Lucky glimpse of a humming bird hawk-moth (11/10)


 

This morning we had a hummingbird hawk-moth visit our garden. It was hovering around the blue flowers of a hardy plumbago plant. I have seen them in previous years but never so late as this & they’re normally attracted to the flowers of either buddleia or red valerian. The flowers of the latter are virtually finished now & the hardy plumbago is one of the few plants still produclng reasonably nectar-rich flowers this late in the season.

Hummingbird hawkmoths chiefly inhabit the Mediterranean area but each spring a number of them migrate northwards to the UK. They normally arrive from early June onwards & some remain to breed. They lay their eggs on either bedstraws or wild madder but occasionally, have been known to lay them on red valerian, The cycle from egg to adult moth is around 8 weeks. In late summer the majority of the adults return to the Mediterranean but a few individuals attempt to overwinter here. The majority will not survive the cold but in recent years with climate change leading to milder winters an increasing number of these attractive moths are making it through to re-emerge in the spring. I hope our visitor will be one of them.
