Insects of Cedar Creek
Order LEPIDOPTERA
Family PAPILIONIDAE
(Swallowtails)
The Swallowtails (35 NA spp, 3MN spp+) are a favorite among collectors.
The Tiger Swallowtail,
Pterourus
glaucus (Prunus+) is fairly common at Cedar Creek. Occasional
Black Morph females are encountered. The Black Swallowtail,
Papilio
polyxenes-asterius (Umbelliferae) is present but relatively
uncommon. Caterpillars of this species have been noted on Water Hemlock
(
Cicuta maculata). (The Giant Swallowtail, Heraclides cresphontes
occurs in SE Minn; and the Canadian form of P. glaucus canadensis occurs
in northern Minn.)
