Lemurs use toxic millipedes as insecticides, get high as a byproduct

March 9, 2017 • 3:15 pm

From BBC One program, “Spy in the Wild”, we learn that lemurs not only rub millipedes on their skin to deter insects (mostly mosquitoes who are repelled by the millipedes’ benzoquinones), but also seem to get high from chemicals in the ‘pedes. This isn’t just speculation: there’s research to support at least the insecticide part (see here). I’m not sure the lemurs really enjoy this “intoxication”: it may just be a psychological state that is a necessary byproduct of biting the millipedes.

    1. It’s at moments like this that Jerry’s gastrognome reputation comes back to, errrrr, bite him?

    1. Somebody call Andrew Zimmern…

      Actually the Yooman Race has a long and honourable history of snacking on dangerously poisonous substances in order to get high, or zonked, or paralytic…

      It’s kinda comforting to learn that we’re not alone in this.

    2. You holdin’ — or asking for a friend? 🙂

      Personally, I draw the line at toad-licking.

      1. There are millipedes in Alaska. with benzoquinones

        and very definitely there are mosquitos

        I’ll probably skip ingesting and try them as roll-ons.

  1. My guess would be ancient lemurs (or forebear species) discovered the “high” and enjoyed its effects. The insect repellent effect was a side-benefit. Later, natural selection favored the rubbing through their fur behavior upon getting high.

  2. It’s a gateway bug!

    [I stole that from “Will N” in the YouTube comments section]

  3. Jeez, who woulda thunk it. Zonked-out stoned hippie lemurs.

    I found that millipedes were poisonous when I let a few small ones crawl over my hand (this was in Rarotonga) and then developed an itchy rash.

    1. But I’d be quite surprised if mosquitos could even bite lemurs. Aren’t they too furry?

      1. Ears, eyelids, lips, nose, anus .. you know, all the places mosquitoes bite me.

  4. I wonder if such venom has useful medicinal value for us naked apes. The human trials might be entertaining.

  5. Well, that would explain those eyes lemurs display…
    Jokes aside, I’d favour S.K.Graham’s explanation.

  6. New world monkeys, too: “Members of a wild group of wedge-capped capuchin monkeys (Cebus olivaceus) intentionally anoint themselves with millipedes (Orthoporus dorsovittatus). Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects.” Valderrama et al, J. Chem. Ecol.(2000)

    No nomming, just topical

  7. Oh, if only I could be a lemur, getting high whenever I want…

    Instead, I have to go through getting the stuff, setting it up, finding a nice place to do it…

    Actually, I prefer my way. I would bet lemurs don’t get to listen to Yes or Rush or Pink Floyd when they get high!

  8. “Warning: do not take the brown acid millipedes. The brown millipedes are bad, man.”

  9. Can you also use hoofed mammals in the same way?

    I’ve always wanted to rub myself with ungulates.
