    I honestly never thought I would say this…

    Unicorn chaser, please. Quickly. -shudder-

    So the beetle is basically a heavily armored troop carrier, a vast star destroyer loaded with tie fighters, a Lovecraftian juggernaut crawling with flesh-eating minions. Wicked.

    This is quite a good metaphor for the current political situation in the UK. With the current coalition government, the Conservatives are the carrion beetle, and the Lib Dems are the mites. When the “beetle” is confronted with an election, the “Lib Dems” get rid of the Labour competition, allowing the Tories to win.

    This is truly great.

    I wonder what the exact trait is that the beetle evolved in order to get her cape of fighter-mites? This symbiotic relationship must be two-ways, or the mites would never bother latching on. Maybe the beetle excretes some substance that is particularly delicious to mites?

      Isn’t the free, unlimited bus ticket to food the main benefit to the mites? Doesn’t that make it symbiotic? Or does there need to be some other direct benefit for it to count as symbiotic?

      Pretty cool, but imagine waking up with a bunch of those in your bed?

      Not that it’s very likely considering not everyone who reads boinboing has carrion in their bed on a regular basis (Prostitutes can be fragile).

      Actually, many mite species hitch rides on beetles (and other invertebrates) just to get around (try walking long distances on those short legs). This is called phoresy. It’s highly probable that these mites started that way and quickly adapted to exploit the added bonus of an excellent food source.

    Seriously, to abuse the possessive apostrophe, not once, but TWICE!
    And from a professional writer, too (not that I don’t make my own egregious typos, but still…)

    Reminds me of the Amaryllis Azure, which lays its eggs on mistletoe which grows on a tree that has been colonised by little black ants of the genus Papyrius.

    When the eggs hatch, the ants provide shelter for the caterpillars in their nest at the base of the tree or under the bark. The caterpillars are shepherded by the ants to a clump of mistletoe at nightfall to feed and then led back to their shelter at dawn.
