1, pig excrement beans mainly feed on insects, other spiders and multi-legged animals.
2. Four-spined Crops can dive close to catch prey within 30 cm and pounce on it.
3. Before the female spider lays eggs, make a "puerperal" with silk. Lay eggs on it and cover it with silk. And weave the egg bag into a fixed shape.
4. Female spiders only produce one egg bag, and some also produce multiple egg bags. The young spiders hatched from the egg shell are still in the egg bag, and they have to molt in the egg bag 1 time before leaving the egg bag.
5. Before the mature period, the pig excrement bean will molt several times with its growth, and the molting times and intervals are quite inconsistent.
