Plants appearing as if burnt as you pass. Burnt by sun or chemical. Looking to the underside of the leaves though they are shiny as if wet or lacquered but with tufts as if black insects stuck on while sticky. The leaves aren’t sticky however.
I thought some spray from roadside spraying may have burnt leaves, but some along the Wark Creek have the whole tree with dry leaves
This summer has seen a massive cohort or two of Xanthogaleruca luteola, and most elms in the town have been seriously defoliated (except for some of the variegated cultivars). Some nights there are thousands of dead beetles piled up outside lit shop windows, and I've had a steady stream of them inside my house.
