So here's an absolutely amazing little critter (thanks Bill Yule!!), the larva of a fungus gnat, but not Leptomorphus sp. as I originally thought. This one is more likely from the family Keroplatidae (Thanks, Suhaib Firdous Yatoo!). A bunch of these guys are spore eaters, primarily of those produced by polypores and resupinate crust fungi. This one has made its home on the pore-pocked underside of a Tinder Polypore (Fomes excavatus). At night, it spins a web that covers the entire pore surface of the mushroom, a web so fine it gleams like cellophane (or slug slime!). This web catches falling spores which, during the day, the larva consumes along with bits of the web, and then repairs the parts it eats so that more spores can be trapped. Maggot of the week!
