Phylogeny of the Ensifera (Orthoptera): A Hypothesis Supporting Multiple Origins of Acoustical Signalling, Complex Spermatophores and Maternal Care in Crickets, Katydids, and Weta
The orthopteran suborder Ensifera is a group of interest to many biologists because members of several families within this group communicate by sounds. The evolutionary history of singing and otherExpand

Sex-biased predation and the risky mate-locating behaviour of male tick-tock cicadas (Homoptera: Cicadidae)
In this study, web-building spiders captured more male than female tick-tock cicadas, Cicadetta quadricincta. The preponderance of males in webs was not due to a male-biased adult sex ratio butExpand

Condition Dependence of Male Life Span and Calling Effort in a Field Cricket
Abstract Sexually selected traits are thought to impose survival costs on showy males. Recent empirical work found a negative relationship between male display and survival in a field cricket speciesExpand

  • The American Naturalist
  • 1 September 1986
Studies indicate that courtship feeding in insects represents mating effort that evolved to ensure successful insemination. I tested this hypothesis with katydids (Requena verticalis), in which malesExpand

Sexual Selection for Male Mobility in a Giant Insect with Female‐Biased Size Dimorphism
Female‐biased size dimorphism, in which females are larger than males, is prevalent in many animals. Several hypotheses have been developed to explain this pattern of dimorphism. One of theseExpand
