Aruna] Alangium lamarkii flowers during February-April. Buds are opening around the clock and offer pollen and nectar as the reward to their insect visitors. The breeding system incorporates both geitonogamy and xenogamy. Flowers are large, hermaphrodite, essential organs are centrally situated, stigma longer than anthers. Nectar contains glucose, sucrose and fructose. The glucose being dominant. Sugar concentration ranges from 25-29%. Protein and amino acids were present. Pollen-ovule ratio is 27300∶1. Altogether 18 insect species were found foraging at the flowers. Of the 18 species of insect foragers bees (Apis florea, Trigona, Amegilla, Ceratina, Xylocopa latipes, Xylocopa pubescens) and wasps (Delta sp.,Rhynchium) promote both geitonogamy and xenogamy. The bees collected pollen as well as nectar. The wasps while foraging for nectar their dorsal side touches the anthers and causes nototribic pollination. The butterflies visit the flowers for nectar only, but the contact between proboscis and the essential organs is unlikely.
