The larvae phase of Processionary Moths that appear in caterpillar type form are currently active and are best seen when crossing roads.
Processionary Moths are from the family Thaumetopoeidae, sub family Notodontidae and a genera occurring in our region is Anaphe. Six species are recorded.
Processions take place when migrations occur between feeding stations. In the Lowveld tree species such as Dombeya (wild pear), Sideroxylon (milkwood) and Diplorhynchus (horn-pod) are the sought after host plants.
The most striking activity during the reporting period has been a sudden influx of thousands upon thousands of Red-billed queleas (Quelea quelea). To describe their numbers and activities in words is almost impossible. It is a show of natural wonder in the skies that only eye witnesses might truly appreciate.
