Entomology and ecologist. Currently a post doctoral research associate at the University of Oxford. Interested in wasps, bees, species ID, biodiversity monitoring and pollination ecology.

We have Andrena cineraria nesting in the lawn of our new house. Only the second bee species recorded from the garden so far, but hopefully many more will find a home here as we begin to improve our small garden for wildlife. 🐝

It was really nice to find Brown Hairstreak eggs at the Begbroke site last week. This species has declined due to hedgerow removal and annual flailing. The site offers promising potential for hedgerow/habitat enhancement alongside the development that could support this somewhat elusive butterfly.

Lots of Holly Blue, Celastrina argiolus, around the ivy at the moment. The spring generation primarily uses holly, whereas the summer generation switch to ivy. One of the many beautiful species supported by this underrated plant!

Many people have noticed the abundance of 7-spot ladybird in the UK this summer. I wonder if there will also be a related boom in Ladybird Parasitoid Wasp, Dinocampus coccinellae? It turns the host beetle into a 'zombie' bodyguard, standing guard over the developing wasp pupa.

Lovely (albeit wet) day in the field yesterday, establishing a sampling programme to measure a biodiversity baseline at Begbroke Innovation District. However recent heavy rain had flooded several pitfall traps!
