Rose Midge

A tiny gall midge whose larvae develop inside rose buds, causing them to blacken and fail to open. Adults are delicate yellowish flies barely visible to the naked eye.

💡

Did You Know?

A single rose bud can contain dozens of tiny orange larvae that destroy the flower before it ever opens.

Shiny Lined Rove Beetle

A distinctively elongate rove beetle with a shiny black head and pronotum, and reddish-brown elytra. It hunts in narrow spaces and is commonly found in synanthropic habitats.

💡

Did You Know?

The disproportionately large mandibles of this beetle, relative to its narrow head, allow it to subdue prey in tight spaces where it has a significant advantage.
