Preliminary investigation of the drumming signals of Taeniopteryx nebulosa ssp britannica Hynes, 1957 (Plecoptera: Taeniopterygidae)

The male drumming signal of the stonefly Taeniopteryx nebulosa from Great Britain is described for the first time. It differs significantly from calls of European males in terms of number of beats and total call duration. As such, it justifies continued consideration of British specimens as a subspecies. Despite there being only one specimen examined we thought it was important to note the differences observed and to consider the significance for the status of the British subspecies.
