Everywhere south of these localities, exceptin the immediate Gulf region, it abounds. In the East it is commonlyfound in New York City and Brooklyn, and at several points on Long-Island. In the Hudson River Valley region it has been recorded byFelt at Yonkers and Mount Vernon, and has been collected at New «In the main the bagworm is one of those characteristic forms like the wheel-bug(Arilus cristatus L.), the Carolina mantis (Stagmomantis Carolina L.), and the largerdigger wasp (Sphecius speciosus Dru.), true southern forms which are graduallyextending their northward range by following the seacoast or valleys, or, if carriedaccidentally northward upon railroad trains, establishing themselves at points beyondtheir former habitat.(Cir. 97)
