Flecked Jumping Spider
Evarcha falcata
Salticidae (Jumping Spiders), Order Araneae. Key family characteristics include large anterior median eyes and complex hunting behaviors.
Physical Description
A compact, robust spider with a high cephalothorax. The body is covered in dense, short hairs (setae). Males typically have a dark face with a light band above the eyes, while females are more mottled. The abdomen is oval-shaped and slightly flattened.
Size Estimate
Small; body length typically ranges from 5 to 8 mm. This specimen appears to be an adult based on the well-defined ocular region and developed pedipalps.
Coloration & Markings
Features a mix of copper, bronze, and dark brown scales. The cephalothorax often has a light tan or whitish band behind the eyes. The abdomen displays a 'flecked' pattern of dark spots on a lighter brownish-gold background.
Web Type
Hunting spider; does not weave a web to capture prey. It uses silk only to build 'pup-tents' or silken retreats for molting, mating, and sleeping.
Eye Arrangement
Distinctive Salticid pattern: 8 eyes total. The front row has 4 eyes with two massive Anterior Median Eyes (AME) providing high-resolution vision, flanked by two smaller Anterior Lateral Eyes (ALE). The remaining four eyes sit on top of the head.
Leg Characteristics
Strong, stout legs designed for jumping rather than running. All legs are covered in fine hairs and spines. The front pair is slightly thicker, used for grabbing prey upon landing.
Venom & Safety Information
Venom Information
Contains complex proteins used to paralyze small insects. The venom is not considered medically significant to humans; the volume is tiny and the toxicity level for mammals is very low.
Medical Significance
Harmless. Bites are extremely rare as the spider is timid and its fangs often cannot penetrate human skin. If a bite occurs, it usually results in localized redness or itching equivalent to a mild bee sting.
Safety Recommendations
No special safety measures required. If found indoors, they can be easily relocated by placing a cup over them and sliding a piece of paper underneath.
Habitat & Behavior
Habitat & Range
Common throughout the Palearctic region (Europe, North Asia, and Japan). Prefers sunny edges of forests, low-growing vegetation, heaths, and sunny garden shrubs.
Behavior & Temperament
Extremely curious and active during daylight. They are expert stalkers that use hydraulic pressure to leap many times their body length. They are generally calm and will jump away or hide if threatened by humans.
Diet & Prey
Generalist carnivore feeding on small insects such as flies, aphids, and small moths. They stalk prey like a cat and pounce from a distance, using a silk 'safety line' to tether themselves.
Seasonal Activity
Most active from late spring through late summer. Males are often seen 'dancing' to attract females during the warmer months of May and June.
Description
The Flecked Jumping Spider is a charismatic micro-predator of the garden. With its huge 'puppy-dog' eyes and jerky, inquisitive movements, it is often cited as the most approachable spider for those with arachnophobia.
Key Features
Huge central eyes, bronze/copper metallic sheen on the cephalothorax, and a 'mask-like' pattern around the ocular quad.
Similar Species
Evarcha arcuata (Heath Jumping Spider), which is darker and prefers wetter habitats; also Salticus scenicus (Zebra Spider) which has distinct black and white stripes.
Life Cycle
Females lay eggs in a silken sac hidden within folded leaves or under bark. They often guard the sac until the spiderlings emerge. Life span is typically 1 to 2 years.
Ecological Importance
Vital for natural pest control in gardens and forests, keeping populations of flies and leaf-damaging insects in check.
Conservation Status
Not listed by the IUCN; generally considered common and widespread with stable populations in suitable habitats.
Interesting Facts
Jumping spiders have vision that is, in some respects, better than a cat's. They can see in color and have incredible depth perception despite their tiny size.
Photography Tips
Focus strictly on the large front eyes. Use a high shutter speed or flash to freeze their fast, jerky movements. Getting at eye-level with the spider creates the most engaging and identifying portraits.
