Seed sowing continues in earnest. In the greenhouse, whilst sowing some seeds I spotted what looked like a small red spider.

Initial research suggested that it was a red spider mite, threatening to infest the greenhouse and ruin my plants. I hadn’t killed it of course so was that the case?

Yet close up images didn’t quite match up and a bit more digging around on the web found this
Red Velvet Mites
So it isn’t a foe, it’s a friend! http://www.cirrusimage.com/Arachnid_velvet_mite.htm
from this site it appears that they serve as an important link in the ecosystem web.
Next up on my greenhouse guest list was a millipede

I thought a millipede was a millipede but on research it seems that there is a whole family of differing types

Final conclusion: The sieved soil from the base of the cleared compost heap is teeming with useful wildlife 🙂
