Nice pic and video!
Very beautiful and very instructive. Thank you, Jasmine! These are two males defending temporary territories. Note the bristles on ther lower insides of the first two pairs of legs. Only the males have these bristles and they seem to be of significance when they touch each other. - For more info you may wish to go to facebook.com/darwinfoundation.
