The Effect Of Male And Female Body Size On Mating Behavior Of Male Fairy Shrimp, Eubranchipus Neglectus, Craig Feigenbaum, Paul V. Switzer Jan 2007

The Effect Of Male And Female Body Size On Mating Behavior Of Male Fairy Shrimp, Eubranchipus Neglectus, Craig Feigenbaum, Paul V. Switzer

Paul V. Switzer

We studied size-related mating patterns in the freshwater fairy shrimp Eubranchipus neglectus in the laboratory. Males were provided with relatively small or large females that they could only sense by vision. We recorded the number of times a male pursued the female (“follows”), the duration of these follows, and the number of times a male attempted to grasp the female. Relatively large males performed more mating behavior than relatively small males. Furthermore, males (regardless of their own size) exhibited more mating behavior towards large than small females. They followed large females more frequently, attempted to grasp large females more often, …

The Cynipoid Genus Paramblynotus: Revision, Phylogeny, And Historical Biogeography (Hymenoptera, Liopteridae), Zhiwei Liu, Fredrik Ronquist, Goeran Nordlander

Zhiwei Liu

The genus Paramblynotus is the most species-rich genus of the so-called macrocynipoids, the large cynipoid parasitoids of wood-boring and cone-boring insect larvae. The species range in size from some of the largest to the smallest macrocynipoids, comparable in size to microcynipoids. Paramblynotus members occur on all continents except Europe and Australia, with most species being tropical or subtropical. The biology is poorly known but a few observations indicate that the species are parasitoids of beetle larvae. In this monographic revision of the genus, we present a species-level cladistic analysis based on qualitative and quantitative features of the external morphology. For …
