We have plenty of Red Valerian in the garden, a plant I like due to its ability to attract insects. I had noticed that a clump, by our front steps, was exhibiting a rose-coloured gall along some leaf edges, so investigated further. It is a fairly straightforward identification apparently - it is caused by Trioza centranthi (a species of Psyllid).
When looking at the above image on the computer, I noticed that there was an insect on the leaf that I had photographed. The resulting magnified crop is below. Could it be? Well, identifying the adults is meant to be tricky, way beyond my skill-set, but looking at images of adults on-line, this looks like a good match. Its presence on the food plant must count for something, if nothing more than a strong suggestion that this is, indeed, an adult
Trioza centranthi. An enjoyable lockdown interlude.
