Explanation of Names
Anatrachyntis rileyi (Walsingham, 1882), formerly paced in the genus Pyroderces, is transferred to the genus Anatrachyntis following the treatment in Koster & Sinev (2003), Microlepidoptera of Europe, 5.(2)
Specific epithet in honor of Charles Valentine Riley (1843-1895), British-born American entomologist and artist.
Wingspan 11 mm. (1)
Adult - the wings are long, pointed and narrow. The hind margins of the wings have long fringes of scales much longer than the width of the wings. The terminal segment of the labial palp has three dark transverse bands. Some species in this genus may have a pecten of stiff spines on the scape of the antenna. (3)
The pink scavenger worm, has been reported in both Florida and California since 1926. It is also found in regions from Washington D.C. and Arkansas south to Florida, Texas, and southwestern Arizona. (4)
A general feeder in vegetable trash having been found in many legumes, aloe, banana, coffee beans, coffee cherries, castor bean, eggplant, milo, and many dried fruits. On citrus, the pink scavenger worm feeds on dry and decayed fruits mainly, but it also feeds occasionally on sound oranges and grapefruit. Generally, it consumes very little peel; but may eat through the rind and leave a hole which may be a source for secondary invasion by other organisms.
In Florida, the pink scavenger worm can be found among piles of purple scales and mealy bugs and is often present where fruit and leaves touch each other. It has been collected among black scales and even found beneath the female black scale cover. It also can be found feeding on the dead floral parts of orange blossoms. (4)
Life Cycle
During winter and spring months, the pink scavenger worm remains on the tree under scales or inside mummified fruit on the ground or in the tree. The moth is present in May through July. Eggs are deposited singly on the surface of a substrate. After a few days, the pinkish larvae with a black head hatch and move short distances feeding on any available debris. The full-grown larva pupates in a whitish cocoon among the frass where it has fed. The pupal period is about 2 weeks. (4)

P. rileyi is very similar to P. badia but can be separated by the color pattern on the hind leg. (4) See comments by Bob Patterson on this photo. (5)
