Sabulodes aegrotata
Sabulodes aegrotata
Sabulodes aegrotata is a butterfly (moth ) from the family of the tensioner ( Geometridae ).
Features
The moths reach a forewing length 17-23 mm in males and 20-26 mm in females. The drawing and coloring of the species is variable, the type is the only Sabulodes - type that produces a melanistic form. In the male the coloration of head and vertex (vertex ) ranges from whitish to yellow-brown. The front of the head is narrow dorsal dark grayish yellow brown brown and pale ventrally. The coloration of the thorax varies from one color dorsally whitish to yellow-brown or ocher, ventrally it is white and in some specimens back yellow-brown or ocher. The abdomen is dorsally cream-colored or pale bleak equipped tawny and with some scattered brown or dark brown scales. Ventral abdomen is pale. The coloration of the head, thorax and abdomen similar Sabulodes caberata.
The colored forewings tops ranges from creamy white or pale yellow to ocher, brown or blackish brown in melanic specimens. The front wing is similar to drawing Sabulodes caberata in some specimens they may be absent. She is weak, the transverse lines are grayish brown and highlighted by brown spots on the veins. The fringe scales are either equally colored like the forewings or they have a brown spot next to the veins. The underwings are colored similarly as the tops and slightly pale. The drawing is missing or is designed as a clear dark brown area near the apex. The transverse lines are grayish brown.
The genital armature of the males is similar to that of Sabulodes caberata, but differs by the longer and more slender uncus. The Gnathos is provided with a smaller median bulge and a small bead. The Valven have an exposed Cost alarm which is bent at right angles, respectively. They are smooth and not provided with nodules. The Anellus is narrower at the front, the rear extension is especially rear wider. The aedeagus has a low posteroventrale bead, which is provided with three to 14 short, needle-like teeth. In some instances the teeth are arranged in two or three rows. The Vesica enough laterally when it is everted to the right. It is wide near the rear aedeagus and has small thickenings and a large posterior bulge with a small posterior sac. The Vesica tapers distally.
The genital armature of the females also similar to that of S. caberata and differs from it as follows: The lamella is postvaginalis 1.1 to 1.4 millimeters long. It is smaller and less in cross-section circular. It has either a rounded or tapered, pointed rear end. The sterigma is relatively long and narrow. It is concave rear and near the Lamella postvaginalis more or less wrinkled. The ductus bursae is shorter and about 1.0 to 1.1 millimeters long. It is narrower and back less thickened. The ductus seminalis arises from a clearly trained lobusförmigem bag on the left side of the ductus bursae. The corpus bursae is provided with a posteroventral länglicherem sclerotic band. The posterior Apophyses are 6.1 to 1.2 millimeters long.

Dissemination
Sabulodes aegrotata is native to the coastal regions in the west of North America. The range extends from the north-west of Baja California to north- west of Oregon.
Biology
The type is referred to in their area of distribution as omnivorous looper, because the caterpillars are found on a large number of plants and trees (except conifers). They have been detected in 27 plant families, agriculture delivers the kind of avocado, citrus plants and Genuine Walnut as a pest in appearance. The moths fly during the entire year.
