The Genus Drepanaphis Del Guercio east of the Rocky Mountains. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006). Any errors in information are ours alone, and we would be very grateful for any corrections. We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. We have used the keys and species accounts of Smith (1941) & Smith & Dillery (1968), together with information from Roger Blackman & Victor Eastop in Aphids on Worlds Plants. We are also very grateful to Natalie Hernandez of Bugguide for discussions re identification of Drepanaphis species. We are very grateful to Vitaly Charny and Larry Clarfeld for putting their images of live Drepanaphis carolinensis under a creative commons licence. Of those aphid species, Baker (2015) lists 3 as occurring in Britain (Show British list). Blackman & Eastop list 10 species of aphid as feeding on red maple ( Acer rubrum) worldwide, and provide formal identification keys (Show World list).Of those aphid species, Baker (2015) lists 15 as occurring in Britain (Show British list). Blackman & Eastop list 16 species of aphid as feeding on sugar maple ( Acer saccharum) worldwide, and provide formal identification keys (Show World list).It has been collected from New Brunswick, Canada, to Georgia, west to Iowa and Kansas, USA.ĭrepanaphis carolinensis has been recorded on 4 species of maple ( Acer Acer barbatum, Acer nigrum, Acer rubrum, Acer saccharum). This is a common species in North America east of Rocky Mountains. The body length of adult Drepanaphis carolinensis is 1.6-2.2 mm.ĭrepanaphis carolinensis is monoecious holocyclic on maple ( Acer), mainly Acer saccharum, but sometimes on a few other Acer species. Drepanaphis acerifoliae, which has blunt hairs on the dorsal tubercles). Hairs on dorsal tubercles are pointed (cf. Drepanaphis acerifoliae which has tubercles on I & III approx. There are 4 pairs of well-developed uniformly dark brown spinal tubercles, those on tergite III being twice as long as the others, those on I, II and IV being approximately equal (cf. The abdomen has pale marginal sclerites on tergites I & II, and dark marginal sclerites on III-V. Drepanaphis acerifoliae & Drepanaphis keshenae, which have wing veins fuscous bordered).įirst image above copyright Vitaly Charny, second image copyright Larry Clarfeld,īoth under a Creative Commons 3.0 License. On the wings, the base of radius and pterostigma are dark bordered (except a central clear spot), and there are slight smudges at the distal ends of the veins, but otherwise the wings are clear (cf. The front femora and the bases of the tibiae are dark. Drepanaphis knowltoni, which has the terminal process more than 9 times the base). The terminal process is about 5.5 times the base of antennal segment VI (cf. Antennal segment III bears 7-16 secondary rhinaria. Antennal segments I and II, the distal ends of III, IV, V, and the base of VI are dark, the remainder are pale. The head and pronotum each have 5 longitudinal white wax stripes, and the abdomen has many white wax dots, most pronounced at the base and tip of the abdomen. Drepanaphis sabrinae, which is orange rather than brown). These adult alatae have the head and thorax reddish brown, and the abdomen fuscous brown with a pale tip (cf. All adult viviparae of Drepanaphis carolinensis are winged.
