Total monthly rainfall: 54.5 millimetres. Maximum daily rainfall: 13 millimetres (7th February).

This fell as snow between the 7th and 10th, and there was 100% cloud cover for 17 days for at least part of each day.

Maximum temperature on the warmest days was 15°C on the 23rd,24th, and 25th. Maximum temperature on the coldest days was 0°C on the 8th,9th,10th, 11th, 12th, and 13th with overnight frost from the 7th to 14th when all ponds were partly or wholly frozen.

Total monthly rainfall: 149.5 millimetres.  Maximum daily rainfall: 25 millimetres (14th January)

Altogether there were 24 days when measurable rain fell, and 26 days with 100% cloud cover for at least part of the day. All ponds remained full throughout the month and woodland paths were frequently flooded, as were hollows in all the fields. This wet weather led to the development of fungus on many woodland trees.

Maximum temperature on the warmest day was 13°C on January 28th. Maximum temperature on the coldest day was 1°C on the 8th and 10th. There was overnight frost on 10 nights, and ponds and lake were partly or wholly frozen between the 7th and 10th and 24th/25th.

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!

Total monthly rainfall: 159.5 millimetres.  Maximum daily rainfall: 36 millimetres (4th Dec)

Altogether there were 19 days when measurable rain fell, and 17 days with 100% cloud cover for at least part of the day. There was an overnight gale on December 26th into the 27th which brought down many young trees, and caused all ponds to overflow.

Maximum temperature on the warmest day was 13°C on December 21st. Maximum temperature on the coldest day was 2°C on the 31st. 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. All ponds were thinly part-frozen on the 31st.
