Trawl-line spider (Egg sac)
Allocyclosa bifurca
- Order & Family
- Araneae: Araneidae
- Size
- Egg sacs are approximately 3-5mm in diameter; adult females reach 6-9mm in length.
Natural Habitat
Typically found in coastal forests, wetlands, and subtropical gardens across the southeastern United States and South America.
Diet & Feeding
Strictly carnivorous, feeding on various small flying insects such as mosquitoes, flies, and gnats trapped in its orb web.
Behavior Patterns
The spider creates a unique 'trawl-line' of silk where it hangs its egg sacs and attaches remnants of prey. This creates a vertical line of debris that serves as camouflaged decoys to trick predators.
Risks & Benefits
Generally harmless to humans and lacks significant venom. Beneficial to the ecosystem as they provide natural pest control by consuming winged insects.
