I don't think there is an attached Psychid case. I think the flower head has been folded over giving that impression. Compare your image with e.g. Sighting 4669180 and imagine the tip section folded down. On the other hand the brown thing on top of the flowerhead may well be a case caterpillar, in this sighting Sighting 4473636
dear CarbonAI being colour blind is all very P.C. but does not help when identifying these colour coded critters. Thallarcha partita generally has a yellow fore wing background colour above moth has white.
