Description
Distribution
Ecology
Habitat
D. teres occurs in semi-shaded to open areas and well-drained sandy soil (FSU Herbarium). It can be found in longleaf pine savannas,[1] turkey oak sand ridges, mixed hardwood forests, exposed coastal dunes, coastal hammocks, and scrub hills (FSU Herbarium).
This species decreased significantly in response to clearcutting and thinning. This is evidence that Diodella teres prefers relatively undisturbed areas as to disturbed areas.[2] However, it still occurs in some disturbed habitats, including roadsides and railroad yards (FSU Herbarium).
Phenology
Flowering has been observed in June through October, and fruiting has been observed in June through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
This species has been found frequently burned areas, including annually burned pinelands (FSU Herbarium). It appears to benefit especially from high fire frequency (in the Osceola study plots)[3]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Diodia teres at Archbold Biological Station (Deyrup 2015):
Halictidae: Augochloropsis sumptuosa
Sphecidae: Prionyx thomae
Use by animals
It is an important food to bobwhites in the summer months.[4] The bee Augochloropsis suinptzosa was found on D. teres.[5]
