Species text

The species has a patchy and scattered distribution in Britain, but is absent from large areas. It has been recorded from most of the countries in north-western and central Europe.

Habitat and ecology
In southern England J. falconeri is found in open, stony areas on heathland and in the top layers of soil. It has also been found on calcareous grassland, in pine needles and under stones. Adults occur in spring and autumn.

The species appears to be uncommon and to have shown a steep decline in the past 20 years. However it is so small that it is unlikely to be caught except in pitfall traps, and even then it is hard to spot.

Loss of heathland and calacreous grassland to agricultural and urban development. Scrubbing over of heathland and calcareous grassland.

Management and conservation
Prevent loss of heathland and calcareous grassland. Ensure that scrub invasion in these habitats is controlled.
