This relatively recent accidental import from South Africa (originally on imported Pelargoniums, it is believed) is starting to colonise the south coast of France and is now quite common, and spreading its range northwards, either by natural expansion or courtesy of global warming. It is usually to be seen on Pelargoniums and can be seen in good numbers on hanging baskets in towns, although it is quite small and does not move very much, so can easily be missed.

The underside also adds to the camouflage, and the pattern makes photographs appear to be out of focus. The female is larger, but other than that the sexes are almost identical, as the male also has a completely brown upperside. All of these photographs are on cultivated Geraniums, to which they often seem glued, staying put for hours on end, on both the leaves and the flowers.

19544 F

a typical female upperside, on potted Geraniums on which it was egg-laying.

60
40270 F there aren't may opportunities to get an upperside shot as females on Geraniums are usually preoccupied with egg-laying and only rest with open wings occasionally, hence this shot of a rather worn individual. 60
40274   this female is actually in the act of egg-laying even though the end of the abdomen is obscured by the leaf. 60
40733   the same female as in 40724. 60
19539 F

the underside of 19544.
