Gryllidea
crickets
Gryllidea is an infraorder within the suborder Ensifera comprising crickets and their relatives. The group contains two superfamilies—Grylloidea (true crickets, tree crickets, scaly crickets, and allies) and Gryllotalpoidea (mole crickets and ant crickets)—encompassing more than 6,000 described species globally. Members are characterized by acoustic communication through stridulation, with males producing species-specific songs to attract mates. The infraorder originated in the Triassic period approximately 250–200 million years ago and represents the third most diverse group within Orthoptera.

large squaregill mayflies
Neoephemeridae is a small family of mayflies in the suborder Furcatergalia, containing approximately 13-17 described species across four genera: Neoephemera (Nearctic), Ochernova (Central Asia), Leucorhoenanthus (West Palearctic), and Potamanthellus (East Palearctic and Oriental). Nymphs are characterized by distinctive fimbriate (fringed) dorsal-oriented gills on abdominal segments, giving rise to the common name "large squaregill mayflies." The family has a disjunct Holarctic-Oriental distribution with recent findings in southwestern and northwestern China linking previously isolated genera biogeographically.
