Nidicolous

Definition

Remaining in the nest or parental dwelling for a substantial period after hatching or birth, depending on parental provisioning and protection until sufficiently developed to leave. Contrasts with nidifugous, in which offspring depart shortly after emergence. The distinction, borrowed from ornithology, applies to arthropods whose young exhibit extended post-hatching residence in constructed or occupied shelters.

Etymology

From Latin nidus (nest) + colere (to inhabit, dwell)

Example

Carpoglyphus nidicolous, a mite named for this habit, inhabits nests alongside its hosts; similarly, some social insect larvae remain in brood cells receiving extended care, exhibiting nidicolous development.

Related Terms

• nidifugous
• altricial
• precocial
• brood care
• Parental investment

Usage Notes

Primarily an ornithological term now extended to arthropod biology. Use implies dependence on parental or nest-associated resources for survival; does not specify duration. Contrast with nidifugous is relative—some species show intermediate patterns. In entomology, often implicit in descriptions of subsocial or eusocial development without being explicitly labeled.
