The Alexander von Humboldt Institute records about 3800 species of butterflies for Colombia and in particular 350 for the Amazon which, due to their characteristics, have been positioned as a biocommerce alternative though a limitation for reproduction is the selectivity in their diet (monophagous). Therefore, the phenology study of two nutritious plants Centrosema triquetrum, and Rorippa indica was carried out, for the commercial production of Morpho helenor, Ascia monuste and Leptophobia aripa butterflies in the Paway natural park (Mocoa - Putumayo), to plan production, ensuring quality and quantity. Four phases (germination, emergence, leaf development and flowering-maturity) and two environmental variables (temperature and humidity) were taken into account for the phenology assessment. Food intake was carried out supplying green fodder during larval development cycle of butterflies in groups of five caterpillars per species. Alongside the percentage of dry matter for each species was calculated. It was determined that Rorippa indica presents a phenology cycle of 74 days, Centrosema triquetrum after a year had not bloomed. The humidity presented a highly significant correlation (p ≤ 0.01) for the development of the two vegetal species and temperature (p ≤ 0.01) for C. triquetrum. The Morpho helenor larval cycle was 86 Days, 20 for Ascia monuste and Leptophobia aripa, period in which green forage of the respective nutritional plant was supplied, consuming on average 22.9 grams.
