While counting the Rosemary Beetles in our front garden yesterday, we now have 17 on Rosemary and Lavender, I came across the above insect. The elytra were deformed, there appearing to be bubbles in the surface. I had noticed deformed elytra in 2-Spot and Harlequin Ladybirds earlier in the year together with discolouration on Harlequin and 7-Spots. I believe this can be caused when insects emerge in cold weather but can it also be caused by damp conditions ?
