and Nymphalidae (emperors) the two front legs are very short, have no claws
and are useless for walking. I thought Papillionidae (swallowtails) were
the same but they're not, they have 6 good legs.
It gets wierder. In Riodinidae, the males have 4 walking legs but the
females have 6.
Lycaenidae (blues) and Hesperidae (skippers) all have 6 legs.
What on earth can one learn from that?
Anyway, Alan asked what "bugs" are quadrupeds. I said mantises, monarchs
and swallowtails. I was wrong about swallowtails. I was taught all this
stuff decades ago so forgive me if I'm a bit rusty. I even spent one summer
as a student doing fieldwork in the west of Virginia catching swallowtails
and monarchs so I certainly _ought_ to have remembered the details.
I still can't think of any other arthropods with just 4 walking legs. I
think some crustacean larvae have only 4 legs but they don't use them for
