Oh lordy. Thanks for the info. Are these likely to have been hiding on
the plant for a while? We've had a lot of cut flowers in the house
recently - maybe they hitchced a ride?

As for the black spots - they seem to be mostly on the top side of the
leaves, but also on the underside. There aren't too many on the leaves
and they're very tiny. A lot of the leaves have dropped off, with stems
attached. It's not looking good, is it?

Leaves affected by spider mites usually turn gray/silver although what you
are seeing may be a result of the mites.

They have been there a while if you are seeing webs, you may have to spray a
miticide several times. Be sure to get the underside of the leaves as well
as the surface of the soil.
