Species: Crematogaster ashmeadi

Taxonomic History (provided by Barry Bolton, 2013)

Distribution:

SE, north along the Mississippi to St. Louis

Biology:

Habitat: Dry-mesic to moist, remnant wooded areas, including those with highly degraded understory and ground layer, but whose old trees are still intact, also thickets and edges of old fields. Nests are in dead wood, often that of living woody plants.

Natural History: C. ashmeadi nests above ground and forages mostly in tree canopies and on lianas, in columns up and down tree trunks and vines to gain access to low vegetation. In Forest Park in St. Louis, the arboreal habitat of this species has allowed it to survive the depredations of Tetramorium tsushimae. Like all Crematogaster, this species feeds heavily on the secretions of extrafloral nectaries and honeydew-excreting hemipterans. Workers may also drink fluids from bird droppings on foliage, carrion and other protein-rich tidbits. Sexuals are reared in early summer.
