Food Plant: Eupatorium cannabinum (Hemp Agrimony)

Mine: unknown at present (but puparia found November-May).

Notes: Puparia found low down in the stems (from 40-120mm from the base). The puparia can be separated from M.eupatorii (found on the same host) due to the presence of a strong central horn on each of the posterior spiracles (as shown), whereas M.eupatorii has posterior spiracles which are separated and with a very short central horn. Found at eleven sites across East Anglia (Suffolk, Norfolk and Cambridgeshire) but may be more widespread.
