Trichiotinus lunulatus

Distinguished from congeners by its smaller size and metallic green coloration. In Florida, it can be separated from the larger, Florida-endemic Trichiotinus rufobrunneus by size and geographic distribution patterns. The species is reliably identified by the combination of metallic green elytra and overall smaller stature relative to similar flower scarabs.

Found in dry oak/pine sandhill woodland habitats with grassy understory. Associated with flowering vegetation, particularly pricklypear cactus (Opuntia species).

Southeastern United States: Alabama, Florida, Georgia, Louisiana, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia.

Adults have been observed active in spring (April-May) in Florida, with activity likely extending through summer months when flowering host plants are available.

• Opuntia australis - flower visitorFlorida pricklypear cactus; adults observed on flowers
• Opuntia - flower visitorpricklypear cactus flowers

Adults visit flowers, particularly those of pricklypear cactus. Has been observed in mating pairs on flowers. Activity appears to be diurnal, with adults found on flowers during daylight hours.

Likely contributes to pollination of flowering host plants while feeding on pollen and nectar. Serves as prey for generalist insectivores.
