The dock bug belongs to a group of insects known as squashbugs, which are related to shieldbugs. It is one of the most commonly encountered squashbugs, often found sitting out in the open on the leaves of docks, nettles, brambles and other low vegetation. If you spot one dock bug, search around and there are likely to be many more in the area. Adults become active in spring, with nymphs developing into new adults in late summer.
How to identify
A large, brown bug with prominent 'shoulders' and a broad, rounded body. The long antennae end in darker tips. There are two small horns on the head, between the antennae, which are not present in any similar species.
Distribution
Found widely across Wales and England north to Yorkshire, with scattered records from further north.
Did you know?
Dock bugs can sometimes be seen feeding on blackberries. They use their long, piercing mouthparts (called a rostrum) as a straw to suck up the juice.
