Who munched the leaves of some Derwentia perfoliata plants, leaving smooth semi-circular holes at the edge? It was a native bee, a friendly pollinator. Solitary female Leafcutter Bees remove these discs from the leaves so they can use them for building their nests. The leaves are shaped into plugs that are filled with pollen and nectar for their offspring, then closed with a lid consisting of a neat circular piece of leaf.

So I look at the garden. I look at plants that love the heat, like Catmint. I look at plants that curl up to protect themselves but unfurl when the sun sets, like Lambs Ears. I look at plants that look uncomfortable but I know from years of experience won't be summer casualties, like orange Wallflowers. (The mauve ones are much more resilient for some reason).
And ... I look at, and for, insects, spiders and birds, and any signs of them.
The leaves of the Banksia Roses got infected with sooty mould. I didn't get round to removing the diseased leaves. Then I noticed some tiny black and yellow beetles on the leaves. Identified as Fungus-eating Ladybird beetles (Illeis galbula) - these cute critters eat fungus and mould! They are welcome. Leaving the sooty mould led to an increase in the biodiversity in the garden ecosystem.
