WHITLINGHAM: September count and lots of Oak associates

11th September 2022

Highlight of the WeBS count was one Wigeon.

I spent a little while looking at an Oak, and found quite a few galls, leaf mines and caterpillars, most of which are pictured below. I also saw some Variegated Oak Aphids, including an alate (winged adult) which was a first for me, having only seen non-winged ones here previously.

Moth leaf mine - Tisheria ekebladella

Heliozella sericella mine and cut-out

Oak Marble Gall
Variegated Oak Aphid
Trioza remota galls
Stigmella sp. leaf mine
Oak Knopper gall
Artichoke Gall
Neurotus anthracinus gall
Smooth Spangle Gall

Buff-tip caterpillar
Caloptilia sp.

Coleophora 'flutipennella'

I also found a hawk moth caterpillar - Poplar Hawk or Eyed Hawk (it doesn't look quite typical for either unfortunately) being attacked by a wasp


WHITLINGHAM: August WeBS count, ivy insects and more...

 23rd August 2020

This months WeBS count was rather late in the month, and many of the swans and geese had moved on from the late July peak counts. The vegetation was quite high around the Little Broad, amking it tricky to see in from many angles, but whilst looking I noticed that a patch of Ivy had come into flower. There were no Ivy Bees yet, but lots of wasps, Hornets, hoverflies and greenbottles. I did pick out, a larger, darker wasp, and from the markings was able to confirm that it was a Median Wasp, which was nice.

In terms of wildfowl, there was nothing out of the ordinary. A Mallard had a young duckling, perhaps a third brood, and at least five of the Mute Swans were sporting the local colour rings. A selection of comparitive counts are below. The difference in Mute Swan numbers is probably due largely to the timing of the count - by September 2019 numbers had dropped to 20.

  • Mute Swan 17 (2019: 74)
  • Canada Goose 14 (2019: 4)
  • Mallard 76 (2019: 101)
  • Coot 12 (2019: 7)
  • Cormorant 28 (2019: 11)

A selection of other species of interest included Bronze Furrow-bee, a parasitised aphid on Alder, a leaf mine on Canadian Goldenrod caused by Nemorimyza posticata and a smut fungus on Water Stitchwort. The trip had a frustrating conclusion. Earlier in the month some people had come and stolen many of the railway sleepers that used to line the car park. This meant that in order to park you had to pay attention to the well-worn parking places and use some common sense. Unfortunately this proved beyond some people, who parked in a row that completely blocked in an existing row of cars, including mine. I therefore had to just wait by my car until someone came back and left, allowing me to get out. It didn't look much better along the lane either, with two cars parking between the 'no parking' bollards, and at least one other car on double-yellow lines a bit further down.






NORWICH: Mousehold solitary wasps

21st July 2016

As it was still hot after work on Thursday I headed up to Mousehold Heath to have a look for butterflies and anything else that might be of interest. Along one of the footpaths were a row of holes made by digger wasp spp. I watched them flying in and out, although they were tricky to observe, flying in close to their burrow and peering out before they emerged.




Before leaving I checked along one of the woodland edges where White Admirals have been reported before. I didn't see any, but did see a new hoverfly, Xylota sylvarum (although the angle makes it look a bit like X. xanthocnema here so I might get a second opinion). I also gathered a few leaf mines to try to key out.
