FIGURE 1. Plots of mean scores on the first and second canonical variates for (a) 27 samples of apterae and (b) 13 samples of alatae, of the Aphis middletonii group from various sources in the BMNH collection (identified on slide labels as armoraciae, maidiradicis, menthaeradicis or middletonii). Samples comprised 4– 13 individuals collected on the same host at the same locality and on the same date (with the exception of two samples of trapped alatae). Seven linear parameters were measured on each specimen (lengths of siphunculus, third antennal segment, base of sixth antennal segment, processus terminalis, last segment of rostrum (combined third and fourth), hind tibia, second segment of hind tarsus). Data were analysed using the discriminant analysis package in Statistica (StatSoft Inc., Tulsa, USA), with the sample as the grouping variable.
