Default Bl**dy caterpillars...

It's not fair. My brassicas are supposed to have a chance to recover and
feed *us* over the winter, but last night I found a large caterpillar
actively feeding on the cavolo nero. I didn't stop to identify it, but I
think it was one of the usual whites. I can check if anyone's
interested; I suppose I should go and look for more of them. I also
wondered idly whether feeding over the winter would affect pupation,
etc.

I too have found the odd one, bright green, tucked inside winter cabbages
but usually find the spring cauliflowers (Walcheren Winter Armardo April)
free from any damage with nice clean, meat free, curds in April. :-)

Hi,

I have as well, saw a small bright green caterpillar being bashed by a Wren
the other day in my garden when we had that cold snap.

grrr. I prefer my Savoys without the lacework. I did grow caulis one
year, but they take a lot of space and I've only got about 4m^2.
More seriously, are caterpillars often active through the winter, or
have my brassicas simply been lucky in the past? I should have left the
mesh on longer :-(

Umm. I ring netted my cabbages as a protection against Pigeons but found
they were then destroyed by Cabbage White caterpillars. I wonder if
small birds that might predate the caterpillars are discouraged by the
netting?

Huh. There were midges performing a mating dance over my lawn,
yesterday.

Happy new year.

Probably the usual "winter crane flies/winter mosquitos"
Trichocera spec.

I've never seen anything other than wasps checking the brassicas for
caterpillars; I did wonder whether the whites have an unpleasant
flavour. For a week or three I even tried putting bird feeders near the
veg to encourage predation, but that simply resulted in my having to
wash everything even more thoroughly than usual :-(

I've rarely seen pigeons on the veg, although they're always on the
feeders, but a friend with small allotment a few hundred yards away
loses most of her kale to them, summer and winter. Vaguely amusing --
she had absolutely no idea what was doing the damage, assumed invisible
caterpillars plus kale-centred vandals from the local housing estate!

Having such a small growing area means it's easier to cover. I construct
a frame and use a fine plastic enviromesh that keeps out everything bar
whitefly -- although I have seen hordes[1] of whites trying to lay eggs
on leaves through the mesh. I spent some time trying to perfect a method
of killing the butterflies: I found it astonishingly difficult to take
them out of the air using a hose as the wings shed water extremely well.
The most effective weapon was a handsprayer full of water and detergent
(surfactant), followed by the heel of my shoe.

It's probably time to start prebaiting for slugs...

[1] There were an awful lot of them and I'm sure the largest was named
Genghis.

Maybe. They looked a bit big for midges. I was making assumptions from
the dance.

I'll try to catch one if they return.

Yes. Scale is a bit difficult. If that is Comfrey then I don't think
these insects were quite so big.

It is Sage /Salvia officinalis/

Sadly small birds at my allotment are rather scarce, though I have used no
netting, and pigeons haven't
yet been a problem.

I have to add that I was surprised just today to see a whole brood (word?)
on the crown of my sprouts. I squashed them! I have in the past had single
individuals skulking in the winter, but never a whole colony. I suppose it
was to do with the very warm autumn. They had done rather little damage,
presumably because the cold slowed their metabolism.
