Att vara humla – Being a bumblebee

Det finns ca 250 arter av humlor i världen. En vanlig myt om humlor är att de enligt fysiska lagar inte borde kunna flyga, och att det är en gåta att de flyger ändå.  I verkligheten karakteriseras humlans flykt av en oscillerande vinge, som mer påminner om ett helikopterblad, än en flygplansvinge. Utöver det skapar humlevingens form och rörelsemönster en luftvirvel precis ovanför vingen och den gör också att humlan får ökad lyftkraft.

Idag har jag tillbringat säkert en halvtimme med att titta på en mängd humlor som flitigt jobbade och samlade pollen i azaleor och rhododendron hos en arbetskamrat. Snabba är de, så de få foton som humlorna verkligen fastnade på är med i detta lilla galleri. I regel visade bilden bara en blomma och möjligen några humleben redan i luften när jag klickat…

There are over 250 known species of bumblebees, existing primarily in the Northern hemisphere, but they can also be found in South America.  Bumblebees have been introduced to New Zealand and the Australian state of Tasmania.

According to 20th century folklore, the laws of aerodynamics prove that the bumblebee should be incapable of flight, as it does not have the capacity (in terms of wing size or beats per second) to achieve flight with the degree of wing loading necessary. It seems their wings work more like a helicopter. They also start a swirl in the air above the bee which makes it easier for the animal to take off.

So, they do fly…and they are fast! I spent maybe half an hour today at a friend’s house, trying to catch more than his beautiful azaleas …but, mostly I got just the flower and som bumblebee legs lifting when my camera had finished clicking…

  1. Beautiful!! I really enjoy trying to capture the bumblebees when they are flower hopping, only once was I successful!! You captured so many perfectly composed shots…I really love them all!!

  2. The lovely fuzzy bumble bee, I love them so much. The way they bump enthusiastically around the inside of big flowers, and emerge pollen dusted, and flying a bit drunk on nectar…..they stagger on to the next flower 🙂

  3. Humlor ser så harmlösa och gosiga ut. Fast dom är inte sköna att trampa på.. Råkade prova det en gång….
    Man får passa sig när man går barfota i gräset 😉

    Härliga bilder…..älskar den rosa färgen!

  4. Lovely photos. Bumblebees, as they bumble about, always look as though they will be easy to photograph but it is really hard to catch them at exactly the right moment.

  5. I love bees and humblebees … and I can stand and watch them for 30 min without problems. I didn’t know that there was some many species of humblebees. You have been watching them too … I can see from your lovely gallery. I very seldom manage to get them in shot, they are too quick for me.

  6. Great work! You should be so proud of such a Gallery. The pinks are so appealing as are the Bees which you captured perfectly!
