of Virginia Waterleaf
Hydrophyllum virginianum (Virginia Waterleaf)
(Bees suck nectar and/or collect pollen, flies suck nectar or feed on pollen, beetles feed on nectar or feed on pollen or gnaw on floral tissue, other insects suck nectar. Some wasps chew holes at the base of the flowers [prf] to suck nectar [sn@prf], or they take advantage of such holes [sn@prf]. Observations are from Robertson and Wilhelm & Rericha.)
