Observations of Isodontia mexicana in the United Kingdom
The first time I saw this wasp was on 27 August 2022, in the Herb Garden in Battersea Park. https://uk.inaturalist.org/observations/132809120 . It was on Goldenrod (Solidago}. The next day I saw it again but I did not manage to get a photo.
I saw it again 2 weeks later, on 10 September 2022, and this time I was able to take better photos. https://uk.inaturalist.org/observations/134427963
The first sighting in the United Kingdom, in Greenwich, SE London, had been in August 2016.
