Exhausted Female Dragonfly in Energy-Saving Tandem Flight for Oviposition 240fps

A tandem pair of dragonfly (Sympetrum infuscatum, family Libellulidae) flying low over the mossy wetland to lay eggs. This female was unusual in that she barely flapped her wings during the tandem flight for oviposition. At first, I presumed she was sabotaging and wishing for a divorce. But you can clearly see in this 240-fps high-speed movie (or 8x slow-motion) that white tiny eggs were dropped one by one from the tip of her abdomen, just as usual. Was she too exhausted (or hungry) to fly? Captured at the wetland of river terrace on a sunny morning (10:46 AM) of late-August 2019 in Japan. The green moss was unidentified, but possibly juniper haircap (aka juniper polytrichum moss; Polytrichum juniperinum, family Polytrichaceae).
