oa Journal of the Entomological Society of Southern Africa - Preliminary observations on Colias electo (L.) (Lepidopt.: Pieridae) in Southern Rhodesia
The data on which this paper is based were collected in and around Salisbury, Southern Rhodesia, during the latter part of 1957 and early 1958 whilst carrying out a preliminary study of Colias electo (L.) as part of an investigation into the insects associated with lucerne. In addition to laboratory and insectary study of the life history of the species, observations were made in a small field of recently-planted lucerne about 18 miles from Salisbury. Descriptions of the stages of C. electo have been given by van Son (1949), Jarvis (1953) and Pinhey (1949) and so are not included in the present paper.
