Notes:
|
First recorded at Harare airport and northwards on the Airport Rd towards Harare on 17 May 1990. A search for the species in the southernmost suburbs of Harare two days later revealed a number of further ocurrences of this species.
Subsequently, Laegaard discovered the species at Dunhiku School in 1991 and it has since been seen at the adjacent Cleveland Dam.
Further records exist from the Mukuvisi Woodlands and from the Tobacco Research Station, Kutsaga, which is very close to the airport.
In my opinion, the species is an introduction, possibly via the airport, and is now locally abundant in the S and SE parts of Harare.Interestingly, it is an alien from another part of Africa. |
