Malnutrition is one of the serious problems encountered by Indonesia. This research aimed to identify local knowledge and practice on entomophagy in Datengan Village, Kediri, East Java, Indonesia. The entomophagy data were collected by the qualitative approach. The edible insects in this study were honey bees (i.e., Apis mellifera, A. cerana, and A. dorsata) and flying termites (i.e., Macrotermes gilvus and Odontotermes javanicus). All aspects of the local and scientific name, halal status, harvest period, local value, and how to collect, prepare, cook and serve have been described in this article. There are two arguments about consuming termites: haram or halal (considered a type of grasshopper). On the other hand, consuming bees (A. mellifera, A. cerana, and A. dorsata) is haram to eat adult bees. Meanwhile, consuming bees that are still in the form of larvae is halal, but it is to be haram if they are eaten separately with honey or hive. Both termites and bees were not cultivated and processed into several types of foods such as fried, bothok, and rempeyek. There were five challenges in entomophagy such as disgust, allergy, inferior, halal status, and complicated processing methods.
