In the area of Europe where the moth has been introduced, the damage is very serious because natural regulation does not occur at a significant level. However, in European areas where the Asian hornet ( Vespa velutina) is present prior to the introduction of C. perspectalis, some degree of predation by the wasp is observed (not confirmed by scientific and clear results). This is namely in the south-west of France, the first place where V. velutina was introduced to Europe in 2004 ( C. perspectalis invaded this area in 2012). V. velutina is able to capture small larvae, and larvae preparing for the nymphosis in their cocoon.

I made my clear top from 1mm polycarbonate, which is a highly flexible clear plastic and quite pricey alas. Just google for it and there are plenty of plastic suppliers around. Buy a sheet 2 metres by 1 metre and you'll have more than enough. My clear top sits inside a rim round the tub made from 3cm trunking (white plastic used to cover ugly cables) and is attached with screws and washers all the way round. It may take a couple of attempts to get the clear top right and you might want to map it out and use some spare material or cardboard first to make a template to cut the polycarbonate against.
