Over the summer months I discovered how productive the solid fencing around this building site alongside the River Taff was for insect finds. A section of the fence along the access track to the site was where I saw my first Large white butterfly pupae and, subsequently, the parasitic wasps that preyed on them and were, in turn, the victims of other parasitic wasps (see Large whites and parasitism, part 1, 23 June and Large whites and parasitism, part 2, 24 June).

The interesting finds have continued with the changing seasons. Yesterday, when I walked slowly past, though there were several different creatures (including at least one Noble false widow spider), the highlights were moths, drawn to the wall, no doubt, by the lights that illuminate the wall at night. Yesterday’s finds were four Winter moths (Operophtera brumata) and a Mottled umber (Erannis defoliaria).

Caterpillar in a tent

While wandering through my favourite woodland earlier this week, I noticed small areas of damage on some Hazel leaves. It looked like a little critter had been munching on them and, checking further, I soon discovered a lot of leaves had suffered similar damage.

Closer inspection of one particular leaf soon revealed the culprit, a caterpillar, tucked away in a snug little tent it had created by binding two leaves together with silken thread. From there it could easily venture out to eat, yet retreat when threatened by predators or bad weather. Smart thinking!

I think the caterpillar may be the larva of a Winter moth (Operophtera brumata) but I haven’t yet been able to confirm my identification (Update 16/5: ID now confirmed as Winter moth). Once I was alert to their presence, I noticed more leaf damage and several more ‘tents’, as well as a smaller caterpillar feeding out in the open.
