December Moth larvae hatch

These eggs were laid by a female December Moth back on 16 Nov 2004 and have just hatched. The larvae are 4mm long and this is currently the scene in their pot.

Andrena cineraria

This is a great-looking black and white bee. Many thanks to Stuart Roberts confirming the identification. It was in Stonepit Quarry at Old Sulehay, Northants.

Garden Tick

358th species recorded in the garden so far. An attractive geometrid, whose larvae feed on Spindle (Euonymus europaeus) and have two broods a year with adults flying in May/June and again in August.

Of Cuckoo Bumblebees and other things

A rare outing to the Brecks of Norfolk to see the late neolithic flint mines of Grimes Graves and some old woodland haunts. We also dropped into Weeting Castle, which, while not much of a castle, was home to several interesting insects.

Having newly acquired an excellent Bumblebee ID guide I was keen to try it out and soon came across this, my first Cuckoo Bumblebee. It is a cuckoo (or "obligate social inquiline" as one paper put it!) in the nests of Bombus pratorum.

Bombus sylvestris



Alex was doing a good job of finding things. This caterpillar was hidden under a small piece of stone. It feeds on lichen, which was plentiful on the ruins.

Marbled Beauty (Cryphia domestica)



This larva proved tricky to pin down, but thanks to Nick Greatorex-Davies and Colin Welch we have narrowed it down to a Soldier beetle (Cantharidae), probably in the genus Cantharis.

Another of Alex's finds was this small shieldbug, which is apparently quite hard to locate.

Pied Shieldbug (Sehirus bicolor)


Finally here is a rather poor shot of a Fox Moth larva. These are easy to find at this time of year as the fully fed caterpillars, that have hibernated through the winter emerge and set off to find somewhere to pupate.

Common Tern

Dropping in on Ferry Meadows on the way home from work is becoming a habit. An Arctic Tern seen earier in the day was nowhere to be seen but this Common Tern was among many there.

Little Gulls

On impulse I dropped in to quickly scan Gunwade Lake at Ferry Meadows on the way home from work this evening. This has sometimes proved worthwhile (e.g. Brent Goose and Otter) and this time it was the delightful sight of eight Little Gulls dancing over the water. All but one (a third year) were in their second calendar year.

They were on the go all the time so photography wasn't really an option but I tried a few digiscoped flight shots anyway.

Common Seal

I always take a look for the long-staying Seal at the Dog in a Doublet when I pass but haven't seen it for quite a while. Perhaps that is because it has been for a trip up the Nene. This morning it was hauled out on the banks of the non-tidal section of the river about halfway along the north bank road opposite Holly Tree. I once saw a Common Seal right up at Orton Lock so this one could turn up anywhere along the river.

Bee-fly

Coming back from a weekend in Suffolk it was nice to spend a couple of hours in the garden in the warm sunshine. A House Martin zipped overhead at one point and there were plenty of bees at large. The west wall of the house was particularly warm and several insects used it to bask including this handsome Bee-fly.

Square-spotted Clay

I've only just started making a concerted effort to locate the breeding signs and non-adult stages of lepidoptera in my garden, so it is encouraging to come across a significant find like this so soon.

This is a very locally distributed species with a stronghold in parts of East Anglia and is designated "Notable B". A recent study has found it in suitable habitat in several parts of East Anglia including the Peterborough area.

These two were feeding on Primula, although it has been recorded feeding on other low plants as well as this. The next challenge is to record the adult. They are scarce at light and come more readily to sugar or flowers.

Make like a stick

This is a common moth in the garden as an adult but its nice to confirm it breeding. It feeds on Ivy (Hedera).

This camouflaged defensive pose is typical of many of the geometers or measuring worms (Geometridae).

Wood Anemones

Old Sulehay is worth a visit at any time of the year but the activity now is great. Three species of woodpecker and Nuthatch all very vocal and the display of Wood Anemones is spectacular.

Wood Anemone (Anemone nemorosa)


This is formed by a small gall wasp on the broken stems of bramble. Each galls contains many larvae. They were abundant in just one patch of the wood.

Spring signs

The Sallow blossom was smelling strongly and carpets of Violets brightened up Stonepit Quarry at Old Sulehay.

Robin failure

The Robins that nested so quickly in the new PBC nestbox in our garden proved to be rather unsuccessful on this attempt. The adults were noticed spending long periods off the nest and sure enough it was abandoned a couple of days ago. The clutch of eggs were cold. They will no doubt make another attempt.

Grey Wagtails, Maxey Cut

Maxey GP was back on the radar today following a Rock Pipit there in the morning. No sign of that at lunchtime but a singing Chiffchaff, 5 Green Sandpipers, 1 Dunlin, 1 Redshank, 3 Shelduck among others and this pair of Grey Wagtails feeding photogenically on the Maxey Cut
