Curious...
So, it appears that these are specimens you never sent me, and that you haven't posted photos related to the one you did send me reared from the same host (stem borer, collected 8/20/17 at Meadow Farm--new species). Is that correct?

Correct re: stem borer
but I do have a record of sending you 5 specimens of the flower head borer (see email I just sent you).

Possibly M. minimoides
based on the following excerpt from Spencer and Steyskal's (1986) description of that species:

"Host/Early Stages. Many genera of Asteraceae, confirmed on Aster simmondsii, Borrichia frutescens, Helenium nudiflorum, Heliopsis helianthoides, Melanthera deltoidea, Rudbeckia laciniata, and
Verbesina virginica. Larva feeding and pupating in seed head; puparium whitish yellow, posterior spiracles (fig. 127) on widely separated conical projections, each with ring of 9 bulbs around central horn.
Distribution. Florida, Ohio; new records: Arkansas, Maryland; Venezuela." (p.32; emphasis added)
