Lattice Orbweaver Spider - (Araneus thaddeus)

Authored By Staff Writer | Last Updated: 1/22/2014

The web of the Lattice Orb Weaver Spider is a neat round of silky ladders, radiating from the center.

The characteristics of the web are useful in identifying the Lattice Orb Weaver Spider. It also has six defined black spots on its abdomen. Each spot has a very pale ring around it. The yellow and orange coloring can vary in depth, but all of them create similar looking webs.

They can be found in meadows, tall grasses and bushes as well as fields and pastures. Their small orb-shaped webs are usually built low to the ground, not at elevations that most people would see before walking through.

Females lay eggs in autumn. The fertilized eggs are wrapped in an egg sac spun out of her silk. Spiderlings may hatch during part of the winter or they may overwinter completely, depending on the weather. All adults die in winter.
