Yes. It does perform photosynthesis and fix CO2. It consumes insects largely as a source of nitrogen. Most plants get nitrogen from the soil. But venus fly traps live in places like the bogs where the soils are very poor in nitrogen and other nutrients.

The Venus Flytrap has evolved the ability to thrive in this unique ecological niche by finding an alternate means of getting key nutrients like nitrogen. The insects give them a supplemental nitrogen source.
