Additional Remarks

Outward appearance closely resembles Castianeira variata; the two can be separated with a microscope exam of the reproductive organs (there are slight differences in pattern and coloration too, but typically only experienced arachnologists can tell the difference). The range of the two species overlaps in some places, but Castianeira longipalpa is more common and widespread.
Spider often mimics carpenter ants by slowly waving or “stroking” its front pair of legs in the air as if they were antennae. It will also slowly “nod” its abdomen up and down.
Egg sacs look like white, flattened discs that are attached to surfaces, and they don’t typically contain very many eggs (~10).
