micro moth with unusual pupa casing - Dahlica triquetrella
Buffalo County, Wisconsin, USA
June 13, 2009
Size: very small - 5 or 6mm
I found this pupa attached to a birch trunk. It seems to be made of bits of sand and debris. I kept it, and found a small moth in the jar on 6/24/09. There must have been two pupae attached to the same piece of birch bark, because the pupa seems to be a different creature than the moth.

Case
Are you certain that the moth came from this case? It looks very much like the case of Dahlica triquetrella (Psychidae). I can't find any information about the larva of Ortholepis pasadamia, but according to this website, the larva of the British O. betulae lives and feeds between leaves spun together with silk--a more typical habit for a pyralid.

moth casing
You may be right. I collected the case (on a piece of birch bark), and the moth hatched in the same jar, but it may be that they're not related. Maybe the moth cocoon was attached to a different part of the birch bark, and it was small enough that I didn't notice it. Shall I unlink or remove the photo?

The best thing would probably be
to unlink this photo, move it to Dahlica, and add thumbnails to cross-reference the images.

moving and linking images
Does the way I've linked them make sense now? (It was good to learn how to do this - thanks!)

Perfect!
That's exactly what I meant.
