An external source lists the HORNWORM, which actually is not a worm at all nor is it dangerous to humans, but rather a caterpillar, (Manduca quinguemaculata) that notably sports a long, horn-like protrusion from its posterior…「netting wrapped around larva」describes the cocoons that caterpillars weave in which to metamorphose from the pupa stage into a moth or a butterfly. COCOONS generally are FIRMLY ATTACHED to twigs or other objects.「Netting wrapped around pathogens, corkscrew demons, loose dripping from orifice, the snake」as the result frankly of human beings sporting various long, horn-like green rod protrusions from various posteriors and wrapped in a poultice, in that sense equating humans to hornworms as it were, who actually are slimy, worm-like, and dangerous to other humans.
「Netting, head wrapped with bugs」may also refer to a groin poultice teeming with PUBIC CRABS, blood-sucking parasites. A「network of worms hooked between spread legs」refers INTESTINAL PARASITES that are also FIRMLY ATTACHED, CONNECTED, such as tapeworms, flatworms, pinworms, roundworms, whipworms, or hookworms. Intestinal parasites were a common problem 10,000 years ago when many folks snacked on raw meat and walked around barefoot, and are a common problem today since many folks still snack on undercooked meat and walk around barefoot, such as children:
「There are a vast number of worms that can live within the human body. The worms live in the digestive tract, especially in the intestines, from where they obtain their nutrition. Hence, worms are parasites living within the body of humans, who are the hosts. …Worm infestations are present in people of all ages but they are much more of a problem in children who are just beginning to learn to cope with their parasitic enemies. …Intestinal worms, quite simply put, are worms that live within the intestines of humans. These are parasitic worms which feed on the food that passes through the human digestive tract. All these worms spend their entire lifetimes in the intestines of humans. They breed within the intestines and hence increase their populations. The worms have hook-like attachments on their heads (called a 'scolex') by which they attach onto the inner lining of the intestines. Though worms are generally found in the intestines, they can also be found within the stomach and the rectum. …Worms [were, 100 years ago] present in the intestines of all human beings.」

「Networking」「hooked snakes」or「skin slit for head and neck, vulva short leg two ways, two sides」for both genital regions meaning FIRMLY ATTACHED, CONNECTED. Snakes have vestigial hind legs, claw-like appendages that are held「inside」around the cloaca, the orifice used for copulation, called「anal spurs」barbs with which the female snake FIRMLY ATTACHES herself to the skin of the male snake during reproduction. The male snake possesses the same inner barbs but also has forked hemipenes (a「short leg with two sides」) normally held inside the body, and also attaches barbs to the inside walls of the female's cloaca, the snake's equivalent to a vagina. Hemipenes are half-open penises, with semen troughs exposed, so this FIRM INSIDE CONNECTION and ATTACHMENT FROM BOTH SIDES is vital. Thus,「repeated copulations among snake genitals, cloaca and hemipenes」are FIRMLY ATTACHED and CONNECTED. Furthermore, while the male snake possesses a forked penis, note that he normally does not copulate with two females simultaneously, a fantasy reserved for human males and bonobos, it seems. Further, this glyph is apparently unrelated to silk-spinning caterpillars, despite what some sources say.
