They look like caterpillars of orange tip butterfly.they don't eat honeysuckle only members of cabbage family. They could have climbed your honeysuckle to pupate.

Try searching for Mother Shipton, which is a moth. The picture looks very much like it.

Pity to get rid of them - butterflies are up against it these days. Their main food plants are garlic mustard and hedge mustard so its unlikely that your garden plants will be in much danger from them.

I agree with you Stera. Why do all the questions start of finish with "how do I get rid of them"? Even if we don't like them they are part of the food chain for the birds, so best left if possible.

Unless they are cabbage whites on the brassicas....

Look interesting to me, l will look up both the Mother Shipton moth & the orange tip butterfly in my field guide.

I didn't mean these caterpillars were cabbage whites, (those are quite jazzy compared with these little plain ones)just that in my book not destroying caterpillars doesn't extend to cabbage whites on my brassicas lol.
