Acroneuria abnormis
(Newman, 1838)
Common Stone
Acroneuria abnormis, commonly known as the common stone, is a of in the Perlidae. It is widely distributed across North America. The species is notable for its drumming during mating, which produces species-specific vibrational signals used for identification and mate recognition.

Identification
Can be distinguished from similar by species-specific drumming signals produced during mating . As a member of the Perlidae , it possesses the characteristic robust body and wing venation typical of common stoneflies, though specific diagnostic morphological features for this species require examination.

Distribution
North America, with records from Alberta, Alabama, Connecticut, Colorado, and Delaware.
Behavior
During mating, pairs engage in drumming — produced by tapping the substrate—that produces -specific signals. This drumming can be used to identify the species.

Mating Communication
The drumming of A. abnormis represents a well-documented case of substrate-borne in stoneflies, with signal patterns serving as pre-mating isolation mechanisms.
