In March when we still had a significant amount of green around our building, with lots of small orange flowers we had a lot of butterflies visiting including two types of Blues (the one pictured and a tiny species with a wingspan perhaps half an inch across). Also we had a good number of Cabbage Whites and Painted Ladies. In April, as the Eucalyptus trees flowered, we had massive numbers of Painted Ladies on base. I counted over 300 in a short walk to the gym and back. For a week or so they were everywhere, including getting in the buildings. I had the same experience with a sudden explosion of painted lady numbers at the same time as the Eucalyptus flowering. Recently I have been seeing some more blues and this butterfly (some type of Nymphalid) with dark wings and orange spots.
