pi-94 says >"(80% insect masses disappeared in the last 30 years in Europe)"<

Ha! Ha! A bunch of beekeepers do a study of their drunken bug counting over the past decades and, before you know it, someone concludes that "80% of Europe's bugs have disappeared"! That's rich!

FWIW enjoy your "missing insect masses" while you can because, if it's true, I guarantee that they'll be back in full force within two years (after all their predators die off) and shops will be selling out of insect sprays and repellants.
