"Snow Mosquitoes" the First Wave of Summer Irritants
2012年4月11日 · But a lack of snow doesn’t effect the eggs of mosquitoes. Those eggs are the source of the smaller, faster mosquito species that hatch later in the summer. Mosquito eggs laid last fall will soon be floating atop standing bodies of water ranging in size from Wonder Lake to a water-filled moose track in the tundra.
How Mosquitoes Overwinter in Alaska | Geophysical Institute
5 天之前 · A few species of mosquitoes overwinter in either the larval or pupal stages. The largest of Alaskan mosquitoes, Culiseta Alaskaensis or the snow mosquito, overwinters as an adult under the snow, usually in leaf litter, beneath loose tree bark, or in dead tree stumps. This is the first species to emerge each spring, usually from mid- to late April.
Pound for pound, Alaska mosquitoes pack punch
2023年6月15日 · Alaska hosts at least 27 species of mosquito. The “snow mosquito” Culiseta alaskaeensis is a thumbnail-size insect that in autumn wafts down to the forest floor. There, it hibernates until its bunker warms in spring, when it ascends. By mid-June, the larger snow mosquitoes have lived out their few weeks of life.
Alaska mosquitoes spreading malaria in birds
2013年3月28日 · Because the malaria showed up in Alaska black-capped chickadees that don’t migrate, it proves that an Alaska mosquito was responsible for transmitting the tiny malaria parasite by sucking blood from an infected bird (probably a migrant) and pushing its infected proboscis into a local chickadee.
Aspen miners leave few leaves unturned - Geophysical Institute
2005年6月2日 · The bugs attacking Alaska’s aspens are tiny whitish moths as thin as pencil lead, so small that four of them could ride on the back of a mosquito. Those moths overwinter on the forest floor, emerge after the snow melts, and lay eggs on aspen buds when they pop from stems.
The Art of Mosquito-Swatting - Geophysical Institute
2024年12月19日 · The big, slow-moving early adults are relatively easy prey for an experienced mosquito- swatter, but they get smaller, faster, and meaner as summer comes on and the mosquito kids leave home. For years, I have tried to perfect the one-handed, mid-air grab, but succeed only occasionally.
Dragonfly earns state title; mosquitoes miffed
2008年7月2日 · It mauled the mosquito. It battered the butterfly. And it bested the bumblebee in a tight contest to be the Last Frontier’s official insect. Dragonflies, also known in some parts as mosquito hawks, horse stingers and devil's darning needles, dart through the Alaska air, tiny helicopters in search of mosquitoes and other prey.
Streaking, manmade lights in the sky | Geophysical Institute
2018年2月22日 · I slept outside a few nights ago. Lying a platform of packed snow, my face looking upward from the sleeping bag, I squinted at the Big Dipper. Within a few minutes, what appeared to be a moving star slanted across the dipper. Then another. And another. About 10 of them streaked through the Alaska flag in an hour.

Mosquito Zappers - Geophysical Institute
2025年1月9日 · It's impressive to watch the zapper in action. The fireworks, consisting of miniature lightning bolts about an inch long, and the satisfying and sizzling zap (there's no other word for it) produced when an errant mosquito wanders into the net are out of all proportion to the feeble 40 watts that the unit requires.
