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,
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?
