Second county record of the Millipede Macrosternodesmus palicola

Only recorded as being new to Nottinghamshire in January 2016, when found at Pleasley Vale by Derek Whiteley, an example of this 4mm long millipede was found by Tim Sexton at Attenborough NR in early March.

Easily missed due to its size and usually found under large stones in the Winter and Spring, Tim recorded the county's second specimen, underneath some discarded concrete in the reserve's car park.

Some Atlas updates and two new pdf publications

We've recently produced updates and revisions to several pdf publications, including a second revision of our Atlas of Nottinghamshire Woodlice, following the discovery of five new species in the county list since 2015. The third edition of our Modern Atlas of Nottinghamshire Millipedes also features several new species which have been added in recent years. Both Atlases have species summaries and distribution maps updated.

Two new pdf files include a working checklist to Nottinghamshire Weevils, based on the records of local recorders and organisations and data extracted from the National Recording Scheme for Coleoptera: Curculionoidea, and following several requests to provide an up to date review of Nottinghamshire Dragonflies, we've gathered together the many records we have been sent, in an attempt to provide a reasonably accurate assessment online. This pdf looks at the status of the county's 27 known species of Dragonfly and Damselfly, with species summaries and distribution maps.
Confirmation of Colletes hederae being in Nottinghamshire

Adrian Dutton has recently confirmed that Colletes hederae (Schmidt & Westrich, 1993), is present in Nottinghamshire and has probably been here since 2016.

Adrian stated in an email that 'plenty of nesting activity occurred in a sandy bank at the Nottinghamshire Wildlife Trusts Skylarks Nature Reserve. Plenty in September 2017 and believe it was nesting there in 2016'.

The Millipede Leptoiulus belgicus found new to Nottinghamshire in February

Leptoiulus belgicus (Latzel, 1844) was new to Nottinghamshire on February, when found in a Mapperley garden. A Millipede with a distinct south-westerly distribution in the UK, largely occurring in South Wales, Devon and Cornwall, with few records from any counties of those.

Interestingly, it was also recorded new to the Sheffield area in late 2017 (per Richards, P.) and so searching of well established suburban gardens may well be productive.

Although not often an easy feature to see dependant on the lighting, the dark brown Leptoiulus belgicus has a distinct ID feature, in the form of a pale line running dorsally along its length.

A possible first record of Colletes hederae from Nottinghamshire

Yet more potentially interesting records have turned up within the large selection of invertebrate records sent to us in January. Among the Hymenoptera records is a single record of Colletes hederae (Schmidt & Westrich, 1993), which may be better known to some people as the Ivy Bee.

Colletes hederae has been spreading steadily north over a number of years and the NBN Atlas shows it has now reached Norfolk and north Wales. A Nottinghamshire record could well be likely within the next few years, but there was an unconfirmed report of Colletes hederae from Woodborough in September 2017.

2017 - A bumper year for records of the Western Conifer Seed Bug in Nottinghamshire

The Western Conifer Seed Bug Leptoglossus occidentalis (Heidemann, 1910) is a large Squashbug (Coreidae) of North American origin and generally regarded as being a serious pest of Pines, with Scot's Pine (Pinus sylvestris) and Douglas Fir (Pseudotsuga menziesii) being particularly prone to attack.

After being accidentally introduced into Italy in 1999, it spread rapidly across Europe and arrived in the UK as recently as 2007. It has since been widely recorded across the UK, south of a line extending from Liverpool to Newcastle-on-Tyne.

The speed of its range increase across the continent has been quite staggering, yet is similar to other invasive invertebrates that have reached the UK in recent years, such as the Harlequin Ladybird (Harmonia axyridis) and the Horse Chestnut Leaf Miner (Cameraria ohridella).

Nottinghamshire's first record was from Eakring in 2009 and it has been recorded annually since, apart from a blank year in 2013. Most records come during the late Summer and Autumn and largely seem to have come from urban areas. The last week of September (eight records) and the first week of October (six records) provide a clear peak in the county's known records.

In January 2018, we were given access to a number of invertebrate records held by the Nottinghamshire Biological and Geological Record Centre.

Among the records were a total of nine records for Leptoglossus occidentalis, which is considerably more than double the number of records from any previous years.

The 2017 records include single specimens at Stapleford (Chambers, S) on 24th August; Bramcote (Smart, G.) on 14th September; Sherwood Forest NNR (Turner, G.) on 18th September; Upper Saxondale (Cockayne, H.) on 24th September and at Highbury Vale (Watts, J.) on 28th September. Following these were records from Kirkby-in-Ashfield (Tarpey, L.) on 2nd October; Carlton (Skinner, M.) on 2nd October; Stapleford (Clarke, B.) on 23rd October and finally, a single at Cropwell Butler (Dulwich, P.) on 4th November.
A new first date for the Andromeda Lacebug in Nottinghamshire

The tiny Andromeda Lacebug Stephanitis takeyai (Drake and Maa, 1955) was originally thought to have been recorded as new to Nottinghamshire in August 2016, when a single specimen was swept from marginal vegetation at Attenborough NR (Sexton, T.).

This record seems to have been beaten though, as among a large number of invertebrate records sent to us by the Nottingham Biological and Geological Record Centre, was an earlier record of Stephanitis takeyai from New Balderton, Newark on July 3rd 2015, beating the Attenborough record by just over a year. There are further records of Stephanitis takeyai from Market Warsop in August 2017 (Pendleton, T.A. and Pendleton, D.T.) and from Attenborough village (Sexton, T.) in September 2017, suggesting that it is probably well established in the county.

A belated record of Nemapogon variatella for Nottinghamshire

Among a large number of lepidoptera records sent to us by the Nottingham Biological and Geological Record Centre in January, was a record of Nemapogon variatella (Clemens, 1859) from Clumber Park in 2004.

The moth was recorded by Andy Godfrey and it seems to have been unrecorded in Nottinghamshire previously and we know of no other records since. Possibly having two generations a year, the adult occurs between March and August and closely  resembles Nemapogon cloacella, but with slightly narrower wings and a whiter head. The larvae feed on bracket fungus and possibly on grain and stored produce.
