On my travels, at the end of a journey, I would find an inspection of the front bumper and headlights of the car entomologically interesting.
Baetis Rhodani, iron blues and numerous other bugs some not identifiable except as a chromatographic smear.
In the last 5 years, despite travelling as many miles as usual, I've noticed a dramatic reduction in the rainbow smears on the car.
Are there simply less flying insects about? Has anybody else noticed this phenomenon? Should I just pour another glass of amarone and not worry about such things?
