Collins N, van den Berghe E, Carson L (2014) Two new species of Neoxabea, three new species of Oecanthus, and documentation of two other species in Nicaragua (Orthoptera: Gryllidae: Oecanthinae
Author's note: A bit of internet research helped us identify our perpetrator as a male tree cricket, a hard-to-see, but vociferous member of the family Gryllidae (true crickets), subfamily Oecanthinae
(tree crickets), and genus Oecanthus (common tree crickets).
The vast majority of prey were adult tree crickets (Gryllidae: Oecanthinae
; Oecanthus), although nymphal tree crickets and katydids (Tettigoniidae: Conocephalinae) also occurred among provisions.
In comparison to field crickets (Orthoptera: Gryllidae: Gryllinae), ground crickets (Orthoptera: Gryllidae: Nemobiinae), and tree crickets (Orthoptera: Gryllidae: Oecanthinae
), the acoustics and behavior of scaly crickets have received little attention.
Specificity in the response of the female tree crickets (Orthoptera, Gryllidae, Oecanthinae
) to calling songs of the males.
Diagnosis.--According to the current listing on The Orthoptera Species File (OSF), there are nine genera of Oecanthinae
worldwide, but only two occur in the U.S.

In May of 2009, one of us (NC) organized a field trip to find two species of Oecanthinae
known in the United States only from the lower Rio Grande valley and not collected there in more than 50 y.
Among the three distinct radiations of Hawaiian crickets (in the subfamilies Trigonidiinae, Oecanthinae
, and Nemobiinae) the swordtail crickets (Trigonidiinae) represent the largest, with more than 150 species currently hypothesized (Otte 1994).
