Dozens of these butterflies were flying above and in between the grass on the edge of town last month – perhaps these were the vanguard of the enormous migrations that had many South Africans agog at their numbers earlier in the year. Apparently these butterflies need to frequently replenish themselves with nectar to avoid dehydration and are particularly attracted to grass nectar – which would explain the numbers of them that settled briefly on the long grass.
Their annual north-easterly migration usually occurs during mid-summer, although the actual timing may depend on factors such as drought and rain. During this time they provide food for other insects and birds.
