This is the dorsal view of the abdomen. The holes are probably for breathing purposes. Note the surface covered in minute hairs.
The spinnerets have produced a strand of silk even though she is stationary. She has a "lifeline" that keeps her in contact with her web should any catastrophe strike.
This species has a broad distribution as can be seen from their distribution map. Thanks to Graham for the info.

Female have an elongate ovipositor that they use to insert eggs into the ground in grassy areas. The following year the eggs hatch and the nymphs (hatchlings) are in just the right spot to take advantage of the small insects that live amongst developing grasses. Females are "dimorphic" for wing length. That is some individuals, like the one above, are fully capable of flight. Others are so short-winged that they can only glide.
