Garden symphylan

Definition

A small, white, centipede-like myriapod (Scutigerella immaculata, order Symphyla) that inhabits moist soil and decaying organic matter; a cosmopolitan agricultural pest that feeds on root hairs, germinating seeds, and young plant tissues, causing stunting or death in seedlings of vegetable crops, ornamentals, and greenhouse plants. Unlike true centipedes, symphylans lack venomous forcipules and possess 12 pairs of legs in adults, with a pair of spinnerets on the final trunk segment.

Etymology

From 'garden' (cultivated ground) + 'symphylan' (derived from Symphyla, the myriapod order, from Greek sym- 'together' + phylon 'tribe' or 'race')

Example

In coastal California strawberry fields, garden symphylan populations build up in fine-textured, high-organic-matter soils and can destroy entire plantings if not managed through soil flooding, deep tillage, or targeted bait applications.

Synonyms

• glasshouse symphylid
• Scutigerella immaculata

Related Terms

• Symphyla
• myriapod
• soil mesofauna
• root pest
• Centipede
• False wireworm

Usage Notes

Often confused with centipedes or wireworms by growers; distinguished by its smaller size (2–10 mm), lack of eyes, and rapid, snake-like movement when disturbed. The term 'symphylid' is sometimes used interchangeably but properly refers to the family level (Scutigerellidae). Populations are managed by monitoring with potato baits rather than direct observation.
