I have some Cosmos grown from seed and now planted out.

Each night another one or two are being bitten off around 4-5" off the
ground and most of the leaves on the fallen bit left uneaten.

I am trying to puzzle out what is doing this.

I have a wildlife camera but pointed it at the wrong area last night (too
much down angle). I will try again tonight.

However I'm struggling with the logic of something snipping off the top of
the plant but then not eating it.

Any ideas?
Cheers

The obvious likely answer is 'slugs'. They might simply enjoy the juicy
stems more than the chewy leaves. A few slug pellets (and the resulting
corpses in the morning) should confirm this.

Or ants, and ant powder?
