Nursery web spider
A spider I’ve seen many times in many kinds of locations – on the ground, once on a lily pad, in a shrub – but this is the first time I’ve seen this spider in a flower:
There’s a bit of lunch visible above the petal, a mosquito I think. Crab spiders are what I usually see on flowers, often on the underside of the petals. There were other discoveries in this sunflower patch, small milkweed beetles, and colony of red aphids.
