Typical Size Range
Adult females measure between 5 to 10 mm in body length, with a total leg span reaching around 25 mm. Males are slightly smaller but similar in appearance.
5. Goldenrod Crab Spider
The Goldenrod Crab Spider is well-known for its ability to change color between white and yellow to match the flower it’s hiding on, usually goldenrod or daisies. It’s a sit-and-wait predator that ambushes prey rather than spinning webs.
Identification Features
- Crab-like stance and body shape
- Broad, flat body
- Two front legs longer than the others
- Smooth, glossy abdomen
- No web structure
Natural Habitat
This spider is found on flowering plants in fields, gardens, and meadows. It stays on top of flower petals, especially goldenrods, sunflowers, and daisies, where it waits for insects to land. Its natural camouflage helps it remain hidden from both prey and predators.
Body Color
Females can appear bright yellow when sitting on yellow flowers, but they may also turn white or pale green. The ability to shift between white and yellow tones makes them well-camouflaged. Males are smaller and typically darker, with reddish markings.
Typical Size Range
Females can grow up to 10 mm in body length, while males are much smaller, usually around 3 to 4 mm. The front legs are often longer than the body, giving them a wider overall span.
6. Yellow Orb-Weaver Spider
The Yellow Orb-Weaver Spider is a member of the Araneidae family, known for building classic round webs in gardens and forests. These spiders vary in appearance, but many have yellow coloration on their abdomens, often mixed with white, orange, or brown patterns.
Identification Features
- Round or oval-shaped abdomen
- Yellow coloration, sometimes with stripes or spots
- Short, sturdy legs with bands or markings
- Large, symmetrical web structure
- Typically hangs head-down in center of web
Natural Habitat
These spiders are often found in gardens, wooded areas, parks, and meadows. They prefer quiet spots where their large webs won’t be disturbed. The web is usually built between plants, branches, or even man-made structures like fences.
Body Color
The abdomen may be bright yellow with brown or black patterns, depending on species. Some orb-weavers appear almost golden in the sunlight. Their coloration helps them blend in with flowers or foliage, or to act as a lure for flying insects.
Typical Size Range
Females can reach up to 20 mm in body length, while males are significantly smaller, often around 5–8 mm. The overall leg span can exceed 40 mm in large individuals.
7. Neon Yellow Jumping Spider
The Neon Yellow Jumping Spider is a visually striking species that belongs to the Salticidae family. It’s rare and not widely documented, but certain jumping spiders exhibit vivid yellow or greenish-yellow coloring, especially in tropical and subtropical regions.
Identification Features
- Compact body shape
- Short, strong legs with hairy surfaces
- Large front eyes for excellent vision
- Bright yellow or neon green body
