I don't see them moving, now it's getting dark so I can't see well. I hate winter.
I don't even see any type of insects, the temperature at night should be around 0°C it's not a super ice cold but there is ice on streets and cars.
If spiders eats aphids I will be very happy!!! I really don't know, I'm not a real gardener, it's my first experience with any kind of plant!
