Photos of Mining Bees on Troopers Hill >>

Brief summaries and links to the reports of invertebrate surveys carried out on the hill appear below, there are also photographs showing some of the moths (note these were taken on other sites).

Bristol & Moth Group - 19th May 2017

It wasn't an ideal night for moths, but as darkness fell the traps attracted a steady flow of flying visitors. 31 different spieces of moths were recorded "nothing earth-shattering but respectable given the cool breeze".

This event was open to the public and some photographs can be seen here.

Bee Survey - July 2015

"It was great to visit a site which is so obviously valued and actively conserved"

David Notton, Senior Curator (Hymenoptera) from the Natural History Museum visited Troopers Hill along with other sites in Bristol to carry out a DEFRA sponsored survey of bees to provide a publicly accessible reference for identification using rapid DNA techniques. David found 4 bees that we think have not been recorded before on Troopers Hill, his full list recorded over two visits in early July is mainly bees but includes a few other inverts which he could easily identify or appeared important.

The 4 new bee species are
• Ceratina cyanea (blue carpenter bee)
• Hylaeus dilatatus (chalk yellow face)
• Lasioglossum smeathmanellum (Smeathman's furrow bee)
• Nomada flavopicta (Blunthorn nomad)


David Notton Bee Survey Results - July 2015

Updated list of over 70 species of bees recorded on Troopers Hill

Bristol & Moth Group Field Meeting - 18th July 2014

Good numbers of P. xylostella but no other migrants. The Nationally Notable plume moth G. ochrodactyla was netted at dusk around its foodplant Tansy by RH. True Lover’s Knot presumably feeds on the heather growing on the site.

This event was open to the public and some photographs can be seen here.

David Gibbs 2007 Invertebrate Survey

This survey was funded as part of our Big Lottery Breathing Places Project. David Gibbs completed the invertebrate survey with site visits on on 19 April, 24 May, 19 June & 18 July. The four visits of yielded 262 species of which 30 are considered to be of conservation significance and 6 have RDB or equivalent status. This was excellent news and confirms that Troopers Hill is one of the best sites for invertebrates in the area.

Bristol & District Moth Group Field Meeting - 26th May 2006

Nothing unusual was found this year, but each survey adds to our knowledge of the reserve. Again this event was open to the public and some photographs can be seen on our events page.

David Gibbs 2006 Invertebrate Survey

This survey was funded by Bristol Parks.

Report Summary:

Of the 276 species found, 23 of them are considered to be of conservation significance. This is a proportion of 8.3% which places Troopes Hill amongst the most important reserves in the region. Five of the species found (1.8%) have RDB or equivalent status, further confirming the importance of the site.

Bristol Naturalists’ Society Invertebrate Section Field Meeting - 2nd July 2005

This was one of Bristol Naturalists' regular field meetings and we are pleased they chose to visit Troopers Hill this year.

The Full Report includes lists of species found.

Report Summary:

Examples of the bristletail Dilta sp. were common, swept from low growing dense vegetation. Specimens were not taken for identification but many were light orange in colouration. The bug Myrmus miriformis, although not uncommon, is restricted to quality grassland sites. Sitochroa verticalis is a local moth of “waste land” although sometimes reinforced by immigration. The click beetle P. tesselatum is very local in the region, only known from a few other sites in “Avon” eg Gordano Valley. The Kidney-spot Ladybird is widespread but local although probably under-recorded as it is found mainly on trees. The Leaf Beetle Cryptocephalus aureolus is Nationally Notable (Nb) and very local in the region (also recorded by Dave Gibbs in 2000).

Bristol & District Moth Group Field Meeting - 18th June 2005

This event was part of our Evening Moth Hunt (see our Events page for photos). As well as entertaining local people of all ages late into the night the main aim was to record the different species of moth present on the hill. Three moth traps were set, their bright lights attracted the moths which were then identified. Some were caught in sample tubes for closer examination but all were then released unharmed. We believe that this was the first time moth traps had been set on the hill and we hope that it will not be the last. Regular monitoring of different species over time will tell us whether our management of the hill is succeeding in maintaining (or increasing) the range of species present.

The full report on the evening includes a list of all 92 moths found. Six photographs of these moths are shown below and these are highlighted in blue on the list. The most interesting macro-moth of the night was probably the Red-necked Footman which occurs locally across the region in woodland and occasionally appears as a migrant. The larvae feed on lichens growing on deciduous trees.

David Gibbs 2000 Invertebrate Survey

This survey was funded by Bristol Parks.

Report Summary:

- 137 species found, a good diversity for a site of this type and size

- 13 Nationally Scarce and RDB species identified, 9.5% of total, higher than all but the very best sites in the region

- the endangered RDB1 nomad bee Nomada guttulata found

- the site pre-eminently important for the Hymenoptera

- bare ground caused by erosion very important for nesting bees and wasps

- broom and gorse support very scarce insects
