Seen in Area 5 of the Emm Brook by Kingfisher Bridge was the Hoverfly Leucozona lucorum . .This is a striking hoverfly with a white band across the upper abdomen and black wing patches that align with the black abdominal band .
Also seen on the Oak by the bridge were Knopper Galls Andricus quercuscalicis . These are formed by a tiny gall wasp, Andricus quercuscalicis, who lay eggs into embryonic acorn buds. The oak responds in an entirely specific way to this wasp by producing growths known as knopper galls, from a German name for a type of helmet.
They weren’t seen in Britain until the 1960s.
The Galls eventually fall to the ground and the wasp larvae wriggle out of vents in the galls next spring. The emerging wasps are exclusively female.

At this time of the year all along the Emm Brook the Common Red Soldier Beetle Rhagonycha fulva can be seen usually on Umbellifers .When I was a boy this beetle was known as "the bloodsucker". Who knows why, it was a long time ago.

A visit today to Area 8(Old Forest Road Meadows) in the blistering lunch time heat. The Sweep Net was deployed and found in the grass were Meadow Grasshopper Chorthippus parallelus and Hairy Shieldbug/Sloe Bug Dolycoris baccarum.
Cinnabar Moth Tyria jacobaeae caterpillars were feeding on the Ragwort. In a slightly bizarre moment a Lesser Diving Beetle Acilius sulcatus was found on the windscreen of my car.These are able to fly and can move between bodies of water.It was taken back to work ,placed in water, photographed and later returned and released.

During the walk up the river today pulling Balsam in Area 5 , Beautiful Demoiselle Calopteryx virgo damselfly were seen and Comma Polygonia c-album and Green veined White Pieris napi Butterflies.
03/07/18
In the carpark field in Area 10 at lunchtime, seen was a male Red-tailed Bumblebee
Bombus lapidarius .
Bombus lapidarius is probably the most easily recognised bumblebee species, with its black body and bright red/orange tail. The workers have the same colouring as the queen but are much smaller. The males also have similar colouring but with more yellow hair.

I was again in Area 10 carpark field at lunchtime, and seen was what I believe to be the larvae of the 14 Spot ladybird Propylea quattuordecimpunctata .
Also seen was the day flying Cinnabar Moth Tyria jacobaeae on Ragwort.

In Area 10 on a Dog Rose by the bridge over the Emm was a Smooth Pea Gall Wasp Diplolepis eglanteriae/nervosa. The gall is caused either by cynipid wasp Diplolepis nervosa or by Diplolepis eglanteriae on the leaves of the Dog-rose (Rosa canina). The galls are more likely to be seen than the adult wasps.Each gall is, in effect, a hollow, fleshy nursery chamber for a small white grub, the larva of the Diplolepis gall wasp, which feeds on the chamber wall. The galls appear to detach from the leaves before leaf fall and will lie in the leaf litter until the grub pupates and emerges as the small adult wasp in the Spring , only about 4 mm long.
