Summary

Procampodeidae is a single genus within the order Diplura, characterized by their lack of eyes, short body size, unique cerci, and ecological role in moist soils. They are part of the Entognatha class and practice external fertilisation.

Physical Characteristics

Diplurans are typically 2–50 millimetres long, with most species falling between 7 and 10 millimetres. They have no eyes, are unpigmented except for some darkened cerci, and possess long antennae with 10 or more bead-like segments. The body segments may display several types of setae or scales. The abdomen has eversible vesicles for moisture absorption and bears a characteristic pair of cerci which may be long and filamentous or short and pincer-like.

Identification Tips

Diplurans can be identified by their lack of eyes, the presence of long, segmented antennae, and the distinctive pair of cerci at the end of the abdomen. Their size and body structure can lead to confusion with earwigs, but diplurans lack wings and are entirely unpigmented.

Habitat

Diplurans are typically found in moist soil, leaf litter, or humus, often living a subterranean lifestyle.

Distribution

Diplurans are distributed across almost all land masses, except for Antarctica and some oceanic islands.

Diet

Diplurans feed on a variety of live prey, dead organic matter, and some herbivorous species consume plant material.

Life Cycle

Moulting occurs up to 30 times throughout the life of a dipluran, which is estimated to last up to one year. Hatchlings resemble adults but are smaller and lack reproductive organs.

Reproduction

Diplurans practice external fertilisation. Males produce up to 200 spermatophores a week, which are collected by females to fertilise their eggs laid in ground cavities.

Ecosystem Role

Diplurans play a vital role in soil ecology, indicating soil quality and responding to anthropogenic impacts such as soil nutrient depletion.

Evolution

The relationships among the groups of hexapods, including Diplura, are not entirely resolved, with some studies arguing against a monophyletic Entognatha. The fossil record of Diplura is sparse, with some evidence from the Carboniferous period.

Misconceptions

Diplurans can sometimes be mistaken for earwigs due to their cerci, but they lack the distinctive wings and eyes of earwigs.
