The phallic structures in Gryllotalpidae (Orthoptera: Gryllotalpoidea), and its generic implications.

The phylogeny of mole crickets (Orthoptera: Gryllotalpoidea: Gryllotalpidae).

The monophyly and phylogenetic relationships of the family Gryllotalpidae were researched. Twenty-six in-group taxa, representing all known genera of Gryllotalpidae were included in a cladistic analysis, based on 89, morphological characters (including genital characters of the males). The different analyses of the resulting data matrix supported the monophyly of Scapteriscinae and Gryllotalpin...

Wing dimorphism of European mole cricket Gryllotalpa gryllotalpa (L.) (Orthoptera: Gryllotalpidae) in the north-west of Iran

The seasonal study of wing dimorphism in the European mole cricket, Gryllotalpa gryllotalpa (Linnaeus, 1758) (Orthoptera: Gryllotalpidae), was carried out in northwest Iran. Based on present research, the long-winged (LW) morph appeared in early-mid spring when vegetation density is low and the crickets need to fly to search for food. Study of foretibiae showed that the dactyls are elongated an...
