Forest Bug

Pentatoma rufipes


At first glance, the Forest Bug appears similar to the other 'spiked' shield bug species; however, the shoulders are square-cut and rounded at the front, which makes it quickly identifiable. It is also found in different habitats to other shield bugs: the Forest Bug is mainly herbivorous, feeding on the sap of deciduous trees, particularly oaks growing along sheltered woodland edges or in clearings. This species overwinters as a nymph, the adults are present from July to November, and eggs are laid in August.

How to identify

One of a group of three brown shield bugs with shoulder 'spikes', the Forest Bug is best distinguished by its square-cut shoulder 'spikes' and black- and cream-chequered flanks.

How can people help

The Wildlife Trusts manage many woodland nature reserves for the benefit of all kinds of animals from minibeasts to mammals: a mix of coppicing, scrub-cutting, ride maintenance and non-intervention all help woodland wildlife to thrive. You can help too: volunteer for your local Wildlife Trust and you could be involved in everything from traditional forest crafts to surveying for insects.
