Description
Butterfly
The moths reach a wingspan of 53-90 millimeters. Its basic color is yellow. On the fore wings are four broad black stripes. From deep black hem, a number of yellow dots takes off. On the hind wings, a long narrow black stripes and a black Diskoidalader also be seen. From the dark fringe region, four large yellow spots stand out. At the apex is sometimes a reddish stain. The seam area is generally characterized by bruises and at Thomus by a red spot and a long tail.
Very rarely occur almost monochrome black moths. This is exclusively for females.
Caterpillar
Adults caterpillars are green, thickened at the front part and show a yellow bead, a bright dot row and two large, dark, yellow -bordered and blue- cored eye spots. Younger caterpillars are similar in appearance white brown bird droppings, which they are camouflaged from predators.
Similar Species
Papilio canadensis was only in the year 1991 by Hagen et al. recognized due to physiological and genetic differences as an independent species and cleaved from Papilio glaucus (Eastern Tiger Swallowtail ). Animals from the north and the west of North America are safe as P. canadensis to address, such as P. glaucus from the southeast. In the northeastern region of overlap, both species occur. There are also hybrid forms. External distinguishing features are difficult to discern. In these cases, specialists should be held to determine rate.
Distribution and habitat
Papilio canadensis is east of Alaska in a wide belt across Canada, to the east coast before, but missing on Labrador. In the U.S., some northern states are populated. Main habitat are deciduous forests, clearings and forest edges.
Way of life
It makes one generation a year, flying their Falter May to July. These like to visit flowers for nectar intake. They can be found for receiving liquid and minerals sometimes in the number of damp places. The caterpillars feed on the leaves of a variety of plants, especially of birch (Betula ), apples (Malus ) and poplars (Populus ). They like to hide in silk threads spun with leaves. The pupae overwinter.
