Insects, bugs etc for ID please

[annew]

It's about time we had a thread for our invertebrate experts.
I noticed today that my lovely Larix kaempferi Nana had been half-defoliated by something. On closer inspection, these little monsters were revealed. Any ideas? Google is not terribly helpful so far.

where are blue tits when you need them!?

..perhaps larch sawfly caterpillars..

..... haven't they got dark heads?

Looks like a Winter Moth Operophtera brumata : http://ukmoths.org.uk/show.php?id=1205

They feed on many trees and shrubs and can become pests.

Defenitely some kind of sawfly.

I don't think I can add them to my sawfly collection, they don't look like the photos of larch sawfly. Winter moth looks right but my larvae aren't loopers.

Is it the two lined larch sawfly?

[annew]

They have 8 pairs of pro legs and are smaller than mine even full-grown. Says google.

Anne,

They only loop when you are not looking  .

Try to keep one to metamorphosize and you'll know what kind of bug it is.

With apologies to Aristotle, I'm not sure if I have any live ones left….

I am sure he wouldn't mind you saving the Larix

Anne:

What did you use to 'control' the pest?

A friend found this in her garden ( Ohio, USA) yesterday.
Neither of us have ever seen anything quite like it before.
Not a very good pic but only one she had.
Hoping someone can ID it.

Its a Red Headed Bush Cricket, Phyllopalpus pulchellus.
