Advertisement I found a bloodsucking conenose and was hoping to keep it alive for a bit. Has anybody ever tried keeping these? I'm not terribly keen on the idea of letting it bite me, even though I know Chagas is not really all that common in Arizona (where the bug is from) and is only transmitted when a bug carrying Trypanosoma cruzi defecates in the feeding wounds (or other open wound) - but however unlikely transmission might be, I'd really rather not take the chance. I would be willing to get blood for it by doing a finger prick - but can it take "loose" blood like that? What if the blood were on a bit of tissue or cotton or something? I would really appreciate any advice! Thanks!
