WELLS, Maine (AP) – Scientists say they’ve found a species of butterfly in Maine 75 years after the last reported sighting in the state.

The state’s Inland Fisheries and Wildlife Department set out last summer to confirm one way or the other whether the spicebush swallowtail lived in Maine. Maine is at the northern end of the butterfly’s range, and the only documented Maine sighting was in 1934.

Wildlife biologist Phillip deMaynadier (dee-MAY-nah-dee-air) says the effort paid off in September when several occupied swallowtail nests were discovered in some hardwood swamps in Berwick and Wells. He says the finding provides proof that the butterfly breeds in Maine.
