We have a new pest in town. An introduced one form China purportedly via a load of stones from China.
This one attacks most plants we grow. Favorite is the weedy Tree of Heaven, Ailanthus altissima
Images attached of the egg cases, first instar pest and newly developed trap that uses a pheromone lure to attract them into a container for disposal. I've seen them on Peonies, Grapes, apples, Pears and Quince.
Images of a trap recently developed using a pheromone lure based on Methyl salicylate, wintergreen.
Scanning Google the moths look like they'd be a pretty photo. As to the photos above, I would have appreciated a close up of the grubs - maybe we should have the forum tuned better as regards auto scaling down - photos seem a bit small.
Seemingly UK Border Force are on the look out, but it is not likely to do well here.

They were scaleld down photos. I'll get one in the morning a bit larger.
Arnold - so much worry went into having the forum auto-scale images - you can upload any size - has to be this way because most people have no idea about image sizes.
(Above I have come over all hyperbolic for some reason)

Couple of better photos with a macro lens. This is the first instar soon after hatching . The nymphs rushing up into the catch jar where a pheromone lure is placed.
They are highly reproductive in our environment.
Luckily only one generation per season
Hi Arnold, thanks for the macro shots, well worthwhile, they seem distinctive. Spotted grubs as well as spotted moths.
The last instar prior to becoming the moth is brightly colored red and black.
