John, thank you for very interesting information!
It's also interesting that (as I understood), these specii normally manage without balloons (especially patterned ones) and only rare individuals carry this extra load. So, another hypothesis: it may be some kind of illness pathology, too (e.g. caused by viruses...). BTW, disease may affect pheromone-producing organs as well... This explanation fits all facts that I know at this moment...

I'm planning to prepare and post several photos of mating Lauxanids on which exposing of "abdominal hornlets" by females(! - if I'm not mistaken...) is clearly visible! :) But not right now, sorry... :(
