Family Description

The most spectacular damselflies in Canada: large with metallic-coloured bodies and broad, densely veined wings, often coloured. Larvae develop in streams, clinging to plant stems and roots; they can be distinguished by their long antennae - the first segment is longer than all the others combined. Only one jewelwing lives in British Columbia.
Field Notes

Lives along small warm rivers and slow streams where the adults fly with a dancing, butterfly-like motion and perform striking courtship displays.


Transition. In B.C., found only along Christina Creek at Christina Lake in the southern interior.
