Stephanidae – An encounter with a rare parasitoid wasp
This odd-looking creature is commonly known as the ‘crown wasp’ due to a ring of tubercles on its head but is known by scientists as a stephanid.
Stephanus is greek for a crown, thus, Stephanidae.
Its strange body structure can be hard to make sense of, so let me try and explain: The orange/brown part to the left is the head, to the right of that the thorax with the wings attached, and the part sticking up into the air is the abdomen, making up the three major segments of an insect.
But what is that long needle-like structure on the right?
That is the ovipositor, the technical term for an insect’s egg-laying device.
The wasp uses this ovipositor to stab beetle larvae and lay eggs in them, which it does by using its legs to sense vibrations from beetle larvae living inside the rotten wood it has landed upon. After a few days, the deposited egg hatches, and a wasp larva develops inside the beetle larva, eventually killing it and emerging as an adult, which then flies off to stab a beetle larva elsewhere in the rainforest and start the process all over again…
Some parasitoid wasps actually use a form of echolocation (just like a bat would) to locate their prey. They have modified antennae that tap the rotten wood and specialized ears on their legs that can hear the tap’s echo off of a larva and locate it that way.
This particular rotting tree had several of these wasps on it, so clearly there were some stab-worthy beetle larvae within.
Note: this wasp is a parasitoid because it kills the beetle larva host, opposed to a parasite that just feeds on it but lets it live.

The lodge is located in the middle of the forest accessible only by boat. The experience was very unique and exciting. Service is great, and the fun part are the nature activities and tours the hotel offers for free. We had an amazing tour guide that had a lot of knowledge and was fun to spend time with. The rooms are totally open to the forest which is really cool the struggle is the there is no privacy at all in between the rooms, also food was pretty basic. All together a very unique experience.

This hotel is the perfect blend of comfort and hospitality, with the natural experience. The hotel is reached by a hours boat ride from Puerto Maldonado, expertly organized and accomplished. Most staff are members of the local Esa Ejja community. The food is good and plentiful. Hot water is always available and lovely bedding features mosquito nets. There is of course no air conditioning (one side wall is open in rach room) and the electricity is off for a few hours at night affecting overhead fans, so I was glad to have brought a small battery powered fan for sleeping. But the best of the experience is the wildlife. Our expert guide Oscar Mishaja introduced us to nearly 100 bird species, along with caimans, river otters, poison dart frogs and capybara. A trip of a lifetime. Read all

We had a surreal experience at Refugio Amazonas. From the well organized transportation to the warm welcome, hospitality and the experience of living in nature - we loved it all. Huge shout out to our guide Boris who went out of his way to ensure we had a good experience and got to watch all kinds of wild life. The meals and cocktails were delicious. And even though this place is smack in the middle of the jungle there was super fast WiFi available. We made unforgettable memories. Read all

El mejor hotel para visitar la Amazonia peruana. Hotel eco turístico metido en medio de la selva, equipado para visitar y vivir la selva, su flora y fauna, en todas sus facetas. Todo incluido, con guías preparados y amables, resultó una experiencia increíble para mi familia. Dentro de las opciones no se debe perder el Canopy de 45 metros de altura para observar y escuchar la selva, así como el lago de las tres Chimbadas, lugar único para ver caimanes, nutrias gigantes, monos y aves exóticas. Recomiendo mínimo dos noches!!! Read all
