BEES, HORNETS & WASPS:
Bees, hornets and wasps are largely beneficial to the environment--as pollinators of plants, and in many cases as predators of agricultural and other insect pests--but sometimes they can become a problem and a health concern for homeowners.

 Non-Native / Rarely Found in Maine:

Black Widow: Click to see a photo of a Black Widow spiderhtml || pdf.(Ohio State Univ.)
[Non-native, but sometimes hitches a ride into Maine via packages, cargo, etc.--most often via shipments of produce from out-of-state; The Northern Black Widow, however, may be an infrequent inhabitant as far north as central Maine.]
Brown Recluse (Non-native, and thus extremely rare in Maine--only possible if brought in from out-of-state): html || pdf (Ohio State Univ.) (includes photo) (US Distribution Map)
NOTE: People have varying sensitivity to spider bites. In rare cases, some individuals with highly sensitive or weakened immune systems may have a significant to severe reaction to a bite from an otherwise nonpoisonous spider, and there are many spiders that homeowners mistakenly suspect to be the Brown Recluse. Misdiagnoses are thus very common.
