Invertebrate Surveys

As a teenager I used to hear older naturalists comment frequently that there used to be a lot more glow-worms back in their day. Nowadays I find myself saying the same thing.

Alongside the footpaths, back lanes and disused railway lines of north Devon I would often pass the green glow of the females in the grassland and low scrub.

While some invertebrates are generalists, and feed on or live in a wide variety of trees, many can only be found on certain species, or a very small number of species. Sometimes the name is a dead giveaway – oak apple gall wasps, the blue willow beetle etc. But some can be somewhat inaccurate – for instance the oak eggar moth does not feed on oaks, but gets its name due to the cocoon resembling an acorn.

Five years ago this month, on an otherwise mundane day in the ecology lab at the University of Bristol identifying money spiders, smaller ground beetles and other invertebrates, I was informed by two undergraduates that they had found three “fat” black beetles in their pitfall traps in Bristol. Several species came to mind, including churchyard beetles, bloody-nosed beetles and some of the larger ground beetles such as the violet ground beetle.

Ecosulis entered a staged tender process and was appointed through the Framework for CSM SSSI Invertebrate Assemblage Assessments by Natural England to undertake condition assessment for invertebrate assemblages as Sites of Special Scientific Interest (SSSI) features across 27 SSSIs around the UK. The contract commenced in April 2012 and is currently ongoing.
