This page lists 3 insects and 8 ticks.
3 are nonnative.
Not every species: no complete official list of Alaska insects exists, so this page covers the ones state and Extension sources name. How lists are built.
Which insects can hurt you
Official sources single out these insects in Alaska, in their own words:
No official source we use states whether this animal is venomous. That does not mean it is harmless: do not handle it.
Size
Mature caterpillars 1.5 to 2.5 inches long (Missouri: up to 2 inches). Male moths about 1.5-inch wingspread; females larger, about 2 to 2.5 inches.
How to recognize it
Older caterpillars have a double row of five pairs of blue spots followed by six pairs of red spots down the back, and tufts of hair on each segment.
Spongy moth caterpillars do not make silk webs or tents.
Females are white and cannot fly; males are brown and fly erratically in daytime in July and August.
Where in Alaska
The Asian strain has been discovered in the U.S. and Canada recently, and a single male moth was found in a Fairbanks campground in 2006. Alaska Department of Fish and Game
