Last evening I polished my car and when I went to it this morning there were several of the tiny creatures as depicted in my photographs. The shot is much magnified, the flies, if that is what they are, being only about 3-4 mm in length. What is intriguing is that they are all stuck down at the rear end and are unable to free themselves, in spite of their struggles. I would like to know what has happened here. Are they defecating or ovipositing and why have they become trapped by their own deposit? The car roof is warm but not hot and has a fresh coat of polish. My wife wondered if the high gloss has fooled them into mating with their own reflections. Any suggestions?
Both are non-biting midges (Chironomidae). They may have been attracted to the shing car mistaking it for a water surface. I do not know whether they defecate or try to oviposit, but either way if they try to do it on a shiny, hot car and do not do it quickly enough, the substance they excrete will dry and will thus glue them to the car surface.
