Cebysa leucotelus (Walker, 1854). Adventive.
Adults are found in March and April in cities; parks and gardens, where the microclimate is warmer and drier. The flightless, metallic-looking female is often observed on the ground. The male flies actively in the sunshine in search of the female.
The larva constructs a soft brown oval silken case ornamented with small fragments of lichen. It feeds on lichens on rocks, walls and tree-trunks, retreating into the case when disturbed. Over the hottest months the larva retreats to a cool place and apparently does not feed, pupating in late summer in the case.
