How come tandem house flies can still fly? - Aerodynamics Question

    I’ve noticed that we have scientists, aeronautic engineers, biologists in our membership. So I thought I would ask a question that has plagued me since I was a kid when I first noticed two flies locked together - presumably caught in the act of mating.

    As far as I can tell, one set of wings are disabled… and so flight parameters have been compromised:

    • Twice the payload

    • Twice the drag

    • Halved and severely obstructed lift

    • Response lag

    • Diminished visibility


    And yet seemingly, when shoo’d off - the pair can take off and get away just as easy as if it was one fly. How is this possible? Seriously curious...



    Keep it clean folks. We want real answers, not innuendos!
    (I hope I don’t regret posting this…) :rolleyes:

    This would be a good week to quit smoking weed (kidding).
    Do we KNOW that one set of wings are disabled?
    Flight is one thing, but getting where either of them actually intends to go may be another.
    I usually find that a fly swatter makes it a moot point.

    I've seen this phenomena, and have noticed the front fly's rear set of wings is sometimes compromised by the legs of the one on the back.

    And I have noticed that coupled flies are often less reactive and slower.

    Found this out during summers cooking in unairconditioned kitchens. One such had a poorly fitting warped screen door to the trash dumpster within feet of the kitchen. Really hard to keep flies out. Flypaper would be filled within hours of putting up.

    The wire strung through wooden clothespins to hold tickets was often covered solid with flies- red headed deer, blue bottle, black, and common house flies. Literally every time the health inspector was there she'd write a violation for excessive flies in kitchen, even though she understood that it was nearly impossible to keep them out.

    Why can a 5 foot tall human jump only 8 inches high when an 8 inch tall cat can jump 5 feet high?

    When your entire life lasts less than a month you figure stuff out fast...

    Only the ones that survived your swatting figured it out.

    The answer is actually simple. The lift generated by the two pair of wings is sufficient to overcome the pull of gravity. Regarding drag, the flies are not flying at 60 miles per hour, 88 ft/sec. They're not even flying at 1 ft/sec. Drag is insignificant. Balance, maneuverability, and air speed are affected. It's easier to swat them when they're flying coupled because their balance is off, they can't turn as quickly, and their acceleration and airspeed are adversely affected. The wing angles for two pair of wings on two coupled flies will never be as efficient as they would be separated.

    Questions that have haunted us from childhood can be difficult to ever resolve.
    However I think they are more common than one would think.

    I was always perplexed because, How do I really know they have improved the taste of dog food?
    I see the sign, New and Improved Taste, who decided that this dog food is better tasting than the old kind.
    See what I mean? Perplexing

    Power to weight ratio....

    a fly's wings must be super efficient and cope with the extra weight of the second fly....

    Besides....no fly girl is going to mate with you if you don't take them for a spin around the neighbourhood and visit your fav take away food joint....:D

    Either love, or funk.
    I can never figure it out.

    Why do we assume that most mating flies can fly? For every pair that flaunts it, there may be hundreds that are more discreet.

    The ones that are flying are probably high.
