features
Hochenwarth's gold owl is a butterfly from the subfamily of gold owls and, with a wingspan of 24 to 30 millimeters, is one of their smaller representatives. The forewings are colored in different shades of brown, have some distinctive lines and - as in many species of the subfamily Plusiinae - have a characteristic metallic markings on the forewings, in this case in the form of an elongated drop that is silver-white. The midfield and the wing tip are dark brown. The hind wings are yellow with a dark outer band. Similar species, which also have yellow hind wings and comparable markings, are Syngrapha devergens and the bog gold owl ( Syngrapha microgamma ). One can distinguish the species by the more jagged outline of the forewings in devergens , or the absence of such in microgamma . The larch gold owl ( Syngrapha ain ), which is also similar in drawing, is easy to distinguish due to its larger wingspan. The body of Syngrapha hochenwarthi is furry and has some tufts of hair. The trunk is well developed.
The caterpillars are red-brown in color. They have a yellowish back line and also colored side back lines and side stripes. The doll is black-brown. The cremaster is long, stem-shaped and has grooves.
