A mature St Andrew’s Cross spider (Argiope keyserlingi) has set up her web between two maidenhair ferns on our back patio and I noticed yesterday morning that she had caught and wrapped a substantial meal, perhaps a fly or a small moth.
Looking more closely after lunch (my lunch, that is, not hers), I saw a much smaller spider hanging around in the edge of her web.

The macro lens with a close-up filter was able to show that it was a Dewdrop Spider, Argyrodes antipodianus, and even that it was a male (those “boxing gloves”, really enlarged palps, are the giveaway).
