UK Field Cricket Conservation: Rearing and Release

The field cricket is one of the UK's rarest insects, reduced to a single wild population with captive breeding and reintroduction now underway.

Key Facts

The field cricket was reduced to a single population at Funtington, West Sussex by the 1990s
A captive breeding programme at London Zoo has enabled reintroduction to multiple historical sites
Field crickets require warm, south-facing grassland with bare patches for burrow construction
Annual monitoring confirms establishment at several reintroduction sites in southern England

Welfare Considerations

Individual field cricket welfare in captive breeding settings requires appropriate temperature, humidity, and social conditions. Reintroduction welfare depends on suitable habitat being available and free from inappropriate pesticide use. This programme represents invertebrate conservation and welfare at its most intensive.

What You Can Do

Support wildlife conservation organisations running insect captive breeding programmes
Advocate for warm, south-facing grassland management in agri-environment schemes
