Potamanaxas flavofasciata, the yellowbanded skipper, is a butterfly in the family Hesperiidae. It is found in Ecuador, Peru[1] and Bolivia.
The upper wings are mostly dark brown, while a wide, golden-yellow band crosses the forewing. A small white patch may be seen near the forewing apex. Additionally, the fore and hind wings have a narrow border checkered with yellow and brown. The underwing is similar except it is somewhat paler due to the lack of sunlight received in the area. The hindwing beneath is a dark brown with multiple bands of darker brown. Only males have a white ring below the antennal clubs.[2]
Laid by females, eggs are usually found as a short string of 2-7 red-colored eggs. They are stacked at angles instead to of being centered on each other.[3]
Caterpillars have small yellow dots and are colored yellow-green. It has a wide, yellow, lateral stripe. The head is reddish-brown with two false eyespots in the lower facial region.[4]
The chrysalis is covered in a white, granular substance but is generally brown with a green hue.[5]
