Xylophanes bilineata (wingspan: males: 74-78mm; females: ??) flies in Peru: Chanchamayo; Cusco.

The dull grey-green forewings have a produced apex. The outer margin is slightly hollowed out below the apex, but then becomes quite convex. The cell spot is a relatively large black dot followed by a small slightly darker area. The very straight first and fourth pm lines are evident, the fourth being only slightly preapical and the most pronounced. Internal pm lines are vestigial. The final line is inwardly scaloped and marked with dark dots on the veins.

The hindwing is grey-black with a faint orangey-cream band and a narrow dark green outer margin. The fringes are white with some dark intrusions along the veins.

"Extremely similar to Xylophanes fassli but darker green oval patch distal to the discal spot even smaller." CATE

Xylophanes bilineata probably broods continuously.


Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

Females call in the males with a pheromone released from a gland at the tip of the abdomen.


Larvae possibly feed on Psychotria panamensis and Psychotria nervosa of the Rubiaceae family and on Pavonia guanacastensis of the Malvaceae family.

Moths emerge approximately one-two months after larvae pupate.

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

Jean Marie Cadiou writes, "When I say "Xylophanes" in English I pronounce it something like "Zailophanees", with the emphasis on the "o". The French pronounce it differently, something like "Kzeelophaness" with no emphasis, and the Germans yet in a different way..."

In Greek myth, Phanes is the golden winged Primordial Being who was hatched from the shining Cosmic Egg that was the source of the universe. He personifies light emerging from chaos.

"Xylo" is the Greek word for wood.

The specimen type for the genus Xylophanes is Xylophanes anubus. Perhaps ? when Hubner examined this species, the yellow-orange and brown tones of the forewings suggested wings of wood.

The species name "bilineata" probably refers to the two prominent pm lines.
