Coptodisca sp. (Conocarpus erectus)
An undescribed species of Coptodisca ( Heliozelidae) that develops as a on Conocarpus erectus (button mangrove). The remains formally unnamed but has been documented from field collections. Heliozelid in this are characteristically small, with larvae that create distinctive blotch or serpentine mines in leaves. This species represents part of the poorly known Neotropical heliozelid fauna associated with coastal mangrove vegetation.

Identification
are minute with reduced wing venation typical of Heliozelidae. Larval mines on Conocarpus erectus leaves appear as pale, irregular blotches or short serpentine trails, often with deposited in discrete pellets or linear strings. Mines are initiated on the leaf upper surface. The can be distinguished from other Coptodisca by association with Conocarpus erectus and mine , though definitive identification requires rearing adults or molecular analysis due to the lack of formal description.
Habitat
Coastal and estuarine environments where Conocarpus erectus (button mangrove) grows, including mangrove swamps, tidal flats, and coastal hammocks.
Distribution
Range corresponds to that of plant Conocarpus erectus: coastal areas of South Florida, Caribbean islands, Mexico, Central America, and northern South America. Specific collection records exist from Florida.
Diet
Larva feeds internally in leaves of Conocarpus erectus, mining mesophyll tissue.
Host Associations
- Conocarpus erectus - obligate larval button mangrove
Life Cycle
Complete with leaf-mining larval stage. occurs within the mine or in a silken cocoon attached to leaf or substrate. pattern unknown.
Behavior
Larva feeds as a solitary , creating visible mines that may coalesce as they expand. are or with rapid, erratic typical of small .
Ecological Role
Herbivore that contributes to leaf damage in button mangrove stands; likely serves as prey for and other natural enemies.
Human Relevance
Potential minor pest in ornamental plantings of Conocarpus erectus; of scientific interest as an undescribed component of mangrove biodiversity.
