Attorney Jose Baez called Timothy Huntington, a forensic expert specializing in entomology, to the stand on Friday. Huntington testified about the insects in the trunk of Anthony's car and at the scene where her daughter was found.
The defense claims the smell from the trunk came from trash. Prosecutors say it came from the girl's body.
Anthony is charged with first-degree murder in the death of her daughter Caylee. She faces a death sentence if convicted. The prosecution contends the girl was suffocated with duct tape. The defense says she drowned in a swimming pool.
Caylee's skeletal remains were found in December 2008.
