The nogal cafetero (C. alliodora) is one of the species with more future in the forest activity in Colombia because of the very good quality of the wood and its adaptability to a wide rank of weather and soil conditions. This work studied the biology, habits and distribution of the lacebug D. monotropidia (Hemiptera: Tingidae) in the Antioquia department. This insect is very harmful and closely associate to C. alliodora. The D. monotropidia life cycle took 45.89 days, distributed as follows: eggs 24.10 days; nymphs 21.39 days (2.2, 4.06, 4.18, 4.10 and 6.43 days for the first, second, third, fourth and fifth nimphal instars respectively). The females incrust the eggs in a single group (45.49 eggs average) in the main nervadura by the under surface of the leaves. The females take care of the eggs until they hatch.
