Clifden Nonpareil (Blue Underwing) Catocala fraxini 15 Eggs

Clifden Nonpareil (Blue Underwing) Catocala fraxini

The largest underwing, spectacular blue. Store eggs refrigerated until May.

This species is now almost extinct in Britain. We are offering European stock of this fine moth, the largest of all Underwings and remarkable for its BLUE hindwings. The young larvae are immensely active and care must be taken when transferring them to fooplant on hatching, because they can tangle themselves up if you try to move more than one at a time! Feed on Aspen and other Poplars. The larvae are the largest of this genus and very satisfying to rear. Moths emerge in late summer, laying eggs that overwinter.
