SOME OBSERVATIONS ON METRIOPTERA ROESELII (GRYLLOPTERA: TETTIGONIIDAE) IN MAINE, NEW HAMPSHIRE, AND MASSACHUSETTS

The Canadian Entomologist, 1974
AbstractMetrioptera (Roeseliana) roeselii (Hgb.) was first introduced into the Montreal, Que., area before 1952. By 1965 it had been collected in western and southern New York State. This paper records it from Maine, Massachusetts, and New Hampshire for the first time, and discusses the populations. Eventual establishment of M. roeselii over all of New

Demonstrating sexual selection by cryptic female choice on male genitalia: What is enough?

Evolution; international journal of organic evolution, 2019
Rapid divergence in external genital structures occurs in nearly all animal groups that practice internal insemination; explaining this pattern is a major challenge in evolutionary biology.

Changes in Dispersal during Species’ Range Expansions

American Naturalist, 2004
Explanations for rapid species’ range expansions have typically been purely ecological, with little attention given to evolutionary processes. We tested predictions for the evolution of dispersal during range expansion using four species of wing ...

[Electron microscope study of haemolymph cells of Metrioptera roeselii (Orthoptera, Tettigoniidae)].

Tsitologiia, 2002
On the basis of patterns of haemocyte ultrastructure and functions at preimago and imago stages of Metrioptera roeselii, secretory cells of granulocyte type were recognized in the haemolymph. The development of granulocytes was traced starting from their formation up to cell death and destruction.
