Anoeciinae

Anoeciinae can be distinguished from other aphid subfamilies by their exclusively subterranean habit and association with plant roots. Morphological features include reduced or absent wings in most life stages and adaptations for soil-dwelling. Identification to genus requires examination of specific morphological characters such as antennal and caudal structures.

Strictly subterranean; found in soil associated with plant root systems. Occurs in various soil types supporting host plants.

Worldwide distribution where host plants occur; specific range limited by suitable soil conditions and presence of compatible host roots.

Feeds on phloem sap of plant roots. Host plants include various herbaceous species and grasses.

Obligate subterranean existence throughout the life cycle. Does not produce aerial forms or alternate between hosts.

Root-feeding herbivore; may influence plant root physiology and nutrient cycling in soil ecosystems.

Potential minor agricultural pest through root feeding on crop plants; generally of limited economic significance compared to above-ground aphids.

• EriosomatinaeAlso contains root-feeding aphids; distinguished by different gall-forming behaviors on primary hosts and distinct morphological features
• AphidinaeMostly above-ground feeders; distinguished by aerial habit, often with complex host alternation
