「Repeated insects inside stretched skin, sail」is caused by the WIND…with no wind blowing, insects are not pushed against an open sail and held within trapping some flying insects. Strong wind patterns can blow in repeated infestations year after year of insects.「An array of insects thrusting forward straight at you」could easily be caused by the WIND. Many species of mites and similarly sized animals in fact migrate via wind dispersal to new regions:「Night-flying moths will continue flying during the day if they find themselves over water, while wingless mites can adjust their body posture to modify their rate of ascent and descent through the air, and thus their dispersal distance. The greasy cutworm has become magnificently adapted to migrate northwards for over 1,600 km each northern spring, then return against the prevailing winds the following autumn. The extent of these migrations defied the imaginations of many early researchers, who fruitlessly dug up ground in the northern United States searching for overwintering cutworm caterpillars, while in reality the moths were enjoying warmer climes nearly 2,000 km to the south. Monarch butterflies make similar annual migrations between Canada and Mexico, a distance of over 3,600 km. …[A]erial nets in China…found numerous insects, fungi, pollen, seeds and spiders were present in the air, and it's notable that less than one percent of the arthropods they caught were moths or butterflies. Another surprising feature of the published data is that a large proportion of airborne organisms are found at relatively low altitudes of around 100–300 m. The idea that…travellers are unlikely to survive the ravages of high altitude, cold and strong winds may not be generally true. Organisms exploit the wind for dispersing to new regions and finding new habitats, and the success of this strategy is evidenced by its prevalence in nature. …Not only do diverse organisms disperse through the air, but they can do so in abundance. Using radar and aerial nets, Riley et al (1995) monitored airborne organisms and estimated that in each cubic hectare of air there were 500,000 aphids, 100,000 brown plant hoppers, 1,000 spruce budworms, 2,000–3,000 corn earworms and fall armyworms, and 700 rice leaf rollers.」

「Erect」with「louse, crabs, lice」as SKIN ERUPTIONS due to insect bites. Outer elements of「stiff and swift forward lateral movement」with internal elements of「repeated」or「wide array」over「vulva and short leg, snake, worms, larvae」that describes both groin regions where a pubic louse attaches eggs, called a 'nit,' to pubic hairs. The MANNER or CUSTOM of picking off the larva from oneself or from a partner gave rise to the English term 'nit-picking.' In Japanese, this glyph also refers to running around naked, rather common behavior of young children today and just about everybody else too long ago, UNFETTERED, SWINGING LOOSELY and FREE FLOWING as an unequivocal sexual reference and the common MANNER, STYLE, or CUSTOM.
Might also refer to an individual's own FORM, MANNER, STYLE, or CUSTOM of becoming「erect and forward thrusting motions repeatedly in vulva with snake-like short leg」as the elements literally suggest: see 凮 with identical meanings.
In Japanese, also meaning a FOLK SONG, and「erection with infestation in orifice vent of rod with loose dripping cloud of rancid stench and repeated head bobbing continuously with bird flapping and thrusting laterally」describes the approach of a man with a sad case of telltale gonorrhea, detected by his obvious malodour, so that THE ANSWER MY FRIEND IS BLOWING IN THE WIND to the question of,「does he, or doesn't he?」(not only his witch doctor knows for sure…), the stuff of fundaments that folk songs are made of.
