Abstract

The drumming of Acroneuria evoluta and Doroneuria baumanni is described for the first time, and additional signals of A. lycorias and Phasganophora capitata are reported. The three-way signals of A. evoluta are the most complex yet reported in Plecoptera; males call with diphasic signals produced by combinations of abdominal tapping and rubbing, females answer with 4.8 ± 1.5 beats spaced at 48.0 ± 4.2 ms intervals and males reply with tapping signals of 5.9 ± 0.8 beats. Male D. baumanni call with two prolonged rubs of the hammer on the substratum, and females answer with 9.1 ± 0.7 beats spaced at 129.6 ± 5.0 ms. Females also occasionally drum without a male call stimulus. P. capitata males call with tapping signals of 14.0 ± 5.5 beats spaced at 411.9 ± 19.9 ms, and females answer with an unusually long sequence of 145.1 ± 54.5 beats having 418.1 ± 33.5 ms intervals. Female A. lycorias answer taped male signals with 5.8 ± 1.3 beats having 50.9 ± 7.6 ms intervals. Out-group comparisons utilizing drumming data from 50 North American species in eight families indicate that drumming signal production by rubbing in some Perlidae is a derived character. Ancestral and derived expressions of almost all the basic character states known for drumming in Plecoptera are exhibited in the 16 Nearctic Perlidae species whose signals have been described.
