Mating behavior of the long-legged cricket Eidmanacris meridionalis Desutter-Grandcolas, 1995 (Orthoptera: Phalangopsidae)

Pair-formation, courtship, copulatory, and post-copulatory behaviors of Eidmanacris meridionalis Desutter-Grandcolas, 1995, were described under laboratory conditions compared with congeneric species other Phalangopsidae crickets whose mating behavior has been previously studied. Field observations for the are also reported. Mating observed in E. couples: they first remained motionless, then began walking through arena screening substrate. started antennal contact, followed by males positioning themselves front females, that, when receptive, mounted on back feeding metanotum secretions males. Copulation (female-above-male position) engaging copulatory structures stopped couple detachment. The end-to-end position was once, right after Males always spermatophore, which eaten removal or, alternatively, left main differences regard duration reproductive stages, suggesting that repertoires can be genus since 27 have not yet studied regards their behavior. We assume morphological, genetic, chemical diversity found among reflects pair-formation, copulation, post-copulation, leading to a copulation positions, methods attracting partners parental investment. description patterns provide important information future evolutionary phylogenetic studies, apart from useful distinguishing cryptic species.
