Brown-tail

Thinly scattered across the
county but more common coastally.&nbsp;
Appears to have colonised the county relatively recently, with very few
records before the mid-1980s and being almost annual since, increasing in
frequency in recent years.&nbsp; The hairs on
the larvae can sometimes cause severe allergic reactions.

Black Arches

Widespread and fairly common across the county, gaps in its distribution coinciding with under-recorded areas.&nbsp; A visitor to gardens in small numbers, but far more common in woodland.

Gypsy Moth

A former resident in East Anglian fens, this species became extinct before 1900 but has since become re-established as a resident, immigrant and adventive.&nbsp; On mainland Europe, where it is often a pest, it is found in a variety of habitats, where the larvae feed on broadleaved trees and bushes. There have been five records in the county, in 1992, 2023 and 2025 (3).
