually from 6 to 12 inches above the leaves. At this time the only 
adult crane-fly found with Ula was Limnophila ultima Osten Sacken, 
which occurred in small numbers.
