Dear Sylvain,

If those two species are different, then the diagonal purple lines on the mantle would suggest it is H. nigrostriata. In the other species the lines are said to be parallel. Your photo is another nice record of this species feeding. Although we have earlier records of it , and H. zephyra, feeding on this purple species of Dysidea, the more records we accumulate help to confirm its feeding preference.

Best wishes,
Bill Rudman
