Mantispidae is a of neuropteran insects comprising approximately 400 in around 400 , distributed worldwide with highest diversity in tropical and subtropical regions. are characterized by forelegs—convergent with mantises but independently evolved—used to capture small prey. The family exhibits diverse larval : Mantispinae are ectoparasitoids of spider sacs; Symphrasinae parasitize ground-nesting hymenopterans and scarab beetle larvae; Calomantispinae are predatory on small arthropods; and Drepanicinae life history remains largely unknown. First-instar larvae () employ specialized -location strategies including direct penetration of egg sacs or phoretic transport on female spiders.

Identification

distinguished from mantises (Mantodea) by possession of four membranous wings (vs. two pairs with tegmina in mantises), shorter , and different wing venation. forelegs lack tarsal pads and are not used for . Body length 5–47 mm, wingspan 5–30 mm. Some (e.g., Climaciella brunnea) exhibit mimicry with constricted "wasp waist," wings folded longitudinally over back, and darkened leading wing margins. From other Neuroptera, distinguished by elongated prothorax and raptorial forelegs. Larvae: campodeiform first instars () with active -seeking ; subsequent instars scarabaeiform and either ectoparasitic or endoparasitic depending on .

Habitat

occur in diverse terrestrial including woodlands, grasslands, and scrublands; frequently associated with flowering vegetation where they hunt. Larval habitat varies by : Mantispinae require proximity to spider ; Symphrasinae associated with ground-nesting , , or scarab beetle burrows; Calomantispinae in ground litter or soil where small prey occurs; Drepanicinae unknown but adults emerge from pupae attached to tree trunks in moist or forested habitats.

Distribution

on all continents except Antarctica. Highest in Australia and the Americas (especially tropics and subtropics). In Europe, only five of Mantispa occur. In North America, widely distributed with Climaciella brunnea recorded from southern Canada through most of the United States (except Pacific coast states, Idaho, and Nevada) south to Rica. Amazon Basin contains 27 described species. Colombia documented with 26 species; Panama with 19 species.

Seasonality

activity varies by and latitude. Climaciella brunnea adults emerge May through October, with peak abundance June–August. Adults of many species and attracted to ultraviolet lights or porch lights. Males of some species short-lived (less than one week); females persist approximately one month.

Diet

are active capturing suitably sized insects using forelegs; prey includes small soft-bodied arthropods such as aphids and other insects encountered on flowers. Larvae are or predators depending on : Mantispinae feed exclusively on spider ; Symphrasinae parasitize larvae of ground-nesting Hymenoptera (bees, ) or scarab beetles; Calomantispinae are predatory on small arthropods.

Host Associations

Life Cycle

Hypermetamorphic development with distinct larval phases. deposited on vegetation in clusters of hundreds to thousands on short stalks. First-instar larvae () are campodeiform (elongate, active) and seek using two primary strategies: direct penetration of spider egg sacs through silk, or phoretic transport by boarding female spiders and entering egg sacs during construction. Planidia maintain themselves on spiders by feeding on . Once inside egg sacs or host nests, larvae transform to scarabaeiform (-like) ectoparasitic or endoparasitic instars that feed on host eggs or larvae through formed by modified and . occurs within host remains or in soil. Developmental time from to approximately 24 days in Mantispa viridis; entire requires at least one year.

Behavior

are sit-and-wait or active ; some . When disturbed, -mimicking species (e.g., Climaciella brunnea) adopt defensive postures with wings splayed like agitated paper wasps. Larvae exhibit sophisticated -finding : phoretic position themselves on or near the spider , with some species entering book lungs; transfers between spiders occur during mating or . Adults frequently groom their forelegs.

Ecological Role

of spiders through ; regulation of ground-nesting hymenopteran and scarab beetle . contributes to general population control. Complex ecological interactions include potential for larvae to influence spider reproductive and .

Human Relevance

Generally beneficial as agents of spiders and other arthropods. Occasionally attracted to artificial lights. -mimicking may cause initial alarm due to resemblance to stinging insects, but are harmless to humans. Some species (e.g., Climaciella brunnea) are subjects of scientific interest due to remarkable mimicry and complex .
