Edible insects are important dietary component that consumed as food in many developing countries. The edible insects are the rich sources of high quality proteins, fat, vitamins and minerals. Different species of edible insects contribute to variation in nutritional value which depends on the host plant, season and geographic location. The present study was aimed to assess the amount of lipid, cholesterol and triglyceride of Oecophylla smaragdina, Fabricius (the weaver ant) in different developmental stages, castes and in different seasons of the year collected from Upper Assam, North East India. Significant differences (p<0.05) were observed among all the groups and between same caste of queen and worker. The total lipid content in this particular species Oecophylla smaragdina of present study was from10-25% in queen larva, 10-23% in queen pupa and 10-20% in queen adult in different seasons of the year. However, the amount was found to be higher during peak period of availability. Similar trend was observed in case of worker caste but with lower magnitude which ranges from 10-13% in almost all the stages of worker caste. In case of triglyceride, amount was found maximum with 166.81 mg/gm in pupal stage of queen ant in the month of March - April and in pupal stage of worker minimum of 47.75mg/gm in the month of January. Cholesterol content was found relatively higher in pupal stage in both the caste with 15.22 mg/gm in worker pupa and 10.95 mg/gm in queen pupa. Differences in developmental stages, caste and impact of season are quite evident in the study.
