Walking in England’s New Forest in 1892, butterfly collector S. G. Castle Russell encountered such numbers of the insects that they “were so thick that I could hardly see ahead”. On another occasion, he “captured a hundred purple hairstreaks” with two sweeps of his net.

Patrick Barkham, who recounts these riots of nature in his 2010 book on butterflies, laments never seeing such a sight. However, new research suggests Barkham is a rarity, because a lot of people are forgetting, or just don’t appreciate, how much wildlife there was.

To gauge this effect, Lizzie Jones at Royal Holloway, University of London, compared population records dating back to 1966 of 10 UK bird species against public perceptions of those birds. More than 900 people told her how abundant they thought the species – including declining ones such as house sparrows – were today and when they were aged 18.

Is it that there are actually fewer bugs, or do the more aerodynamic cars of today cause fewer dead bugs to stick to bumpers/grills/windshields?

It's actually the opposite - more aerodynamic means a smaller cushion of air, which should translate to hitting more bugs because they aren't pushed out of the way as strongly or for as long. Instead, insect populations have fallen so dramatically that this effect still doesn't make up for it.
