Birch Shieldbug

I have always liked shieldbugs. We don’t see them that often despite their colourful appearance, because they are also good at hiding. I am using my camera phone as my own camera is out of action, so not the best image!

They belong to the order Hemiptera, which is the same order as aphids, pond skaters and frog hoppers. They have a sucking mouthpath which they use to extract fluids from plants.

Hawthorn Shield Bug

I spotted two of these shield bugs while out for a walk along a track, we call the bog road, close to our house. It is a Hawthorn shield bug.

Hawthorn Shield Bug – final instar nymph

This is not it’s final adult stage. The female lays eggs that hatch into nymphs. These are wingless and crawl among plants and feed. They go through a number of instars. It takes about six weeks to reach an adult. They will hibernate during the winter months as adults. They feed mainly on hawthorn berries (hence their name), though this one was feeding on rowan berries.
