New species of Louisiana Aphididae, and notes on Sanbornia juniperi. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006). Any errors in identification or information are ours alone, and we would be very grateful for any corrections. We fully acknowledge these authors and those listed in the reference sections as the source for the (summarized) taxonomic information we have presented. We have used the keys and species accounts of Boudreaux (1948) (as Macrosiphum verbesinae), supplemented with Hottes & Frison (1931) and Olive (1963) (both for Uroleucon rurale), together with information from Roger Blackman & Victor Eastop in Aphids on Worlds Plants. We thank the photographers named in the picture credits above for the various images shown. Of those aphid species, Baker (2015) does not list either of these as occurring in Britain (Show British list). Uroleucon rurale, the only other Uroleucon so far known to feed on Verbesina virginica, has a more northerly distribution being found in the eastern USA from South Carolina northwards.īlackman & Eastop list 2 species of aphid as feeding on frostweed ( Verbesina virginica) worldwide, and provide formal identification keys (Show World list). It is found in the southern USA states, including Louisiana, Florida, Arkansas & Texas. As far as is known, Uroleucon verbesinae is monoecious holocyclic. Uroleucon rurale, which feeds preferably on the stem). Boudreaux (1948) notes that it usually feeds under the leaves, moving to the stems when crowded on the leaves (cf. Uroleucon verbesinae appears to be restricted to feeding on frostweed ( Verbesina virginica) in the USA, but in Honduras it has been found on Verbesina myriocephala. Alatae have 25-36 secondary rhinaria scattered along all of antennal segment III.įirst image copyright Chuck Sexton, second image copyright C.A. Like the adult apterae, alatae of Uroleucon verbesinae (see second picture below) are either shining black or bright red. Immatures of the red form (see second picture above) are a slightly paler red than the adults, whilst immatures of the black form (see first picture below) are dark reddish brown.

Suspected Uroleucon rurale on Verbesina in Virginia, USA pictured in Bugguide are predominantly brown-green.įirst image copyright C.A. Note: Hottes & Frison (1931) describe Uroleucon rurale as having the head and mesothorax often brownish green and the abdomen very dark green, whereas Olive (1963) describes it as being grass-green. The siphunculi have reticulation on the distal 0.23-0.35 of length, comprising numerous small polygonal cells. Uroleucon ambrosiae, which has siphunculi less than 1.5 times as long as the cauda, which is pale). ![]() The siphunculi are long and black, more than 1.5 times the length of the cauda which is also black (cf. Dusky antesiphuncular sclerites are present, which on the live insect only show up on the red apterae. The dorsal hairs are without dark basal scleroites. ![]() The bases of the femora are pale yellow the rest of the femora and all the tibiae & tarsi are black. Uroleucon rurale, which has RIV+V 1.2-1.56 times the length of the second hind tarsal segment, and less than 4 times its basal width). The apical rostral segment (RIV+V) is very long and thin, 1.6-1.9 times as long as the second hind tarsal segment, and more than 4 times longer than its basal width (cf. Their antennae are slightly longer than the body and are uniformly black. Uroleucon rurale, which is greenish-brown - see note below). Adult apterae of Uroleucon verbesinae are either shiny black or bright shiny red (cf.
