British insects, insect larvae, larvae on Guelder rose, larvae on Oak, Oak sawfly, Oak sawfly larvae, Viburnum beetle, Viburnum beetle larvae

Seeing these two different species of larvae was a good reminder to me that not all ‘caterpillars’ are butterflies or moths.

This first is the larva of an Oak sawfly (Periclista lineolata) that was happily munching away at a delicious young Oak leaf.

And these other little nibblers, above and below, covered in dots and dashes and munching on the leaves of Guelder rose, will grow up to be beetles, Viburnum beetles (Pyrrhalta viburni).

I doubt I’ll ever see the adult Oak sawfly, as they seem rather elusive, but I have more chance of spotting these beetles as adults so must remember to keep an eye out for them in July and August.

Viburnum beetles

British insects, Pyrrhalta viburni, viburnum, Viburnum beetle

If you’re a gardener who cultivates any of the viburnum species of plant for their frothy flowers, vibrant berries and heady scent, then you probably won’t be very keen on these little beetles as they can make a pretty good job of chewing up all the leaves on your viburnum shrubs, as you can see from my photos.

Rather unimaginatively but most accurately, they’re called Viburnum beetles (Pyrrhalta viburni) and, as a flat-living non-gardener, I find them rather cute. Both the voracious larvae (when they hatch in spring and early summer) and the less hungry adults (when they emerge from pupation in late summer) like to feed on viburnum leaves though it seems plants usually survive ‘even the most severe defoliation’. Personally, I think it would be best to enjoy the lacy appearance of the chewed leaves rather than resort to killing the beetles – all creatures have their place in the overall scheme of things, and the beetles won’t affect the stunning flowers and berries.
