Yes, many tarantulas do make webs, but they don’t usually create the large, intricate, vertical webs that are often associated with spiders in popular culture. Tarantulas typically use their silk in different ways:

1. Burrow Lining: Many ground-dwelling tarantulas will line their burrows with silk, which helps to strengthen the walls and prevent collapse.

2. Molting Mat: Tarantulas will spin a silk mat onto which they will molt, or shed their old exoskeleton.

3. Sperm Web: Male tarantulas will spin a small web, onto which they deposit their sperm before drawing it up into their pedipalps in preparation for mating.

4. Alarm Lines: Some tarantulas lay down a network of silk “trip wires” around their burrow, which alert them to the presence of prey or predators.

5. Egg Sacs: Female tarantulas spin silk sacs to contain and protect their eggs.

However, there are some arboreal tarantulas that do spin more large web structures, usually to construct sheltered spaces in trees or to help them navigate and catch small prey in a tree canopy. These web structures are often more horizontal or funnel-shaped rather than the classic ‘spider web’ shape.

One example of a tarantula that makes a large web structure is the Greenbottle Blue (Chromatopelma cyaneopubescens).
