They're all girls symbiotically attached to their plants/insects. Atrax for example is attached to one of the spider's legs, while Arachnocampa´s hair is connected to a huge worm, meanwhile Sera is just a girl who's surrounded by thousands of sticky barbs she uses to trap her prey. The only one who doesn't have a symbiotic relationship is Holeutea, she's an insect hybrid who hunts her prey by hiding in shadows.
