Appearance
"A. similis" is a solitary and phytophagous sawfly. This stale-blue sawfly has a length about 10 millimetres, with a hairy head. It has a dark-blue colour and its head is covered with short hair. Its face has two grooves on both sides, with a protruding comb in between. This comb divides in two at the end. The wings are brownish black, with blueish-black veins. The wings are without dots, which distinguishes it from its look-a-like, "Cibdela janthina".The species was described from four female samples which are part of the collection of the Natural History Museum, Leiden and collected by Philipp Franz von Siebold in Japan.
