DISTRIBUTION:

Hylesia cedomnibus (wingspan: males: 41-46mm; females: probably larger) flies in
Peru: Loreto, Puno;
Ecuador: Sucumbios, Napo?;
Colombia: ;
Venezuela: Bolivar;
Surinam: Marowijne;
French Guiana: Camopi, Cayenne, Regina, Nancibo, Coralie; and
probably in Guyana: ; from sea level to 700m.

This species is very similar to H. metabus, but the forewing is slightly less rounded and the discal streak is narrower. The antennae are rusty yellow. The abdomen is yellow with some greyish hairs.

The forewing outer margin is straight. The markings are somewhat subdued on a dull mouse-grey-brown ground colour. The lines are concolourous and are bordered with dull greyish-white. There is a dull greyish white patch below the apex, and this same colour traces the lower 2/3 of the subterminal band.

In H. metabus the upper reaches of the pm line curve toward the body just below the costa, while in H. cedomnibus the pm line is straight. This feature and the others mentioned are not so easy to discern, especially from photos.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Specimens have been taken in April-May and in October-November, suggesting at least two generations annually. Larval hosts are unknown.

ECLOSION, SCENTING AND MATING:

Females extend a scent gland from the tip of the abdomen, and the night-flying males pick up and track the airbourne pheromone plume with their well-developed antennae.

EGGS, LARVAE, COCOONS AND PUPAE:

Eggs are probably deposited in clusters on hostplant foliage.

Hylesia cedomnibus larvae are probably highly gregarious and have the urticating spines typical of larvae from the Subfamily Hemileucinae.

Larval Food Plants

It is hoped that this alphabetical listing followed by the common name of the foodplant will prove useful. The list is not exhaustive. Experimenting with closely related foodplants is worthwhile.

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.

I do not know the origin of the genus name Hylesia.

I do not know the origin of the species name cedomnibus, but it may have to do with the gray colouration of the wings.
