Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae.
Fraxinus caroliniana, the pop ash, Florida ash, swamp ash, Carolina ash, or water ash, is a species of ash tree native from Cuba through the subtropical southeastern United States from southern Virginia to Texas. It was originally described by the botanist Philip Miller. It is a small tree about 40 ft. Leaves are compound, opposite, 7–12 in long, leaflets 5–7 in, ovate to oblong, coarsely serrate or entire, 3–6 in long, 2–3 in wide. Fruit is frequently 3-winged (samara) with flat seed portion; seed sometimes a bright violet color. It is the smallest of eastern North American ash species, wood light, soft, weak, 22 lbs./cu.ft. Typical to coastal swamps and subtropical lowlands. Like other species in the section Melioides, Fraxinus caroliniana is dioecious, with male and female flowers produced on separate individuals.
