Facts about White Flower Spiders, "Scientific name for White Flower Spider is Thomisus spectabilis". A White Flower Spider is called as crab spider at times because of its crab like stout legs. They are mostly seen in white and yellow color. Some of the White Flower Spider might have green, brown or reddish tints on their abdomen.
The female White Flower Spider are bigger in comparison to the males, but have smaller legs. They have two eyes in the front end of their abdomen having well developed eyesight. This enables the White Flower Spider to trace their prey even in night.
Habitat of White Flower Spiders
White Flower Spiders are the main hunting territories for them. A white flower spider selects a flower as its territory and waits for its prey on the petals by using its legs as anchor. The spider seizes the prey and bites to paralyse it. When the prey loses its mobility, the White Flower Spider sucks it dry.
White flower spiders are diurnal (that means they roam and hunt during the day) and commonly seen in summer. They are abundantly seen in gardens having native flowers, grass heads and bushes.
Prey of White Flower Spiders
All the insects that get attracted to the nectar fall prey to white flower spider. It catches butterflies and other nectar feeding insects with its front legs and bites them to death.
Breeding of White Flower Spiders
When the white flower female spider is ready to lay eggs, it makes a dish like structure out of the fine thread it secretes from its mouth. It lays eggs on it and makes a silk lid on the disk. The eggs hatch after two weeks and newborns are left for feeding themselves.
Venom of White Flower Spider
The white flower spider is very reflexive. It bites in no time and disappears releasing a venom that causes severe local pain to humans. It usually takes a couple of days to recover fully from the wound and pain.
One species of this spider is known as Goldenrod due to its ability to change its color to yellow to hide in yellow color flowers.
Spiders belong to a group of animals called "arachnids", mites and Scorpions and a tick is also in the arachnid family. An Arachnids is a creature with eight legs, two body parts, no antennae or wings and are not able to chew on food. Spiders are not insects because insects have three main body parts and six legs and most insects have wings.
The Arachnids are even in a larger group of animals called "arthropods" an invertebrate animal of the large phylum Arthropoda, which also include spiders, crustaceans and insects. They are the largest group in the animal world, about 80% of all animals come from this group. There are over a million different species. There are more than 40,000 different types of spiders in the world.
White Flower Spiders do not have a skeletons. They have a hard outer shell called an exoskeleton-(a rigid external covering for the body in some invertebrate animals). The exoskeleton is hard, so it can’t grow with the spider. The young White Flower Spiders need to shed their exoskeleton. The spider has to climb out of the old shell through the cephalothorax. Once out, they must spread themselves out before the new exoskeleton will harden. Know they have some room to grow. They stop growing once they fill this shell. Female White Flower Spiders are usually bigger than males.
Female White Flower Spiders lay eggs on a bed of silk, which she creates right after mating. Once the female White Flower Spider lays her eggs, she will than cover them with more silk.
White Flower Spiders have oversize brains.
In the White Flower Spider the oxygen is bound to "hemocyanin" a copper-based protein that turns their blood blue, a molecule that contains copper rather than iron. Iron-based hemoglobin in red blood cells turns the blood red
White Flower Spiders have two body parts, the front part of the body is called the Cephalothorax-(the thorax and fused head of spiders). Also on this part of the body is the White Flower Spider’s gland that makes the poison and the stomach, fangs, mouth, legs, eyes and brain. White Flower Spiders also have these tiny little leg-type things called (pedipalps) that are next to the fangs. They are used to hold food while the spider bites it. The next part of the White Flower Spiders body is the abdomen and the abdomens back end is where there is the spinnerets and where the silk producing glands are located.
The muscles in a White Flower Spiders legs pull them inward, but the spider can't extend its legs outward. It will pump a watery liquid into its legs that pushes them out. A White Flower Spider’s legs and body are covered with lots of hair and these hairs are water-repellent, which trap a thin layer of air around the body so the White Flower Spiders body doesn't get wet. It allows them to float, this is how some spiders can survive under water for hours. A White Flower Spider feels its prey with chemo sensitive hairs on its legs and than feels if the prey is edible. The leg hair picks up smells and vibrations from the air. There are at minimum, two small claws that are at the end of the legs. Each White Flower Spiders leg has six joints, giving the spider 48 leg joints. The spider’s body has oil on it, so the spider doesn't stick to it’s own web.
A White Flower Spiders stomach can only take liquids, so a spider needs to liquefy their food before they eat. They bite on their prey and empty its stomach liquids into the pray which turns it into a soup for them to drink.
A male White Flower Spider has two appendages called "pedipalps" a sensory organ, instead of a penis, which is filled with sperm and insert by the male into the female White Flower Spider’s reproductive opening.
