Bugs Count Survey results

In the OPAL Bugs Count Survey, our citizen scientists participate in three ‘challenges’ where they record as many invertebrates as possible on human-made surfaces, soft ground surfaces and taller plants within a specific timeframe. They also looked for six particular species of invertebrate.

What have we found?

 The data submitted by OPAL participants shows that:

  • More invertebrates were found on soft ground surfaces than on plants or human-made hard surfaces
  • Despite initially seeming inhospitable to invertebrates, human-made surfaces such as paving, fences and walls were heavily used by certain invertebrate groups such as ants, spiders and woodlice
  • Gardens were found to be associated with more invertebrates that feed on dead organic matter (particularly woodlice), parks and grasslands were associated with more pollinators, and woodlands were associated with more herbivores and predators
  • Nearly four times more small tortoiseshell butterflies were recorded in rural areas than in towns and cities. In contrast, tree bumblebees show a strong association with urban areas
