pine tree cricket
Oecanthus pini

Male on tamarack, Silver Lake Bog, Kenosha County, Wisconsin.
This locality is outside the range of O. laricis, which is known only from specimens associated with tamarack in Michigan and hemlock in Ohio.
This specimen was identified as O. pini rather than O. laricis because its caudal femur is green rather than brown
and because it readily mated with a female of pini (see next image).
