Gruesome Tactics of an Ant-Snatching Assassin Bug

26 July 2013

This post highlights the gruesome, yet ingenious tactics of the Ant-Snatching Assassin Bug (In Singapore, Acanthaspis sp. and Inara sp.) which I shot again on Friday night. This assassin bug sticks the corpses of it’s devoured prey (ants!) onto it’s back for camouflage and to hide it’s scent from other ants. On top of being an obvious “meat shield”, this also allows the assassin bug to infiltrate ant colonies while posing as one of their own. I have yet to photograph this bug attaching a corpse to it’s back, so it’s going to be high on my wish list!

There are at least 2 species of these assassin bug nymphs: Inara flavopicta and Acanthaspis. The nymphs are difficult to differentiate, but Inara tends to have a cleaner stack of corpses, while Acanthaspis may include some debris on its back.

    Like a scene straight out from the recent Hannibal TV series (Episode 9: TROU NORMAND), this Ant-Snatching Assassin Bug (Inara sp.) accumulates a gigantic stack of corpses on it’s back. It’s a wonder how it managed to maintain balance!

    This Ant-Snatching Assassin Bug could walk about steadily despite the additional load.

    Another serial killer which I shot some time ago, had a slightly lower kill rate.

    Even the tiny, younger Ant-Snatching Assassin Bug had a stack of it’s own!

    View from above shows that almost the entire body of the Ant-Snatching Assassin Bug had been covered by ant carcasses!

    Despite finding these quite frequently, I couldn’t pass up shooting them each time.

  12. Shooting this assassin bug took just about 10 minutes, so here are more finds from the night!!

    Wider view to show the web – yes it is almost always hanging upside down.

    Issid Planthopper , ridiculously cute seed-like bug! Alex Wild jokingly called it Adorabilidae when I posted pictures of it on Facebook recently.

    Did I mention that it is that adorable?

  31. Katydid (Tettigoniidae)

    Interesting looking Katydid but it was too big to fit into my camera setup, hence the cropped legs.

  32. Caged Pupa - DSC_0661
  33. Caged Pupa

    Melvyn found this caged chrysalis. The caterpillar was probably a spiky one, and had used it’s spikes to build this protective cage while it is in this vulnerable and critical stage of it’s life.

    View from the side, such a beautiful chrysalis!

    The outer membrane was already transparent and we could see the antennae of the moth.

    There were a number of these Orb Web Spiders which rested on dead leaves dangling on their webs.

    One of the benefits of shooting at night, are the congregating Tiger Beetles

  46. Tiger Beetles (Cicindelinae) - DSC_0791
  47. Tiger Beetles (Cicindelinae)

    I would usually give these Tiger Beetles a miss, but this pair was sleeping side by side and it looked like a good photo-op!

    Like brothers!
