Anatrachyntis badia
(Hodges, 1962)
Florida Pink Scavenger
A small with a 9–10 mm wingspan, to the southern United States and to Europe and Hawaii. feed on decaying material, dried fruit, and , occasionally causing superficial damage to citrus rinds. First described by Ronald W. Hodges in 1962.

Identification
Distinguished from similar small Cosmopterigidae by its scavenger lifestyle and association with decaying fruit and debris rather than living plant tissue. The specific epithet 'badia' (Latin for ) may refer to coloration, but diagnostic characters require examination. In Europe, its presence indicates accidental importation rather than occurrence.

Habitat
Found in environments with abundant decaying material: fruit orchards, areas with fallen or drying fruit, and tropical greenhouses. In Germany, established in a zoological garden tropical greenhouse on bamboo infested with . Associated with fruit clusters, under sepals, and areas where develops.
Distribution
to southern United States (Florida to California, north to Maryland). to Europe: recorded from Italy, Greece, Spain, Malta, United , Poland, and Turkey via accidental importation in pomegranates; Germany (2011, tropical greenhouse). Also recorded from Hawaii.
Seasonality
active during summer when they may feed on ripe orange rinds. not specified in sources.
Diet
are scavengers: dry or decaying fruit, dead floral parts, , cones of Pinus , Cassia pods, dead peach and loquat fruits, lime, grapefruit, banana, cabbage, coconut blossoms, and elm leaves. Summer larvae may nibble ripe orange rind superficially without causing appreciable damage.

Life Cycle
with , , , and stages. Larvae are the primary feeding stage and have been observed living in colonies. Specific details on egg placement, sites, and time are not documented.
Behavior
are scavengers that feed in fruit clusters and under sepals where decaying material accumulates. In Germany, larvae were found living in colonies of the Palmicultor lumpurensis on bamboo, suggesting opportunistic use of microhabitats with accumulated matter. Feeding on ripe citrus is superficial and non-destructive.
Ecological Role
and scavenger, contributing to breakdown of dead material. Association with suggests role in in fruit cluster microenvironments.
Human Relevance
Minor economic significance: occasionally cause superficial damage to ripe oranges but this is not considered appreciable damage. Accidental introduction to Europe via imported pomegranates demonstrates potential for international transport in fruit shipments. Presence in tropical greenhouses indicates potential as greenhouse pest of minor concern.

Nomenclatural note
Originally described as Sathrobrota badia Hodges, 1962; transferred to Anatrachyntis. Listed on BugGuide as Pyroderces badia, reflecting historical placement.
European establishment
Not established in the wild in Europe; all records represent accidental importation with fruit, primarily pomegranates. The 2011 German record from a tropical greenhouse represents the only known breeding in Europe, associated with colonies rather than fruit.
