![]() ![]() Transfers of larvae from spider to spider are possible during spider mating or cannibalism. Larvae maintain themselves aboard spiders by feeding on spider hemolymph. Mantispids that board spiders usually adopt positions on or near the pedicel some species may enter the spider's book lungs. įirst-instar mantispids use two strategies to locate spider eggs: larvae may burrow directly through the silk of egg sacs they find, or they may board and be carried by female spiders prior to sac production ( phoresy), entering the sac as it is being constructed. Mantispinae have the most specialized larval development among all mantidflies studied to date (the life history of the Drepanicinae remains unknown): their campodeiform larvae seek out female spiders or their egg sacs which they then enter the scarabaeiform larvae then feed on the spider eggs, draining egg contents through a piercing/sucking tube formed by modified mandibles and maxillae, pupating in the egg sac. Larvae of the Calomantispinae are predators of small arthropods, and in at least one species they are mobile. Symphrasinae larvae are sedentary parasitoids on bee, wasp or scarab beetle larvae. Mantidflies are active hunters, but as with other Neuroptera, they are cumbersome fliers. However, the underlying mechanisms for the prey capture behavior are different in mantidflies and mantids. ![]() Adult mantidflies are predators of suitably sized insects, which they catch as mantids do. They are usually green, brown, yellow, and sometimes pink, and have four membranous wings which may sometimes be patterned (especially in wasp mimicking species) but are usually clear. The adults are predatory insects that are often nocturnal, and are sometimes attracted by porch lights or blacklights. The vernacular and scientific names are derived from their mantis-like appearance, as their spiny " raptorial" front legs are modified to catch small insect prey and are very similar to the front legs of mantids (the only difference is that the pincers lack footpads and are not used for walking at all). As their names suggest, members of the group possess raptorial forelimbs similar to those of the praying mantis, a case of convergent evolution.ĭescription and ecology Head of a mantisfly in genus Plega Campion sp., Sydney, Australia A Sagittalata species female from Kerala, IndiaĪbout 5–47 mm (0.20–1.85 in) long and with a wingspan of 5–30 mm (0.2–1.2 in), some mantidflies such as Climaciella brunnea, Euclimacia nodosa are wasp mimics, but most are brownish with green, yellow and sometimes red hues. Only five species of Mantispa occur in Europe. There are many genera with around 400 species worldwide, especially in the tropics and subtropics. 5).Mantispidae, known commonly as mantidflies, mantispids, mantid lacewings, mantisflies or mantis-flies, is a family of small to moderate-sized insects in the order Neuroptera. Occasionally, mantids will display a defensive behavior if threatened by a larger animal (Fig. This allows mantids to sit on twigs or stems and wait to ambush prey as they pass by. ![]() Most mantids blend into the background and will camoflage themselves with plant material. Adult mantids have wings, but are clumsy flyers some species have females with reduced wings and rarely fly. Both the nymphs and adults are predatory and will attempt to eat any insect or arthropod. The forelegs strike out and capture prey, and sharp leg spines hold the prey while being crushed by powerful chewing mouthparts. But probably the most recognizable body feature is the grasping forelegs, folded under the thorax in a “praying” gesture (Figs. Mantids can literally look over their shoulders because of a flexible neck and have a large field of vision. Mantids are easily distinguished from other insects because of their large, triangular head and obvious compound eyes (Fig. This cannibalistic mating habit probably ensures the female will have enough energy to deposit her oothecae, and this could be seen as “suicide” or a nuptial gift. Males quickly try to maneuver themselves on the females back to successfully mate, but sometimes get eaten anyway. Male mantids are cautionary when approaching females and try to ambush females without being attacked. Nymphs mature into adults later in the summer.Īdults have an unusual mating behavior, where the females will attempt to eat the male before, during or after copulation. Often, mantids are cannibalistic and will eat siblings. In the spring, nymphs will emerge from the ootheca and immediately begin to look for food. Oothecae harden on branches, rocks, or other structures, and are the overwintering stage. In the fall, mated females will deposit 12-400 eggs in a frothy protective egg case called an ootheca (Fig. Mantids are closely related to grasshoppers, crickets and katydids, and go through simple or incomplete metamorphosis (Fig. Images courtesy of Whitney Cranshaw, Colorado State University Extension.
