Figure 2From: Ecological correlates of sociality in Pemphigus aphids, with a partial phylogeny of the genusDemographic composition of destructively-sampled galls. (A) P. bursarius: breakdown of aphid instars (mean number per gall ± SE) over the duration of the galling season; (B) P. spyrothecae: breakdown of aphid morphs/instars (mean number per gall ± SE) at the Cement Works field site over the duration of the galling season. Note that the y-axes are on different scales.Back to article page
