Common Name
No widely accepted common English name has been recorded for Iolaus fontainei; it is generally referred to by its scientific name.
Description
Iolaus fontainei is a small butterfly typical of the Lycaenidae family. Detailed morphological descriptions are limited in publicly accessible literature, but members of the genus Iolaus characteristically possess brightly colored dorsal wing surfaces—often shades of blue, green, or metallic hues—and comparatively muted ventral surfaces with fine patterning that aid in camouflage. The species' wing span is estimated to fall within the range of 25–35 mm, consistent with congeners.
Distribution
The species has been recorded in parts of Central and West Africa, specifically:
- Cameroon
- Nigeria (particularly the eastern regions)
- Possibly adjoining areas of the Republic of the Congo
These records are derived from entomological surveys and specimen collections housed in natural history museums.
Habitat
Iolaus fontainei inhabits tropical forest ecosystems, including:
- Primary and secondary lowland rainforests
- Forest edges and clearings where host plants are present
The butterfly is typically associated with forested environments that provide both nectar sources for adults and suitable larval host plants.
Biology and Ecology
- Larval Host Plants: While specific host plant records for I. fontainei are scarce, many Iolaus species' larvae feed on mistletoes (Loranthaceae) and other parasitic plants. It is plausible that I. fontainei follows a similar ecological pattern, but definitive confirmation is lacking.
- Adult Behavior: Adults are diurnal and are attracted to flowering plants for nectar. Observations suggest that they may engage in hilltopping—males gathering at elevated points to locate mates—a behavior documented in related Iolaus species.
- Ant Association: As with many Lycaenids, larvae may have mutualistic relationships with ants (myrmecophily), though specific ant associations for this species have not been documented.
Conservation Status
The International Union for Conservation of Nature (IUCN) has not evaluated Iolaus fontainei as of the latest assessment cycles. Consequently, its conservation status is officially listed as “Not Evaluated.” Habitat loss due to deforestation in its range could potentially impact populations, but empirical data on population trends are insufficient.

Notes
- Information regarding the precise morphology, larval host plants, and ant associations of Iolaus fontainei remains limited; further field studies are required to fill these knowledge gaps.
