Thank you for remembering my precious Orpheus!
Unfortunately, Orpheus hatched in the dead of winter when there were no Oecanthinae out yet, so there was never a lady for him. I've never met another varicornis who sings like Orpheus sang - his voice was so clear and loud and hauntingly beautiful.
Orpheus lived as a full adult for four months (!) and now I'm thinking that might be because he never mated. From what I can guess from the ones I raise, producing spermatophores and perhaps supplying metanotal fluid is quite expensive for males, as is egg production and laying for females.
I only have a very small handful of nymphs, and they are the grandnymphs of the ones I collected last spring as mostly third- and fourth-instar nymphs.
