My Willow tree is swarming with wasps. I can't really see why they're
there, and what they're doing. The willow is covered in black aphids but
the wasps don't seem interested in them. The wasps just land on the
leaves, walk about a bit, then fly off. What's so attractive about willow
for wasps?


Aphids exude a sweet, sticky substance called honeydew - I expect the
wasps are attracted to it in the same way as they're attracted to the
traditional wasp trap...jam and water in a jar.

A decent spot of rain should go some way to resolving the problem,
such as it is.
