I don't know which of the Sawfly larvae this is, any ideas anyone? I found it hiding in a Brussel sprout from the garden.

I am not sure that it is a sawfly larva. Those tend to have a head that is oriented vertically, and this one has a sclerotized pronotum. Looks lepidopteran.

I am not sure of sawfly. I have been wrong before, will be again, but, my reasons. The face looks ' wrong' to me. Jaws too prognathious. Cannot see any prolegs(except anal), so loopers are out, and the skin colour and translucence are off. May it be a Pierid larva??

P.S., is that a mahogany table backdrop??

Larva of the grape leaf roller seems in the ballpark. Of course might not be exact species, but shows a general idea. Not a good picture but.. https://bugguide.net/node/view/1095838

Sorry, do not warm to that. Why would a grape roller be wandering? Much less on a Brascid. I see a similarity, but still would go with a Pierid. The head capsule is a close match. And they eat brussel sprouts (I did not untill I had them grilled. OMG, what I was missing).

Try to find fecal piles. They are distinctive with Pierids. Look in tight places at leaf bases.

Bill, I too was unsure about it being a Sawfly larva but decided on this due to believing it had more than 5 pairs of abdominal prolegs but perhaps I was wrong about that. We have had loads of Pieris brassicae and Pieris rapae. This is similar to P rapae but the others I have seen were more uniformly green, maybe this one is more mature than those I have seen. There is loads of frass of different types on the plants but heavy rain has disturbed it, I am not an expert of frass. I will look for another larvae. We do have a mahogany table but what you can see is a Lazy Susan of probably stained pine. Thanks for your expert help.

Thanks Mark, I was also unsure, perhaps it is Pieris rapae, I have seen these on the plants but they looked more uniformly pale green. I will look for another.

I could go along with it being a Pierid.
Thanks, job done.

Just because there is a consensus does not mean we are right.

Ha, ha. No, but I think it is very probable in this case and I can sleep now.
