🐝 Ham or jam? What are the wasps choosing?
Researchers at UCL want pest professionals to help them understand what wasps are eating this summer 🍴
The Picnic Wasp Survey is looking at whether foraging wasps choose protein-rich foods such as meat, or sugary foods such as jam, fruit and soft drinks – and whether those preferences change as the season progresses.
🕵️ Pest technicians spend a lot of time observing wasps in the real world, so your sightings could provide particularly useful evidence.
Next time a wasp takes an interest in someone’s lunch, take a closer look before you shoo it away.
📸 Snap a photo if you can
🍖 Record protein, sugar or both
