I've been trying to grow Weld in my garden this year. First slugs devoured them, then some Geometrid larvae, and now Small White larvae are shredding them. Although the sources I've looked at so far don't mention Weld, it is related to Mignonette which is a known food plant.
A photo of a rosette of Weld, with long green shiny leaves. A number of green larvae can be seen eating the leaves.A close-up of a two larva eating a Weld leaf. The larvae are plain green with yellow spots in pairs along the side and a pale yellow dorsal stripe. Also present are two eggs - one is empty and translucent, the other is orange and yet to hatch.

The wonderful turbinate eyes of a male Cloeon dipterum that landing in my beating tray today.

"It's dark down here, has anyone got a light?"
The last seven segments of a glow-worm larva bent into an arch shape. The first few segments and the head can't be seen as they are pushed inside an old beetle hole in a thick piece of fallen conifer bark, where the larva is presumably looking for, or has found, a snail to eat. The larva wasn't moving and was underneath the fallen bark when I picked it up.  It is a rather contorted shape if it was only resting/hibernating?
