suggestions: the first sketch at the left put below: LATERAL VIEW of the leg.
The middle: SEEN AS ABOVE, as we cut the leg transversally, being the ventral.. the underside of the leg. (exempli gratia, ventral seta/bristle: the insertion of the ventral bristle is located in the underside of the leg (considering the frontal view of the last photo) . So we almost (see below the text) cannot see in this last photo the insertion of ventral setae with the most proximal legs (foreground) to us, the distal ones sometimes show them but not easy to see! However, we can see the point of insertion of ventral bristles IF the leg is twisted like it happens in the hind tibia where we can see av with its insertion point - I'm considering the fly as always being transverse with us.)
The right sketch (above all of them) I would suggest to put below the legend SEEN AS ABOVE , but this time, as we had our fly with the biggest length transversally to us. This view is perfectly showed in the last photo.
(caution: the hind tibia is gently twisted in this view. That's why we see many ad)
