description Euglossa dilemma Overview
The Euglossa dilemma is a species of orchid bee, specifically *Euglossa* spp., native to Florida. These bees are notable for their role in pollinating orchids and, more recently, due to their expansion as an invasive pollinator within the United States. They are particularly relevant to researchers studying insect pollination ecology and conservation efforts focused on managing non-native species impacts on ecosystems.
help Euglossa dilemma FAQ
Is Euglossa dilemma native to Florida?
No. It is a tropical American orchid bee that became established in southern Florida, where specimens were documented in Broward County in 2003.
Why was the Florida orchid bee originally called Euglossa viridissima?
The Florida population was initially identified as the visually similar Euglossa viridissima. Research published after its discovery separated Euglossa dilemma as a cryptic sibling species with differences including male mandibular teeth and fragrance biology.
Why do male Euglossa dilemma bees collect perfume?
Males gather volatile fragrances from flowers, fungi, and decaying material and store them in enlarged compartments in their hind legs. The resulting scent blend functions in courtship signaling rather than feeding larvae.
Does Euglossa dilemma need orchids to reproduce in Florida?
Apparently not. Florida populations have become established without the perfume orchids associated with orchid-bee pollination, because males can obtain fragrance compounds from other plants and environmental sources.
