A study investigated to explore the distribution of insect gall in two different areas at Kozhikode district, Kerala (Vatakara and Koyilandi). Galled and ungalled plants were collected from these two study areas. These galls bearing plant parts were dissected and observed under the stereomicroscope. Followed by observation sorting and phenolic test was done up to family level and the possible galls were photographed. So the present study revealed that the galled leaf show higher phenolic content when compared to its ungalled leaf.
