I'm posting this photo on behalf of the photographer, Wendy Wilson. It's of a Nationally Scarce species that preys on Lepidoptera caterpillars and is said to spend most of its time in the tree canopy, so I suspect that few people will have observed it egg-laying, as shown here in Wendy's photo.

Wendy says:
"While in Black Park on Good Friday, I checked briefly for Purple Hairstreak caterpillars on an oak tree. Instead of a PH larva, I saw a beetle I didn't recognise and took a hasty photo before it flew off and I could go for a decent close-up. When I got it up on the screen, I could see it was laying an egg. It's rather an exposed place for an egg, being on top of a leaf in full sun. I have identified it as Dendroxena quadrimaculata, a carnivorous species of the Silphidae family (unless anyone knows better). It eats larvae of lepidoptera which it tracks down by scent (note its clubbed antennae)."
