Oriental chestnut gall wasp was discovered in a woodland in Kent, England, in June 2015, the first time this pest has been confirmed as present in the UK. A second site has now been confirmed with the gall wasp present in a small number of sweet chestnut trees in a street in St Albans. Forestry Commission staff are investigating neighbouring woodland and trees to establish the extent of the outbreaks, and have taken swift appropriate action to fell and remove the affected trees.
A meeting of the Herts Invertebrate Project at Amwell Nature Reserve on 15 August 2015 found two species of Heteroptera that are believed to be new to Hertfordshire: Rhopalus parumpunctatus (pictured) and Nysius huttoni.
Remarkably, the bugs were found within minutes of each other, and in the same 10-metre square.

Hertfordshire Natural History Society members William Bishop and Joe Gray have just announced the launch of the Herts Invertebrate Project, an initiative that they are co-organising with the aim of promoting invertebrate recording at a variety of key sites across the county, especially looking at under-recorded species groups.

A visit to Amwell on Thursday June 25th 2015 led Graham Canny to the discovery of yet another new species of Odonata for the county - a Norfolk Hawker, also known as the Green-eyed Hawker, Anaciaeshna isosceles.
As if this wasn't enough, Graham then immediately followed this by photographing the second Scarce Chaser, Libellula fulva, to be recorded in Hertfordshire this year, a male this time.
This beautiful female Scarce Chaser, Libellula fulva was found and photographed by Barry Reed at Holycross Lake in Amwell NR on 5 June 2015.
This is a new species of dragonfly for Hertfordshire, the third in as many years.
