This is a Giant Ichneumon Wasp. She's laying her eggs. These wasp have one of the most complicated and specialized egg laying processes of any arthropod. This first step is to locate a Pigeon Tremex wasp larvae which are found deep inside tree trunks. Using their antennae to detect a fungus associated with the larvae. Wasp then move on to step two, getting to the larvae to lay their eggs. This is were the wasp's 3 inch long specially designed ovipositors (wire like thing in picture) come in. Ovipositors have an ability to secrete a wood dissolving chemical which they use to mine their way to the Pigeon Tremex larvae so they can lay their eggs on it. After the eggs hatch, they feed on the Pigeon Tremex larvae.
