  1. Nests were collected from a 20 × 20 m grassland plot and a forested patch at the microclimatic field station of the Universidad del Valle, Cali, Colombia. Mean number of cocoons attacked by Macrodinychus sellnicki in parasitized nests is reported. Only nests containing cocoons were considered for this comparison.
