Odd question for you. I know that male Duke of Burgundy butterflies have only 4 legs, whilst the females have the normal 6, but what of the true fritillaries? The reason I ask is that I have recently been taking photos of various frits and on one or two shots, it appears that some have only 4 legs. I have noticed that on occasions, fritillaries will walk/stand on 4 legs, whilst keeping the front pair of legs, tucked away. These front legs appear shorter than the other legs.
Oddly, in some snaps it appears that BOTH members of a mating pair of frits have only 4 legs, but I'm sure this is not true. It must be the way at least one of the pair stands.
Also, if males of some butterflies emerge with only 4 legs, this situation must have been selected out by evolution over many generations as "beneficial" (there must be an advantage in having less legs). Any theories as to what the benefits may be? Is it easier for them to "get their legs over" so to speak, if there are only 2 rather than 3 on each side
