Distinguishing morphological features of Order: narrow waist formed between the first two segments of the abdomen which is fused to thorax, two pairs of wings with fore-wings being little larger than hind-wings.longer Antenna than head but not highly elongated (longer than thorax and head combined),chewing mouthparts with well developed chewing mandibles,some groups have one pair of head appendages( the second maxillae) are fused into the labium.

Sub-order: Apocrita

Order:Hymenoptera

genus and species ?

Geographical Distribution: Hymenoptera are common world wide.

Life cycle:Complete metamorphosis (holometabolus) has egg,larva,pupa and adult. Some larvae are grub-like,lacking legs.

Sexual dimorphism: Females have a special ovipositor for inserting eggs into h.Males usually develop from unfertilized eggs.The young develop through complete metamorphosis — that is, they have a worm-like larval stage and an inactive pupal stage before they mature.

What it eats: typically herbivorous, feeding on leaves or pine needles. Stinging wasps are predators, and will provision their larvae with immobilised prey.Some young ones feed on pollen and adults take nectar.

Habitat: Nearly all wasps are terrestrial; only a few specialized parasitic groups are aquatic.

Ecological importance: Generally wasps are parasites or parasitoids as larvae. Adult stage: important in preserving ecological balance and maintaining biological diversity in terrestrial ecosystem. a few species can effectively transport pollen and therefore contribute for the pollination of several plant species,Parasitism and predation prevent numerous insects from becoming crop and forest pests.

Economic/agricultural/human health importance: Pollination which helps to fertilize plants.
