Mini habitats – Hawthorn snag -Wandlebury NR

Amazing what you can find in a small habitat the Osmia caerulescens is the host for the Sapyga-quinquepunctata  and the blue wasp is looking for its host which is a type of wasp which I did see but failed to photograph. Sometimes its worth looking in a smaller area than walking for a mile and trying to look for that needle in a haystack.
