Crocozona coecias  HEWITSON, 1866
subfamily - RIODININAE

There are more than 1150 species of Riodinidae in the neotropical region, but far fewer elsewhere in the world. Many Riodinids have bands of red or orange, or are peppered with metallic silver, blue or green scales, hence the popular name of metalmarks.
The genus Crocozona comprises of 4 species. Two of these, fasciata and pheretima are marked with broad orange bands on the forewings only. The others - coecias and croceifasciata, have narrower bands on both fore and hindwings. 
Crocozona coecias produces 2 subspecies - arcuata which occurs north of the equator in Colombia, Venezuela, Surinam, Ecuador and Guyana; and coecias which is found in Peru and Bolivia. The band on the forewing is more strongly incurved in arcuata. The insects illustrated here are from central Peru and are intermediate in appearance between arcuata and coecias.

This species occurs in disturbed rainforest habitats at elevations between about 200- 1800m. It is usually seen along roadsides, riverbanks, wide forest tracks or other semi-open habitats.
This appears to be unrecorded.

Adult behaviour

This sun-loving little Riodinid can often be found in two's and three's basking on ferns or other low foliage in open, forested habitats. It has a rapid twisting flight that is difficult to follow, but it usually resettles only a short distance from it's original position. 

The butterfly does not appear to visit flowers, or to imbibe moisture from the ground, so it's feeding habits remain a mystery.

In very hot weather, or when there is a threat of rain, the butterflies hide beneath the leaves of bushes or low growing herbage, with wings outspread.
