Appearance
Small, slender measuring 4–7 mm in length. Body deep black with long, slender bearing narrow edges on tergites. bullet-shaped with reddish . Legs stilt-like, elongated and slender. black. clear and membranous. with short bristles.
Habitat
Open, sunny including meadows, agricultural fields, bushy areas, and sparse vegetation. Strongly associated with leguminous plants. Also found along margins of sandy beaches. Requires vegetation structure that supports hunting and larval root-feeding development.
Distribution
to Europe and the Near East; and established in the . Recorded from Belgium, Denmark, Norway, and throughout most of Europe.
Seasonality
active from early June to early August. Peak activity during mid-summer months.
Diet
: predatory, feeding on small . : root-feeding, known to feed on roots of Pisum arvense (field pea), Trifolium pratense (red clover), and Medicago sativa (alfalfa).
Host Associations
- Pisum arvense - larval feed on roots
- Trifolium pratense - larval feed on roots
- Medicago sativa - larval feed on roots
Life Cycle
. Larval stage spent in soil feeding on roots, particularly of leguminous . in early summer, with period lasting approximately two months. Specific pupal stage details not documented.
Behavior
are active , hunting small in open vegetation. The elongated stilt-like legs are adapted for on vegetation surfaces and capturing . activity concentrated during mid-summer.
Ecological Role
function as of small , potentially contributing to pest suppression in agricultural . are root , primarily on leguminous and wild plants, with possible minor impacts on health in dense .
Human Relevance
Minor agricultural relevance due to larval root-feeding on cultivated legumes (pea, clover, alfalfa), though not considered a major pest. may provide incidental of small pests in fields and meadows.
