A Spider That Mimics An Ant,
On account of their poisonous stings, ants, bees and wasps are everywhere respected by predators and, consequently, serve as models for batesian mimics from insects as dissimilar as grasshoppers, mantids, bugs, moths, flies and beetles. Antmimics occur in a number of spider families including the Clubionidae, Gnaphosidae, crabspiders (Thomisidae), and jumpingspiders (Salticidae). In some cases, several different species of ants may be mimicked by the same species of Good mimics A few spiders mimic other animals, particularly ants. Ants are good animals to mimic because most predators avoid eating them. This is because ants are good at defending themselves. They live in large groups, and other ants will come to the aid of an ant that

is.attacked. Ants have a nasty bite, and they can spray acid at an enemy. They also taste bad. Some spiders smell and look like ants. Smell is the most important way that ants recognize each other. The spider's all the spiders that practise mimicry, by imitating bird droppings, ants, flies, beetles or parts of flowers. Some of them even mimic different ant species at different stages of growth. The Green Tree Ant of the tropics has three different spider mimics, so if imitation really is a form of flattery, that ant must be full of conceit. There are other spiders that look ordinary but do extraordinary things. Fishing Spiders skate over the water and catch fish, and some spiders live entirely by thieving from Some spiders

Some jumping spiders (genera Myrmarachne and Cosmo phasis, family Salticidae) are among the most perfect ant mimics. lumping spiders, Myrmarachne sp. (family Salticidae), mimic ants. An antlike sac spider, Micaria sp. (family Gnaphosidae). There are antlike sac spiders in The likeness presented varies considerably in degree from a general resemblance to several species, such as is seen in the Salticid spider IPtcJthamia pttata) of North America, toa close similarity to particular species. To this category belong Kfyrmarachtie plataUoidcs, one of

the.Salticidae, and Amyciaea forticeps, one of the Thomisidae which in India imitate and live with the vicious little red ant (Oecoptyiia smaragdina); also Myrmarackne provident, which mimics the red and black After some searching I discovered what I thought was another, but when I got it safely in a glass tube I found it was only an ant after all. How is a spider to look like an ant when an ant has a pair of antennae on its head and only six legs on its body, while a spider has eight legs and no antennae? How does a spider acquire the long slender waist of an ant? Spiders that mimic ants first of all become more elongated. Second, the front pair of legs are placed further forward than usual and the Attidae. These spiders,

antlike.in form, and partially antlike in habit, do not spin webs for the purpose of catching prey, but, wandering about in company with the ants they resemble, spring upon their victims from behind, (hence called by some Entomologists I have found these spider mimics in Orissa, and also in and near Calcutta, and have, during the last eighteen months, collected or acquired some eight or ten species or varieties belonging to genera of the subfamily Attidce.I have found these spider mimics in Orissa, and also in and near Calcutta, and have, during the last eighteen months, collected or acquired some eight or ten species or varieties belonging to genera of the subfamily Attidce. With one or two exceptions all these spiders were found hunting

with.the ants they so closely resemble. The two most common are a variety of Salticus fcrmicarius Linn, which mimics Sima rufonigra Jerd. and a pretty Salticus (sp. ?) which may be found in These spidors, antlike in form, and partially antlike in hahit, do not spin webs for the purpose of catching prey, but, wandering; about in company with the ants they resemble, spring upon their victims from behind, (hence called by some Entomologists Saltigradce) . Their home is While the body in most subfamilies of spiders is short and rounded with a constriction only between the cephalothorax and the abdomen, the mimic has a long thin body like that of an ant. There is a partial large number of spiders morphologically mimic ants for

various.reasons. Spiders are easily distinguishable, as they are not insects, but arachnids with four pairs of legs and eyes. Spiders of genus Myrmarachne are masters in disguise as they have a narrow body like an ant. They wave their first pair of legs above the head similar to an ant waving its antennae. The colour and the morphology causes a mistaken identity until the spider drops down by its silk. These spiders mimic ants
