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.

Oleander Aphid

A bright yellow aphid with black cornicles and legs that feeds on oleander, milkweed, and other plants containing toxic cardiac glycosides. It sequesters these toxins for its own defense.

💡

Did You Know?

Its bright yellow color serves as aposematic warning coloration because it sequesters cardiac glycosides from its host plants, making it toxic to most predators.
