Kent Field Club Online Talks 2021

 
The Club will be hosting a series of online talks via Zoom over the next couple of months. The first of these will be on the evening of the 23rd February at 7.30pm and will be given by Steve Songhurst on the history of Vinters Park in Maidstone. 
 
If you are interested in attending, please log in to the website and register via the events page OR respond to the email that members will have received. The details of how to join the talk will be sent to you. You do not need to download Zoom to join the meeting - when you click on the invite, it will give you the option to view through your internet browser.
 
In each talk, attendees cameras and microphones will be muted but questions can be typed in the Chat box and will be asked to the speaker by the session moderator after the presentation. The talks will (hopefully) be recorded and eventually posted for the general public on our YouTube channel Kent Field Club - YouTube.
  
Subsequent talks will be on plant galls, bats and burying beetles, among other topics.  Further details will be communicated soon. The AGM this year will go ahead but will also be by Zoom.

A wasp new to the UK?

The solitary wasp Pemphredon austriaca (Kohl, 1888) is a species not currently recorded in the UK. It appears to have been increasing in the Netherlands in recent decades and there is a good chance that it could be overlooked in the UK.

This small, black wasp shows a preference for using Marble Galls, which are caused by the gall wasp Andricus kollari and found on oak. A. kollari emerges from these spherical galls, leaving small circular emergence holes. Other insects then take advantage of these chambers for shelter or nesting, including P. austriaca, which constructs nest cells within the gall.

February and March are the perfect months to collect some of these Marble Galls (where you can see the circular emergence holes) and provide something else to keep an eye out for on those familiar lockdown walk routes. Keep them in a plastic pot with some fine mesh or muslin secured over the top, or a specific mesh rearing container if you happen to have one, and make sure they are labelled with a location and the date collected. They should be kept as close to ambient temperature as possible, so a shed or covered area outside is ideal. The wasps are on the wing from May to August on the continent, so it’s worth starting to check the container every few days (or ideally daily) from mid-April to see if anything emerges.

If you are lucky enough to have some potential wasps emerge and are not sure how to identify them, get in touch with BWARS: https://www.bwars.com/content/bwars-contacts Happy hunting and fingers crossed for another wasp species to add to the UK list!

There were overnight frosts on December 1st, 2nd, 7th, 8th, 13th, 18th, 25th, and 28th to 31st. Most of these days also suffered from early fog and a cold wind-chill.

Noble Chafer Survey 2021

The noble chafer Gnorimus nobilis is a large metallic beetle which has been rare in Britain for the past century. The species is associated with traditional orchards and wood pasture where it's larvae feed on old, decaying wood within live trees.

In Britain, the species has been rare for the past century and is classified as ‘Vulnerable’, being a Biodiversity Action Plan (BAP) species. Traditional orchards are designated priority habitats but are increasingly being lost due to modern orchard management techniques or clearing of orchards for development.

Dr. Deborah Harvey of Royal Holloway, University of London has previously run a monitoring scheme for the species alongside the People's Trust for Endangered Species (PTES). She is now looking for volunteers for the 2021 season who would be prepared to deploy traps and lures in appropriate habitats and check them regularly in June this year.

If you are interested, please contact Deborah at .

Reminder: Your Field Notes Wanted for 2020 Bulletin!

 

Due to the cancellation of our field programme in 2020, there will unfortunately be none of the usual meeting reports to compile into this year's Bulletin. To make up for this, the Assistant Editor would be happy to receive any reports from members, whether from your house or garden, your local area or further afield in Kent. These can be accounts for specific sites and occasions or observations of notable species. If you are interested in contributing, please get in touch via the website.

 

The deadline for submissions is 15th February.
