Introduction:

Spitting spiders, scientifically known as Scytodes spp., are fascinating arachnids that are unique due to their method of capturing prey by spitting venomous silk. These spiders are found in various parts of the world and often coexist with humans in their homes. By learning how to identify these intriguing creatures, you can better understand their ecology and behavior in order to coexist peacefully with them. In this article, we will explore three ways to identify a spitting spider.

1. Physical Appearance:

The most prominent aspect to consider when identifying a spitting spider is its physical appearance. Their bodies are elongated and generally pale yellow or light brown with a pattern that resembles tiny spots or streaks, giving them excellent camouflage against wood and natural surfaces.

– Size: Adult spitting spiders are usually small, measuring between 3-6 millimeters in length.

– Legs: These spiders have long, thin legs that feature a comb-like structure called the calamistrum on three pairs of legs, which helps to spin and manage the spit-silk web.

– Eyes: Unlike most spiders who have eight eyes, spitting spiders feature only six eyes arranged in a semicircle on the front of their cephalothorax (head segment).

2. Hunting Behavior:

Spitting spiders use a unique hunting strategy that sets them apart from other arachnid species. Instead of spinning webs to catch prey, these spiders shoot a mixture of venom and silk from their fangs to immobilize insects at a distance of up to 10 millimeters away.

– Activity: They are most active during late evening hours and night when they hunt for insects such as mosquitoes and flies.

– Movement: Their distinctive walking behavior appears slow and deliberate, often carefully extending one leg at-a-time before attaching their silk.

3. Habitat & Distribution:

Understanding the habitat and distribution of spitting spiders is crucial to identifying them in various environments.

– Habitat: These spiders prefer small crevices, corners, or quiet spots in both man-made structures and natural settings. They often coexist with humans and can be found in homes, barns, under rocks, or tree bark.

– Distribution: Spitting spiders have a cosmopolitan distribution and are found across North and South America, Europe, Africa, Asia, and Australia.

Conclusion:

By examining the physical appearance, hunting behavior, and habitat distribution of spitting spiders, you can effectively identify these fascinating arachnids. Remember that spitting spiders may coexist with humans in homes and other structures but are generally harmless to us. Take the time to appreciate their unique hunting strategies and vital role in controlling insect populations in our ecosystems.
