Superfamily Gerroidea

Family Veliidae (Smaller Water Striders)

Other Common Names

Riffle Bugs, Broad-Shouldered Water Striders; Ripple Bugs (genus Rhagovelia)

Explanation of Names

Veliidae Amyot & Serville 1843

Numbers

the largest gerromorphan family, with almost 1000 spp. in ~60 genera worldwide(1); second largest in our area, with 34 spp. in 5 genera(2); 9 spp. in 2 genera in MI(3); 18 spp. in 5 genera in FL(4)

Size

1.5-6 mm(4) (exotic spp. up to 9 mm)(5)

Identification

pronotum broader than abdomen (as reflected in the common name); hind femur not longer than abdomen; pre-apical tarsal claws; usually wingless and dark-colored, sometimes with silvery markings

key to NA genera in(6)(4)(7)

NB: to tell adults from nymphs, look at meso-/metatarsi (one-segmented in nymphs, two-segmented in adults)

Range

worldwide; in our area, so. Canada and throughout the US(6)

Habitat

on water surface among vegetation in temporary or permanent ponds, lake margins, placid areas of streams (Microvelia and Velia species) or in rapids/riffles in streams (Rhagovelia species); some may be found on plants away from water(4), also saltwater habitats, mud flats(1)

Food

predaceous on other surface-dwelling arthropods, detecting prey via surface vibrations

Remarks

Pretarsal structure most diverse among Gerromorpha, the mesotarsal ventral arolium (turned into a 'swimming fan') being the most distinctive feature(8)
