These are incredibly skittish - always twitching, always flying away as you approach - but occasionally, they do stop and pause for whatever reason giving a chance to snap a few images. They do tend to re-visit the same part of the garden - usually around my variegated laurel. Pimpla rufipes is one of the Ichneumonidae but like many Ichneumon wasps it is badly under recorded.
