Monday Night Mystery: A Silken Identity

The Monday Mystery returns with a selection of fine arthropod silks:



Each shows a silk made by a different species; some are spider silk, others are from various insects. Your mission, should you choose to accept it, is to list the pictures above that show spider silk.

I will award 10 points to the first person to provide the correct answers with no errors. I will not award partial credit, and I will not allow multiple entries. Instead, take your time and get it right.

The cumulative points winner for the month of December will win their choice of:

1) A guest post here on Myrmecos
2) Any 8×10 print from my insect photography galleries
3) A myrmecos t-shirt

Good luck!

  1. I’m going to go with A, D, and G (though I’m less confident with G – I’m thinking it’s maybe a crop from the margin of a jumpers egg sac or something…). I’d be curious to know what all of these are!

  2. ABCDJ

    And because I’m laid up and will use any excuse to communicate with the outside world:

    A and D I can’t imagine being anything but spider webs (so I’m probably wrong!)

    B… regularly spaced, looks like sticky droplets on the web, but might be dew… I’m going with spider.

    D looks like a purseweb type spider to me. I’ve seen webs like that binding leaves together with spiders hiding inside, too.

    E is clearly a butterfly cocoon support strand.

    F looks like ant cocoons to me. There’s even an ant in the picture.

    G looks like spider-mites to me. Could easily be wrong here.

    H is tent caterpillars. Now, when I was growing up, I was told that tent caterpillars stole their silk from spiders, since everyone knows only spiders make silk, but that’s just one of many old-wives tales I was presented with in my youth.

    I looks like those glowworms that hang from the roof of caves in South America. I remember seeing them in one of Attenborough’s programs, but don’t remember what they were called.

    J looks the webbing I’ve seen some spiders use protecting their eggs. I could easily be wrong here, though. Who am I kidding, I could easily be wrong everywhere. : – )
