I found these curl grubs yesterday sitting on the top of one of my pots. There were three of them just sitting on the top of all the leaf litter. There isn't anything in this particular pot, but what worries me is that I have a dwarf lemon tree in a large pot not too far away, and these grubs feed on roots.
I have been doing some research this morning & found out that these grubs are the larvae of beetles, which I find very interesting. As these ones were about 4cm long, I would like to see the beetle that they tun into. About an hour later they were no where to be seen. Possibly buried back into the soil in the pot, or maybe lunch for my favourite magpies.
