Default Solomons Seal sawfly


Admiring the grey caterpillars of the Solomon's Seal Sawfly demoloshing
our plants (happens 'most every year - not last year tho'), I wondered
why they seem to have no natural predator.

Anyone know?

Ah. So that's what they are. I have a flock demolishing the pond flags.
My solution has been to clog the leaves sharply with a broom handle and
hope the buggers can't swim:-)

A pair of Moorhens are rearing 6 chicks and showed no interest. Lots of
Blackbirds feeding on the Wild Cherries close by. Perhaps they taste
unpleasant?

My first thought was perhaps, like the caterpillars of Cinnabar Moth or
Monarch Butterfuly, they absorb toxins from the food plant. But on
googling I find that Polygonatum is of low toxicity, so perhaps that
isn't the case.

Interesting. It won't be the SSS as these are species specific. But
there are a wide range of sawflies.

Yeah, well, I haven't been able to carry out a tasting session, hence
the question! ;-)

These have grey backs and cream tummies and are currently 25mm long. Is
there a rogues gallery available on line? My Collins book only gives the
Birch Sawfly.

I did a Google search on Solomon's Seal & Pests.
