Monday Night Mystery

What’s this?

Five points for picking the family, five points for the genus.  And infinity points for figuring out what the those balloon-like structures are for. I have no idea.

    I can’t even tell if it is coming or going …

    Striking photograph regardless.

    Ooh, and do i get extra points for saying that it’s being attended by Azteca velox? I’m really excited right now.

    “In these obligate symbioses the

    exaggerated balloon setae surrounding the head of

    Theope caterpillars (figure 1) appear important in med-

    iating associations with dolichoderine ants by providing

    semiochemical stimuli to ant symbionts (DeVries 1997).”

    From “Ancient butterfly-ant symbiosis: direct evidence from Dominican amber” (DeVries and Poinar 1997).

    Gosh, is this the DeVries who has some show on Animal Planet?

    I found something that refutes that and says they’re “used to store and disperse a noxious chemical when the caterpillar or pupa is grabbed by a predator, rather than to facilitate a symbiotic relationship with ants, as previously suggested.” I can’t access it, but you might.

    Well, time to get to my homework, then!
