The most striking and consistent feature of rare aphid species is that the period suitable for their development and reproduction is shorter than for the common species and, consequently, the potential yearly rate of increase of these rare species is lower. Thus, in addition to the abundance of host plants determining the abundance of aphids (Dixon & Kindlmann, 1990), their potential yearly population growth rates are also important. Contrary to current thinking, it is likely that many of the striking differences in life‐history traits of rare species are consequences, rather than causes, of rarity, and have evolved because they are rare.
