Abstract

Phyllopalpus pulchellus Uhler (Trigonidiinae) is a small, diurnally-active cricket common throughout much of the eastern United States. Mating interactions in this species are here described based on observations of 14 mating pairs. Males produce two very different types of spermatophores: small, spermless microspermatophores which are removed and consumed by females shortly after transfer, and larger, sperm-containing macrospermatophores that are only produced following the successful transfer of a microspermatophore. A bell-shaped structure surrounding the sperm tube of macrospermatophores makes them more difficult for females to remove prematurely. Males’ production and transfer of spermless microspermatophores likely serve as a test of female receptivity prior to investing in a relatively expensive macrospermatophore that must be used within a short period.
