Distinguishing morphological features of Order: Hind wings smaller than front wings, linked together by small hooks (hamuli).In flight,both wings operate in unison;Chewing mouthparts - except in bees where maxillae and labium form a proboscis for collecting nectar.They have large compound eyes, and typically three ocelli.

Sub-order: Apocrita

Order:Hymenoptera

genus and species ?

Geographical Distribution:worldwide

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: Herbivory is common among the primitive Hymenoptera.Most other Hymenoptera are predatory or parasitic. The large hunting wasps are agile predators that catch and paralyze insects (or spiders) as food for their offspring.parasitoid wasps larvae feed internally on the living tissues of other arthropods (or their eggs).

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.

Economic/agricultural/human health importance: bees pollinate many of our crops,and they also produce goods such as wax and honey. Parasitic wasps are often the most successful way to control pest insects without excessive use of insecticides.
