The proximate analysis of two edible insects in Ijebu division (South Western Nigeria) was analyzed. This was carried out to clarify the nutritional elements evident in the two edible species. The samples were collected through water trap and by handpicking respectively with a view of adopting the method of the Association of Official Analytical Chemists for the proximate analysis. Proximate analysis of these two revealed that Rhynchophorus phoenicis (larva) and Macrotermes bellicosus (winged reproductive) were very rich source of protein (63.14%, 47.08%) respectively. Fat level (8.19%, 22.45%) varied between both species both with very low carbohydrate (1.65%, 1.82%). They were rich sources of crude fibre (21.99%, 15.82%) and ash (37.34%, 31.83%). Both insects are sources of vitamin A, B1, B2, B3, B5, B7, B9 and B12, C, D, E and K. The minerals study in R. phoenicis (larva) and M. bellicosus (winged reproductive) revealed that Manganese (2244.90mg/kg, 75.85mg/kg), Magnesium (2844.90mg/kg, 603.00mg/kg), Potassium (5032.50mg/kg, 5063.00mg/kg), Iron (269.55mg/kg, 353.30mg/kg) were present with low Calcium level (1.96mg/kg, 1.54mg/kg). In view of this, the two edible insect species are rich sources of protein, vitamins and minerals. Hence, itís recommendation as a candidate for baby formula to be used as an addictive for the production of baby food or convalescing adult.
