Marbled orb-weaver facts tell us about their webs.

Spiders may be scary but here we will introduce you to a beautiful-looking spider, who is rather very cute. The marbled orb-weaver (Araneus marmoreus) is a kind of spider that is famous for its oval-shaped abdomen and beautiful patterns.

They have marble-like patterns of white, yellow, black, and orange. Their habitat includes fields, forests, shrubs, and suburban areas in North America, North Asia, and Europe.

These spiders hatch from their eggs in the spring and reach maturity in the summer. Hence, the mating season of the spiders also arrives in the summer.

They eat all kinds of insects, and they don't go foraging for them. They make traps for their prey and wait for them by hiding nearby.

The spiders breed in a large number and don't have any great threat, so there is an abundance of them. The little venom they have also doesn't hurt humans, so they don't possess any harm to us.

The spiders live for only about six months. The eggs hatch in the spring and by the next fall, they reach sexual maturity, so they mate and then die.

How do they reproduce?

The mating season for marbled orb-weavers comes in the summer. The exact reproductive behavior of the species has not been researched in a broader sense, but we can assume the nature of their reproduction from other spiders of the Araneus genus.

The adults of the female spiders of the genus release pheromone to attract mates. The adults of the male spiders spin a mating thread at the web of the female.

Then the male walks across that thread towards the female, and the female starts to advance toward the male.

The spiders of the genus show the nature of sexual cannibalism, but a male marbled orb-weaver is known to mate quite a few times in their lifetime, so it's very much possible that this species of spider doesn't show cannibalistic traits. The females make egg sacs with silk and lay their eggs in them.

There may be several hundred eggs in one egg sac. The eggs hatch from the egg sacs in the spring and go through many instars molting and growing until the summer when they become adults.

What is their conservation status?

The conservation status of the spiders is Not Listed under the International Union for Conservation of Nature. We can only assume that they are not endangered or the species is not in any way threatened currently.

These spiders are polymorphic and have oval-shaped abdomens. The females of the species are also larger than the males.

According to the colors and patterns on their abdomen, there are two forms present among the species of spiders - 'variation pyramidatus' and 'nominate marmoreus'. Both variations have white, yellow, and orange to the light brown abdomen with white, black, and grey patterns on them.

Their legs also have striped patterns of white, black, and clear colors. The only distinctive quality between the two variations is that the variation pyramidatus has a brown-colored mark at the end of their paler than usual abdomen.

These spiders communicate visually, chemically, and through vibrations. The spiders have tactile hair on their body which can sense vibrations in their surroundings to help them figure out what is causing the vibration and from which direction it's coming.

Other species of the same genus release pheromones in order to find mates. We can surely assume that the female marbled orb-weaver spiders also do the same.

Marbled orb-weavers eat all kinds of insects that are smaller than them, mainly from the Hymenoptera, Diptera, and Orthoptera orders. They have a distinctive way of catching prey.

They build their webs to catch their prey, then they attach a silk thread which is the signal thread from the side of the web to them. When prey gets stuck in the webs, the signal thread vibrates and lets the spider know.

Then the spider comes out of its hiding spot and attacks the prey. This method also helps the spider hide from predators.
