The stridulation of Atlanticus testaceus has been described in the literature (Cantrall, 1943, Davis, 1893, et al), so its general character is well known. Other apsects of the stridulation and associated behavior are not as well known. The pitch of the call is altered under cool conditions and becomes a short, sputtery creak rather than its usual zzzzp-zzzzp-zzzzp-zzzzp expressed again and again. It appears that more than one kind of call characterizes the species. There may possibly a distinct mating sound, for a mature female approaching a calling male may elicit a change in his even trill to a slower, interuppted clatter. There is sometimes an alarm call. Atlanticus males, when picked up or otherwise disturbed, sometimes emit a single loud zik, often in association with escape behavior.
