Abstract

Neopamera bilobata (Say) is a wide-ranging, generalist seed predator that lives in the litter layer, but unlike many other species of Rhyparochromidae, it also ascends plants to feed on seeds. In Florida scrubs and other xeric plant communities in the southeastern United States, N. bilobata was found frequently, but irregularly, on female plants of Florida rosemary, Ceratiola ericoides (Ericaceae), from 2007 to 2016. This dioecious shrub flowers mainly in autumn and produces fleshy fruits and smaller, dry fruits that have been attributed to lack of pollination. Nymphs and adults of N. bilobata were collected from rosemary (31 sites) in Alabama, Florida, Georgia, Mississippi, and South Carolina. All nymphal instars were observed from mid-October to late April, suggesting that nymphs develop on the plant. The bug's seasonality on rosemary in the coastal plain of Georgia and peninsular scrubs of Florida varied from year to year and between nearby sites sampled the same day. A second rhyparochromid, the little-known ozophorine Ozophora trinotata Barber, was found at 13 sites in peninsular Florida and was syntopic with N. bilobata at 10 sites. Regardless of the presence of N. bilobata, nymphs (all instars) and adults of O. trinotata were found mainly on rosemary plants growing in the shade of oaks; in contrast, N. bilobata was found on plants in full sun. In the laboratory, nymphs of N. bilobata, when provided with both fruit types, fed mainly on fleshy fruits, whereas nymphs of O. trinotata fed mainly on dry fruits.
