Features
The moths have a forewing length of 40-46 millimeters. You see Ceratomia undulosa similar. Only fresh specimens have a greenish tinge. Ceratomia hageni has as well as the similar style Diskalfleck a white and a white hem at the forewing outer margin, but the white medial line is missing. Instead, it has a dark medial line, with the addition of Submarginalbereich and the wing tip are drawn white. The front edge of the forewing is more brown in some individuals. The upper side of the hind wings is dark gray -brown with paler gray at the base and on the outer edge.
The caterpillars have in the last stage a green to brown color. They are small white points are awarded, so that the body acts rough. There are seven oblique stripes that extend from the front to the back of a segment of the next segment on the sides. The strips are very flexible towards margins back to purple. The pretty granular Analhorn is almost white.
The doll has similarity with that of Ceratomia sonorensis. It is light brown and has a smooth, shiny surface. On the sixth and seventh segment can be seen grooves for the stigmata. The proboscis sheath is completely overgrown. The short, wide cremaster ends in a rather blunt twin tip.
Occurrence
The species is distributed mainly to the rivers of the Ohio River Valley and the Mississippi River valley in the center of the United States. North reaches the circulation in the Southwestern Ohio and includes large parts of Indiana and extreme southwest Michigan and Wisconsin one. In the south, there is anecdotal evidence from Tennessee, the extreme northeast Georgia and the Gulf States. To the west is the type in eastern Nebraska, distributed in Kansas, Oklahoma and Texas and there too often ..
Ceratomia hageni apparently settled exclusively deciduous forests close to watercourses.
Way of life
The moths fly at night to light sources. Whether to record the moths food, is not known.
Flight times and caterpillars
Flight times and of generations of moths are not fully known. In Michigan, the species seems to fly until early September in just one generation in late summer from mid-July. In Indiana and Illinois, most design is carried out in June and July, but some are still of August and beginning of September known. Whether formed more than one generation per year here, is unknown. Further south, flying the type in the Mississippi River Valley from April to September in at least two, possibly three generations.
Food of the caterpillars
The caterpillars feed on apparently solely from the leaves of the milk orange tree ( Maclura pomifera ).
Development
The females lay their eggs in small Situated 4-12 piece on the leaf undersides of the caterpillar food plants from. The caterpillars live during the first two stages sociable, from the third stage, they begin to divide and eventually live in the last stage solitary. In the quiescent phases, the caterpillars often move back to the trunk of the trees and hide in crevices of the bark. They will eat, however. At the young leaves at the ends of the branches Older caterpillars let themselves fall in disorder from the tree and sit motionless on the ground. Pupation takes place in a chamber several inches deep in the ground.
