Amorpha Borer

Many thanks to Andy Reago & Chrissy McClarren who made the really nice find of these two amazing long-horned beetles, the amorpha borer, Megacyllene decora. While hunting rare birds at Columbia Bottom, C.A., we luckily ran into these guys and were able to take advantage by getting some photos. This was the first time I have seen this species in person.

2024 Caterpillar Season – Mottled Prominent

The mottled prominent (Macrurocampa marthesia) is found in the Notodontidae family and is a relatively common caterpillar found on oaks and other members of the Fagaceae. The long tail-like appendages are the anal prolegs and are quite long in early instars, becoming progressively shorter with each molt. Each of these animals were found in mid-late August at the Schoolcraft Prairie property in Washington County, Missouri.
