Monocrepidius scissus
Peanut wireworm
Monocrepidius scissus is a click beetle in the Elateridae, commonly known as the peanut . The reflects its larval form's association with peanut , where wireworm larvae can cause damage to developing crops. are beetles with the characteristic body form of click beetles, capable of the jumping mechanism that gives the family its common name. The species has been documented across multiple observations, suggesting established in agricultural regions.

Identification
Distinguishing M. scissus from other Monocrepidius and related click beetles requires examination of specific morphological features not detailed in general sources. The "peanut " provides a contextual clue for identification in agricultural settings where this species occurs. Definitive identification likely requires examination of genitalia or other fine structural characters.
Appearance
have the elongated, parallel-sided body typical of Elateridae, with a pronotum that tapers posteriorly and fits into grooves on the mesosternum to enable the clicking mechanism. Body coloration and specific markings have not been documented in detail in available sources. Larvae are the form—elongate, cylindrical, hard-bodied, and yellowish to brownish with a heavily sclerotized .
Habitat
Associated with agricultural systems, particularly peanut . Larval includes soil where they develop as subterranean feeders. habitat includes fields and surrounding vegetation where they occur on plants or in soil litter.
Distribution
Distribution corresponds to regions where peanut agriculture occurs and where the has been documented through observation records. Specific range boundaries are not established in available sources.
Diet
Larvae feed on plant material in soil, including peanut pods and roots. Specific feeding habits are not documented.
Host Associations
- peanut - larval food plant reflects association; larvae feed on developing pods and roots
Life Cycle
Complete with , larval (), pupal, and stages. Larvae are the long-lived, soil-dwelling wireworm stage. Duration of developmental stages and number of larval instars have not been documented.
Behavior
possess the clicking/jumping mechanism characteristic of Elateridae, used for righting themselves when overturned and possibly for avoidance. Larvae move through soil in search of food resources.
Ecological Role
As a root-feeding larva, contributes to soil nutrient cycling through herbivory and . May serve as prey for soil-dwelling including birds, mammals, and predatory insects.
Human Relevance
Considered an agricultural pest due to larval damage to peanut crops. feeding on developing pods reduces yield and quality. Management may be required in infested fields.
