A few thoughts to add to this - 1) Males emerge earlier than females, but I'm not sure what the "delta" between emergence times is for the Vapourer, but that would reduce in-breeding, possibly to the extent that there is none, 2) If there is overlap in emergence times then the second and subsequent matings could also be siblings! ... and 3) The females will also benefit from the "nuptial gift" (various nutrients) that are passed from male to female, along with the necessary I guess it's all down to probabilities ... someone should look into this!
