The female spider is the only one who provides food and care and for the babies as males of these species take no part in child-rearing.

What is their conservation status?

Grass spiders are found all over North America and parts of Canada in abundance and are often considered pests. But since they play an important role in the ecosystem by eliminating small insects by preying on them as a food source, they are often left alone unless there is a case of an infestation.
