The little caterpillar/larva munches a corridor in the stem of Brown Knapweed and creates an exit hole for itself to emerge through once it has finished development to imago (planning ahead!), then retracts into the flower bud, feeds some more and pupates - strangely somehow always "backwards" (bum pointing to the exit hole). I opened this flower bud (from the stem) to have a better look...<br />

Half of stem peeled away to see corridor with frass and the exit hole from the inside:<br />

Exit hole under different flower bud. The larva seems to have a clear preference to chew out the exit hole such that it is hidden behind a leaflet:<br />
