Thank you to those who took part in the 2 years of the Big Wasp Survey. We are delighted by the level of interest and enthusiasm across the whole of the UK to get involved and contribute. Thousands of you embraced the Big Wasp Survey, providing a snapshot of the life of one of our most vital but poorly understood group of insects in one of the most important habitats in the UK – our gardens.
Despite the poor weather in 2017, we received 6,680 wasps from 1,294 people across the UK. A fantastic response, providing a wealth of information comparable with specialist recording data collected over decades.
We are still processing the 2018 trap submissions.
The majority of the wasps were our common wasp, Vespula vulgaris, the German wasp Vespula germanica and the European hornet Vespa crabro, which together made up almost 95% of those collected. All the wasps were workers nearing the end of their life cycle, so the survey had no impact on queens preparing to hibernate and produce the next year’s colonies. We were also reassured not to receive the invasive Asian hornet Vespa velutina, despite two reported sightings in 2017.
We’re particularly interested to understand the impact that 2018’s hot summer had on our wasp population and we are still processing the results.
