Lintneria eremitus is a butterfly ( moth ) from the family of moth (Sphingidae). The species was placedin the genus Lintneria Butler, 1876by Tuttle (2007) with a number of other species of the genus Sphinx .
features
The moths have a fore wing length of 27 to 37 millimeters. Their forewings have a yellowish-brown or gray-brown color on the upper side. The pattern consists of wavy lines, black lines and one or two small, white dots near the center of the Costa loader . The thorax is provided with golden hair. The medial area bears an extensive, dark brown spot, which several closely related species also have. The species is similar to Sphinx canadensis , but differs from this species in the bright discal spots that the similar species lacks. The hind wings are black on top with two white bands and a basal, triangular, black spot. The pattern is only slightly variable, but there are somewhat darker specimens.
The caterpillars are chocolate brown in the last instar and have seven pairs of brown, sloping side stripes. In the first stages, the caterpillars have a fleshy, horn-like appendage on the second segment of the thorax , which is replaced by a hump in the last stage. On the back, behind the thorax, there is a light spot that is cream-colored to pink-red in color and, as in all similar species, has a deep black core on the inside.
The doll is maroon and has a smooth surface. The exposed proboscis sheath is about 10 millimeters long and pressed tightly against the body. The cremaster is slim and ends in a sharp point.
Occurrence
The species is mainly found in the northeastern United States and around the Great Lakes and in two arm-shaped radiating areas south of it. The former encompasses the mountainous regions of the east and extends further south over the hill country of the Appalachian Mountains in the extreme northwest of South Carolina and west to Morgan County in Tennessee. The second arm runs on the eastern edge of the Great Plains with isolated records of the species in Wisconsin and Illinois, further south via Missouri and Arkansas to the isolated occurrence of individual finds in Louisiana. The species has only very rarely been detected between the two distribution arms. Evidence is missing from large parts of Kentucky and Tennessee and from Mississippi, Alabama, Georgia, and Florida. In the north of the Great Plains, the species is found in central Iowa, southeast North Dakota, and southwest Manitoba near Riding Mountain National Park . In Canada, the species is otherwise only distributed in a narrow strip along the border with the United States in southern Ontario and southwest Québec.
The animals mainly colonize more humid areas of water where the mint family (Lamiaceae) grow.
Way of life
You can observe the moths in the evening when you visit the flowers of phlox ( phlox ), tobacco ( Nicotiana ), Lonicera japonica , cultivated petunias ( Petunia ), common soapwort ( Saponaria officinalis ) and magnificent trumpet tree ( Catalpa speciosa ). The moths occasionally fly to light sources.
Flight and caterpillar times
The moths fly from late June to early August, presumably in just one generation.
Food of the caterpillars
The caterpillars feed different types of mint (Lamiaceae), such as mints ( Mentha ), Monarda species, sage ( Salvia ), Lycopis TYPES or Wild bergamot ( Monarda fistulosa ).
development
The females lay their eggs one by one on the leaves of the host plants. The nocturnal caterpillars are loners and hide at the base of the food plants during the day. Pupation takes place in a chamber several centimeters deep in the ground.
