Field Cricket

Males produce their characteristic chirping song by rubbing their wings together (stridulation). The rate of chirping is temperature-dependent, following Dolbears law.

💡

Did You Know?

You can estimate the temperature in Fahrenheit by counting cricket chirps in 14 seconds and adding 40 — this relationship is known as Dolbears Law.

Western Boxelder Bug

A red and black bug very similar to the eastern boxelder bug but found in western North America. It forms large overwintering aggregations on buildings and fences near boxelder trees. It is a nuisance pest but causes no structural damage.
