Lifecycle and Growth

Egg, Juvenile, Adult

3-6 weeks

Egg

Eggs are laid in a silk sac, providing protection as they develop into spiderlings ready to hatch.

Silk sac safeguards eggs
2-3 months

Juvenile

Juveniles emerge from eggs, resembling adults but smaller, gradually growing and shedding their exoskeleton through several molts.

Multiple molts for growth
1-2 years

Adult

Adults exhibit strong predatory skills, using large fangs to hunt woodlice and other small invertebrates in dark, damp spaces.

Skilled predator with large fangs

Dietary Habits

A nocturnal predator with specialized fangs, it primarily targets specific prey, using agility and stealth in its hunting approach.

DIET TYPEDESCRIPTION
Primary DietRegularly preys on woodlice, using its strong fangs to pierce the exoskeleton and consume the soft body.
Secondary DietOccasionally consumes other small arthropods like beetles or ants when its preferred prey is scarce.
OccasionalRarely eats small insects found in its environment, displaying flexibility in its diet under special conditions.

Frequently Asked Questions

How long do Woodlouse Spider live?

Woodlouse spiders typically live for about two years. They spend most of their life in damp environments where they can find their prey. Their lifespan may vary slightly based on environmental conditions and availability of food.

What do Woodlouse Spider eat?

Woodlouse spiders primarily feed on woodlice, which are small crustaceans found in moist habitats. They use their powerful fangs to pierce the exoskeleton of their prey. This specific diet gives them their name.

Are Woodlouse Spider poisonous?

Woodlouse spiders are venomous, but their venom is not dangerous to humans. Their bite might cause mild irritation and redness, similar to a bee sting, but it is not medically significant.

Are Woodlouse Spider endangered?

Woodlouse spiders are not considered endangered. They are commonly found across Europe and North America, thriving in a variety of habitats where their prey, woodlice, are abundant.

What do Woodlouse Spider symbolize?

Woodlouse spiders do not hold any significant symbolic meaning in most cultures. They are primarily noted for their role in controlling woodlice populations and their unique appearance.

Do Woodlouse Spider bite?

Yes, woodlouse spiders can bite if provoked. Their bite is not harmful to humans, causing only minor symptoms like redness and slight swelling. They prefer to avoid human interaction.

What color are Woodlouse Spider?

Woodlouse spiders are reddish-brown with a shiny, dark brown abdomen. Their distinctive coloration helps them blend into their natural environment, such as leaf litter and under rocks.

Does a Woodlouse Spider have wings?

No, woodlouse spiders do not have wings. They are ground-dwelling creatures that rely on their agility and speed to catch prey. Like most spiders, they use silk for making retreats rather than for flight.

What does a Woodlouse Spider look like?

A woodlouse spider has a reddish-brown cephalothorax, dark brown abdomen, and long, robust legs. They are medium-sized, with their body length ranging from 10 to 15 millimeters. Their large fangs are notable features.

Is a Woodlouse Spider an insect?

No, a woodlouse spider is not an insect. It is an arachnid, which is a class of joint-legged invertebrates that also includes scorpions, ticks, and mites. Unlike insects, spiders have eight legs and two main body segments.
