Top Facts About Baby Jumping Spiders

12 Days of mating

The baby jumping spiders are from fertilized eggs laid by female jumping spiders after one up to 12 days after mating. The eggs are in the thick but fluffy sac with an enclosure at the top. The mother stays with the egg and guards to ensure safety until they hatch. It is incredible how they do not desire to eat from one week up to two weeks until their young ones hatch. The mother may stay longer to take care of the young ones or leave as soon as they hatch.

Got milk?

Among the arachnid members, the jumping spiders stand out. It is believed that their babies suckle milk though these spiders do not have breasts; the whitish liquid comes out through openings on her midsection area. They are the same openings that the female spiders use to lay eggs.

According to researchers, the milk is full of nutrients and is four times richer in proteins than cow milk. Other nutrients in the milk include fats and sugar. A single female spider lays a batch of eggs ranging between two and thirty-six. The tiny baby spiders feed on the milk droplets until they are little bigger and strong enough to suckle from the mother’s epigastric furrow. But in total, they are fed for 40 days and weaned.

20-day old baby jumping spiders are ready to leave their mother’s nest and find their food. They eat the food while still suckling until forty days are over. The survival rate of these insects’ young ones is 76%. The extended time for suckling helps them to survive. If you keep them at home, you should not cut them off the milk before 40 days are over. Those who leave the nest quickly and grow into adulthood tend to die early as adults compared to those who stayed with the mother until they were over 40 days old.

What do they eat?

While the jumping spiders feed their little ones on milk, it is under research to know what it is made of; scientists believe it compromises unfertilized milk. These spiders are not the first type of animals to feed their young with such eggs; the bees and frogs also do it. But these two lay the eggs, and their little ones eat them.
