User's notes

Found on footpath between grasslands, has a case that looks like it's made of grass and herbs. Likes to eat grass, two seed vetch and leaves of a desert pea (Swainsona tephrotricha?), occasionally also wood sorrel (oxalis) and clover flowers. Case is 1.5 cm long. Started moving about restlessly for at least two weeks (seemingly not eating), before parking itself with the case front opening down to soil. No movement after 25/11. Case length 2 cm at this point.

Not a moth?

Sorry, not yet a moth. This one is still a happily eating caterpillar. I hope to be able to post a sighting of the moth in future if we get to that point

OK,i ts certainly an insect larvae, I was just querying wheteer it was in fact a moth.

Oh, ok - I thought it is a case moth, looks like one I had last year with a different type of case. But I don't know for sure. What kind of picture would best help show if it's a moth caterpillar or a different insect?

Your photo is excellent. Good luck with rearing the catepillar to adulthood. We usually assume that radically different pupal cases mean different species. Likely Psychidae, but I ccannot say for sure,

Thanks, that's good to know - hope it will make it to adulthood
