Anyone know why they chill out in big piles? 

This is one cluster among millions of ladybugs in the Forest of Nisene Marks.

  1. Oh!!! This is Woodstock for ladybugs!

  2. Yeah, a Love-In!

    Actually, it reminds me of aunts that created a huge tower (or building) that I vaguely recall seeing about on television.

  3. wow! I’ve never seen anything like that…if it weren’t ladybugs it would horrify me, but great capture!

  4. Maybe they’ve gone mad with pheromones/hormones. A flaw in their algorithm.

  5. some of them lost their spots 😛

  6. wow! No idea why they gather, I’ve always though ladybirds were solitary bugs 🙂

  7. Oh, no… they get psychotic in small groups…

  8. hahaha! you have an awesome collection of bug pictures.

  9. nice pic, the colors are very intense.

  10. Nice. I found a pile like this in Tilden Park a couple years ago, I should go look and see if they are back this year.

  11. It’s got a Seussian quality to it.

  12. Sir, those are no "ladies"!
    ‘-}

  13. A lady bug orgy? Hmmm…changes my whole perspective on the little fellas.

    Seen on your photo stream. (?)

  14. gregarious for over-wintering.

    one of those .."inexplicables"…like monarchs migrating to the same spot, across a continent.

  15. Thanks! The bug man is all knowing.

  16. If you ask me, They are Cloud computing =) sharing their "Bionarydots" for , as Todd suggested, simulating when is the best time to start hibernation =)

  17. In my neighborhood this is what they do for the winter, it beats being alone 🙂 If they are anything like bees they will shiver to keep warm.

  18. Cluster computation ? 😉

  19. eww I like ladybugs, but that’s too many….plus the multitude of the stink bugs around I’m none too happy

  20. ahhh, love bugs living the vida loca…

    ain’t we all after all?

  21. Wow! That must have been a hell of a party.

  25. Good one – not sure what the temperature was but they often hibernate in clusters.

  26. The species is Hippodamia convergens. As somme other ladybirds species (Harmonia axyridis, Hippodamia undecimnotata,…) this one forms aggregates to pass the winter. The reason is not well known. It could be to increase the aposematic signal (we are red = don’t eat us because we are toxic) or a dilution of the predation risk (if predator eat one individual, it will be disgusted by his terrible taste and will not eat other individuals of the aggregate).

  27. What a great photo ! I had a good laugh, with the notes and all ! ! ! !

  28. This photo and the others in the comments are too weird. I’m scared to look at any more of your photstream.

    … but also a little intrigued.

    … oh go on then I’ll be brave.

  29. Fascinating shot, and thanks, Gilles, for the scientific info.


    Seen in XploreMyPix! (Must have 20 faves; see rules) (?)
