An empty cocoon

I must admit that, at first sight, this object, which was lying on a dirt path in a paddock in my local country park, had me completely baffled. I even poked it with the toe of my shoe, thinking it might be poo. But, once I looked closer, I could see the outline of wings and realised it was an empty cocoon. But of what?

Once I got home, I checked through the pupa images on Peter Eeles’s excellent UK Butterflies website but nothing seemed to fit. So, I posted photos of my find on Twitter and asked the man himself for help. Peter very quickly identified the cocoon as that of an Elephant hawk-moth (Deilephila elpenor), a beautiful creature that I’ve not yet seen (click on the moth’s name to see a picture on the UK Moths website). At least now I know they can be found nearby.

I don’t find pupae very often so I was very pleased to find these – all the black oblong shapes, not just the one outside the leaf – the pupae of the leaf-mining fly Cerodontha iridis. More about that creature in my blog post of 7 December.

It’s a Comma!

I’d seen the stunning Comma butterfly (Polygonia c-album) before, when I lived in Cheshire for 6 months, but this was my first in Wales and the first for 2016. And, surprisingly for a butterfly that can be quite skittish, it was very amenable to photography, fluttering off and coming back to a nearby leaf and changing its pose so I could get a variety of shots – a born model!

Named for the small white comma-shaped mark on the underside of its wings, the Comma is a resilient species. The main food plant for its caterpillars used to be the hops used in brewing beer so the butterfly’s numbers dwindled perilously when hop farming declined in the 1800s. For some reason, the Comma has changed its larval food plant to the Common nettle so, since the 1960s, both its numbers and the extent of its range have increased dramatically. It’s a born survivor!

You can just see the little white comma on the underwide of the wing in the photo above left. On the right is the pupa – a beautifully textured structure, with small silver highlights. And below is a rather battered-looking older specimen, seen when I lived in Cheshire.
