I expect the female bugs are attracted to the warmth of the Solar Edge Power Optimizers to incubate their eggs.

its like little mites, they get attracted to the warm circuitry, and also they seem to like the type of oil that gets sprayed onto finished circuit boards as a protectant (to stop IC pins from corroding) in the factory, as the old laquer they used to spray on (like clear varnish) got phased out due to chemical nasties....
you can get these going into your mobile phone as well if you keep it in the car or van and they end up running around on your screen which is not nice.......can I borrow your phone.....Sure.....EEEEEEKKK BEESTIES!!!!
