Here is a third instar Volucella inanis larva emerging from gyne comb in a Vespula vulgaris nest! You’re welcome!

No stings! The brood parasite numbers are looking pretty poor so far. No sign of any of my “big three” in this one. The absence of overwintering stages indicates that the hoverflies are behind compared w/ previous seasons. May need to push back my departure so I don’t go home empty handed. 😬

Here is a first person view (fpv?) of the first stages of collecting a pretty frisky German wasp nest from yesterday.

German and common wasps are still after protein here in Silwood Park! @waspwoman.bsky.social @cintiaoi.bsky.social

Does anyone in the South of England have a wasp nest in their garden they would wish removed anytime in the next five weeks? This research led by Dr Bob Brown @dr-bob-brown.bsky.social, is helping with control of invasive wasps in New Zealand.
