Description

Wing span: 64 - 76mm; Body length: 42 - 45mm

Teneral male Scarce Chasers are a vivid orange colour, which turn into black and grey-blue adults. Females are brown. Both sexes may have dark wing tips.

It is found quite widely in central and SE Europe, but is scarce in the British Isles.

The Scarce Chaser appears to require a specific combination of water quality and habitat structure. Reedy borders are favoured. Slow-flowing rivers and streams, abandoned canals, ox-bow lakes, etc, are typical habitats.

Nymphs take two years to mature. Adults are on the wing from the end of May to early August.

Males frequently perch on waterside plants, making darting flights between perches.

The Scarce Chaser is a Red data list species in the UK.
