Last survivors


Despite the fact that we've had several frosts, there are still some wasps around, congregating on the flowers of ivy that provide a last chance for them to find nectar.

I found this wasp, which I think is a tree wasp Vespula sylvestris, crawling over the ivy flowers just as the rising sun melted the frost on the grass.

The dense covering of hairs on the wasp's body must provide some insulation against low temperatures, and it probably spent the night under the glossy, waterproof leaves of the ivy plant, which provides an overwintering site for all manner of invertebrates.

For more on the curious back-to-front life cycle of ivy, flowering in autumn and producing fruits in spring, click here.

  11. Hi Blackbird, I think the condensed moisture on the hairs has emphasised their presence
