Cleaver Heath Invertebrate Survey

The Tanyptera Trust is funding a 7.5 year project to promote the study and conservation of insects and other invertebrates in the Lancashire and Cheshire region of NW England. This project is hosted by National Museums Liverpool. Every year, the Trust runs an invertebrate recording day programme to bring together the invert recording community and increase the coverage of invert records on selected important and under-recorded sites.

On July 6th this year, the Trust organised a recording day at Cleaver Heath on the Wirral and a detailed species list obtained has recently been published and can be viewed on their website.

Summary of number of species by invertebrate order

48 species of spider (Araneae)

51 species of beetle (Coleoptera)

92 species of fly (Diptera)

38 species of true bug (Hemiptera)

18 species of bee/wasp/ant (Hymenoptera)

15 species of butterfly/moth (Lepidoptera)

2 species of centipede (Lithobiomorpha)

2 species of lacewing (Neuroptera)

1 species of harvestman (Opiliones)

1 species of grasshopper(Orthoptera)

1 species of booklouse (Psocoptera)

Notable records in terms of scarcity

Two flies, Helina ciliatocosta and Dolichopus virgultorum - New to VC58 (Cheshire)

A spider, Cheiracanthium virescens - Nationally scarce, only 3rd record for VC58 (Cheshire). On heathland, favours areas with short heather growth.

A true bug Alydus calcaratus  - Nationally scarce.  Very local distribution in the North West, only 3rd record for VC 58 (Cheshire),  one previous Wirral record on Thurstaston Common and  recorded on Cleaver this year prior to this event. Nymphs are ant-mimics and are often found in ant nests.

There were also six separate records of the impressive Emperor moth caterpillars (Saturnia pavonia) on heather and other plants.

Overall a very impressive list of species for a single recording day. Looking through the list, inverts associated with all the main vegetation types such as heather, gorse, wild flowers and birch/oak are evident as well as those found in the ground/litter layer. The former car park, now a nectar-rich wildflower area, was of particular interest for hoverflies and butterflies.

As a general rule regarding the management of lowland heathland for invertebrates, structural diversity across all the vegetation is important to support the greatest range of species and included in this would be the need to create and maintain a range of different age structures within the dominant plant species. These objectives are well accounted for within the Cleaver management plan and are also reflected practically in the work day tasks carried out by the volunteers.

Bumblebee Identification Session at Chester Zoo

RECORD are holding their first Drop In Session of the year at Chester Zoo next month.

Wednesday 12th February, 6.30- 9 pm

Mottershead Suite, Cedar House, Chester Zoo

Book your place on eventbrite here

We’ll have museum specimens, guides and microscopes on hand to use, so you can familiarise yourself with the bumblebees you are likely to encounter in Cheshire this year. If you’re new to invertebrate identification, we’ll help get you started and work together to understand what features to look out for. For anyone with an existing interest, it’s a great chance to find out some more detail about this group through practicing species identification in a friendly setting.

*Please note* This is not a formal workshop, just an opportunity to 'give it a go' along with other interested people in a shared learning environment.

These Drop-in Sessions are run in collaboration with the Tanyptera project.

Whilst each session will have a theme, you’re welcome to work on your own tasks making use of the RECORD/World Museum facilities. You can request museum reference specimens, equipment and literature in advance to help check identifications / practice with a particular group. Feel free to bring your own material too.

There is no need to be present for the whole session but if you would like to attend please book via eventbrite.

Email info@record-lrc.co.uk for more information or to request specimens or equipment for the session.

If you book on but can no longer attend, please cancel your place on eventbrite or by emailing us as soon as you can so that someone else can take your place.
