Ichneumonid Lifecycle and Parasitoid Strategies
<p>The illustrations were published in Hamuli, the newsletter of the International Society of Hymenopterists Vol. 14 Issue ll, Winter 2023. </p> <p>The <strong>first illustration </strong>shows the lifecycle of a parasitoid Darwin wasp: They can reproduce sexually or asexually, lay their egg into/on a host, and complete their full development inside/on this one host. The host is killed and consumed this way.</p> <p>The <strong>second illustration</strong> shows the diversity of the Darwin wasps and their host variation (be aware that the host examples do not represent the only hosts of the displayed wasp species) The illustration displays strategies of endo- and ectoparasitoid wasps, and examples of idiobiont and koinobiont species. Idiobiont wasps immobilize their hosts by paralyzing the larva, which stops further development. Koinobiont wasps do not immobilize the host permanently. After the wasp laid the egg, the host can continue its life while the wasp larva grows.</p> <p>On the <strong>endoparasitoid</strong> side we have <em>Trogus lapidato</em>r (Fabricius, 1787) (upper), that lays its egg inside a caterpillar of a swallowtail (<em>Papilio</em> machaon Linnaeus, 1758). Moths and butterflies are the most common hosts of Darwin wasps. <em>Itoplectis maculator</em> (Fabricius, 1775) (lower) attacks a pupa of an Orchard ermine (<em>Yponomeuta</em> padella (Linnaeus, 1758)).</p> <p>On the <strong>ectoparasitoid</strong> side we have <em>Agriotypus armatus</em> Curtis, 1832 (upper left), attacking a host, which is very difficult to reach: It is under water. The caddisfly larvae are aquatic and build protective cases made out of pebbles and sand. But the female of <em>Agriotypus armatus</em> can walk into the water, covered with air bubbles, and lay an egg on the pupa. The very small and wingless wasp <em>Gelis melanocephalus </em>(Schrank, 1781) (lower left), attacks spider egg sacs from various spider species. However, adult spiders can also become hosts: <em>Zatypota percontatoria</em> (Müller, 1776) (upper right) lays an egg on the abdomen of the spider. The spider can continue its life for a little longer (koinobiont) and can even molt, without the egg being removed. One of the larger Darwin wasps, <em>Rhyssa persuasoria </em>(Linnaeus, 1758) (lower right), with a very long ovipositor, drills into bark to reach a beetle larva. Wasps that have concealed hosts often have teeth or ridges on the ovipositor tip to drill into a substrate to reach the host.</p>
