Aphaenogaster carolinensis
Carolina Collared Ant
Aphaenogaster carolinensis is a medium-sized ant species in the family Formicidae, first described by Wheeler in 1915. The species is notable for its documented substrate vibration generating behavior, in which workers strike and drag their mandibles against surfaces to produce vibrations. This behavior occurs most frequently during confrontations with non-nestmate conspecifics and does not require the presence of food or territory to be initiated.
Trigonidiidae
Sword-tailed Crickets, Ground Crickets, Wood Crickets, Trigs
Trigonidiidae is a family of small crickets within the superfamily Grylloidea, comprising two subfamilies: Nemobiinae (wood/ground crickets) and Trigonidiinae (sword-tail crickets). Members are typically small-bodied with diverse habitat associations ranging from woodland leaf-litter to sandy beaches and urban parks. The family exhibits complex acoustic communication, including calling songs, courtship songs, and substrate-borne vibrational signals in some species. Several genera, including Anaxipha and Cranistus, have been documented using drumming behavior during courtship. Many species remain poorly known, with ongoing taxonomic work describing new species primarily from China and other regions.
