The extremely elongated proboscis of the genus Prosoeca (Nemestrinidae) evolved as an adaptation to feeding from long, tubular flowers. According to the functional constraint hypothesis, nectar uptake through a disproportionately elongated, straw-like proboscis increases flower handling time and ...

They favor flowers with the highest sugar content (often red-colored and tubular-shaped) and seek out, and aggressively protect, those areas containing flowers with high-energy nectar. They use their long, extendible, straw-like tongues to retrieve the nectar while hovering with their tails cocked...
The tubular siphon as in kalligrammatids is also not found in these species. Instead, the prolonged elements of mouthparts in the material we examined are distinctly separate distally. In Fiaponeura gen. nov. the long blade-like lobe is slightly curved along the outer margin; it is equipped...
