  Black-spotted Chestnut Conistra rubiginosa  
         
 

B&F: 2259a

ABH: 73.196

Status: Resident

Distribution and Abundance: Rare - recent colonist

Primary Habitat: General distribution

Flight Period: Single brooded from October to March

Observations: First recorded in the UK in 2011, this species has gradually expanded its range to occupy several neighbouring vice-counties (e.g.: Bucks, Beds, Cambs, Hunts). The first VC32 record was of a single moth taken in one of the two Pitsford Reservoir light traps on 23rd December 2025. The moth seems to have quite a generalist distribution, being equally likely to turn up in gardens as woodlands, etc. Larval foodplants appear to include a wide variety of plants, trees and shrubs. Adults are active on milder winter nights and readily attend light traps, but, as with its congeners, can also be found on sugar and sap runs. That the first record came from a relatievly central area within VC32 suggests that it might be found elsewhere in the county - an excuse if ever there was to keep light traps running through the winter months.

Confusion Species: Red-headed Chestnut

L.O.N.: N/A

First Record: 2025, Pitsford Reservoir Traps (Gill, B).
