O, the work that goes into one of these! It's heroic.
Micrathena, perhaps M. sagittata, the arrow-shaped micrathena, is a woodland orb-weaver; and by the tightness of the warp and weft, she's a specialist.
My grandmother Pearl, who knew her way around a loom, would have been envious of her craftswomanship.
The name comes from the prefix Micro- meaning "small" and Athena, the Greek goddess of heroic endeavour who wore armor and was also a superb weaver. Perfect moniker.
