It’s like we live in a hyperspace bypass for thousands of Painted Lady butterflies, migrating from Mexico to Oregon.

“The butterflies do not stop to feed or mate until they have burned up their reserves, carried over from the caterpillar stage. They fly in a straight line from southeast to northwest, like “bats out of Hell,” and go over obstacles rather than trying to go around them, according to Davis researchers.

In 2005, the population was so dense that their numbers impeded traffic in desert regions, researchers said.” (source) with “reports of ‘billions’ of butterflies around Trona, near Death Valley, and in the San Fernando Valley.” (source ‘05)

  1. They are beautiful! I did not know about them and their journey. I only know about the Monarchs that come to Québec from Mexico.

  2. Love the close ups!

    Amazed they fly that far with no energy input!

  3. Crap. Factoid fail. I was looking for the start and end weight of a Painted Lady to estimate their MPG’s. Couldn’t find it, but I’d love to know the number if anyone else happens to know it.

  4. Thousands of lil messengers… just one message, tho.

  5. There’s a big migration going on right now. Quite impressive!


    Found in a search. (?)

  6. The photo and explanation are very interesting, but what I like best it’s
    the title 😀

    These winged messenger "packets" might be lithe, but the message encoded in the nucleus and mitochondrial DNAs is substantial, and probably exceeds several hundred Megabytes.

    To ensure reliable transmission, it seems that packet flooding and source-routing or autonomous routing techniques are used.

    A sequencing of the Californian flight route encoded in the DNA would probably yield something like this:

    CA VFR routing: Trans level FL3 orthometric. Squawk 7600 at all times. No relevant TFRs. MEXICALI: From MXL VOR to JLI VOR: Via MXL R-284 and JLI R-102. Thence JULIAN: From JLI VOR to PDZ VOR: Via JLI R-303 and PDZ R-122. Thence PARADISE: Via PDZ R-292 to KIMMO. From over KIMMO to EHF VOR: Via EHF R-49. Thence SHAFTER: From EHF VOR to PXN VOR: Via EHF R-299 and PXN R-117. Thence PANOCHE: Via PXN R-274 to WAGES. Cross Wages Int at FL2. Turn RIGHT and descend to intercept and follow OSI R-101 at or below FL1. Report quarter-mile to final. Expect vector to final approach course for landing net WHITE.

  8. burst out laughing too… priceless. nhr is the winged whisperer…

    Gi^2: yes. Always follow the female moth

  9. exactly.

    (eventhough nhr’s concept is not bad at all 😉

  10. I’ll be looking for them here in Oregon!

  11. beautiful creature, thanks for showing

  12. The painted ladies arrived in Northwest Oregon early this week. Here is one of them.

  13. very cool! I wonder if I saw yours en route. =)
