Grylloidea is a large superfamily of orthopteran insects, comprising over 4,000 species in four extant families (Gryllidae, Mogoplistidae, Gryllotalpidae and Myrmecophilidae) and two extinct families (Baissogryllidae and Protogryllidae) to date (Resh & Cardé, 2009; Cigliano et al., 2018; Wang et al., 2019). Grylloids, commonly known as true crickets, are a group of adaptable insects occurring in all the temperate parts of the world except the highest mountain peaks. And interestingly, there are several apterous grylloid genera (e.g., Caconemobius) living in mangrove swamps, where they use the stems to submerge themselves in saltwater and are able to “skate” on water surfaces (Resh & Cardé, 2009; Kim & Kim, 2010).
