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, Symplocarptis fa^tidus. 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.
