Understanding Spiders: A Basic Overview

Before delving into specific types of spiders, it’s essential to understand what defines a spider.

Spiders are a type of arthropod, a classification of animals characterized by three main traits:

1. Invertebrates: Spiders lack a spine.
2. Exoskeleton: Their bodies are protected by a hard exoskeleton made of chitin.
3. Segmented Bodies and Jointed Limbs: Spiders have two main body segments: the cephalothorax (the “head” portion, housing the eyes and mouth) and the abdomen (the “back” portion, which contains vital organs and silk-producing spinnerets).

Spiders fall under the subclass Arachnida within the arthropod family. Arachnids are distinguished by:

• Eight Limbs: Unlike insects, which have six.
• Chelicerae: Specialized pincer-like mouthparts for feeding.

Other arachnids include ticks, mites, and scorpions. Spiders are unique among arachnids due to their venom-injecting fangs and silk-producing spinnerets. These adaptations have enabled spiders to thrive globally, excluding Antarctica, for over 200 million years, making them the seventh most diverse order of organisms on Earth.

Spiders in Missouri

In Missouri, only two spider species pose a threat to humans:

• Brown Recluse: Known for its potentially serious bite.
• Black Widow: Recognizable by its shiny black body and red hourglass marking.

Other spiders in Missouri are either non-venomous or have bites that result in minor irritation rather than serious harm. Although they may look intimidating, they generally pose no significant risk.

Preventing Spider Infestations

• Seal Entry Points: Ensure doors, windows, and foundation cracks are properly sealed.
• Remove Clutter: Spiders like hiding in piles of clothes or unused items.
• Regular Cleaning: Dust and vacuum regularly to eliminate spider webs and egg sacs.
