brrr it’s been cold! i mean, what good is it when it gets this cold?
LET ME TELL YOU.
with the extended cold we had, it’s possible that those invasive insects could’ve been wiped out.
but first, a list of invasive terrestrial “animals” in minnesota:
first, let’s talk about the emerald ash borer, since it seems to be one of the big bad bugs i keep hearing about. it’s the reason you can’t bring firewood with you to campgrounds and have to pay $5 for 3 logs.
temps need to get to -20º to begin to kill the borer, and at that point, about 50% of them die. around -30º is when 90% of them will die. i think we can safely say sayanora to at least 50% of the EAB larvae in the state, more like 90%.
another bug that i would probably run away from, the gypsy moth, would suffer from some cold. temps of -20º that lasts 48-72 hours kills exposed eggs, and alternate freezing and thawing in springtime can prevent hatching. i think we may have hit that -20 (or close to it).
in other entomological news, the beetle epidemic that was sweeping the black hills is over!
and while the bugs won’t be gone forever – they will eventually migrate back – this summer will give the people who manage invasive species time to implement a containment plan and basically start with a clean slate.
and since we’re talking entomology, let’s end with some etymology.
the word bug was formed in the early 1600s from the word bugge (beetle) which grew from two words: bugge/bugja/bogge and budde/budda/buddo.
bugge was a word for a hogoblin, bugja meant swolen up, and bogge meant snot. budde was beetle, budda was a dung beetle, and buddo means a louse/grub. sounds like they just took a bunch of gross things and smashed them into one word.
