#Evania appendigaster

[arthropodenjoyer]

this little guy showed up on my house today

it is a blue eyed ensign wasp (Evania appendigaster)

these wasps parasite cockroach eggs, so having them around is pretty neat

[shibs]

You know the extra where Laios compares Kabru to a parasitic wasp? I keep seeing people being utterly confused about it, or calling Laios dumb over this comment, but the explanation is so simple: there is actually a blue-eyed parasitic wasp! “You even look kind of similar” -> talking about their big blue eyes!

Also, Laios is not being stupid or literal about it (he knows Kabru is not the child of a wasp, the guy understands basic biology), he just took that ‘what IF you were the kid of a monster?’ thought experiment and ran with it– why? Just for the fun of it, look at that big smile :D

(The extra comic + full pics of the wasps under the keep reading)

Here's the comic for those unfamiliar with the wasp comment:

The name of this wasp species is Evania appendigaster and while I oversaturated the pic in the post to make my point, its eyes are pretty blue indeed!

Weird Wasp....Tuesday?

I was getting kind of down in the dumps about not having any ideas for comics for a while, but I just had to find an excuse to draw an Evaniid today. The other two came into the picture afterward. Sometimes, it can be quite a challenge to come up with an idea or scenario that incorporates some kind of joke or pun related to certain insects, especially wasps.

I'm glad this one worked out. I suppose it would have made more sense to draw an ootheca in the picture, although I am curious about wether the ootheca "appears" externally after mating? I've seen photos of female Periplaneta americana without oothecae, either that, or I'm blind, lol. I welcome any advice or corrections!

The original accompanied caption:

When cockroaches are on the menu... Ampulex compressa and Evania appendigaster are both cockroach parasitoids. A. compressa is known for "zombifying" cockroaches, by stinging them in the brain and then dragging them into the wasp's burrow by the antennae. An egg is then laid on the host. E. appendigaster, aka Ensign wasps, parasitizes roach oothecae by laying eggs into the cockroach egg cases. They also distinctively have vivid blue eyes.

This will be an interesting match! Who will win!? 🤔 😆

(Also, if rock-paper-scissors doesn't require hyphens, I can easily remove them).

Everyone loves the large black ensign wasp (Evania appendigaster), but I'm in love with Hyptia floridana, a species which is like a 1/16th scale model of the large one 🥹

Evania appendigaster better known as the blue-eyed ensign wasp, is a species of wasp in the family Evaniidae, which was originally native to southern asia but has spread throughout much of the worlds tropics, subtropics, and temperate regions and can be now found on every continent barring Antarctica. With adults reaching upwards of .6 inches (15mm) in total length, it is one of the larger ensign wasps and can be distinguished from other species by the wide separation of the first and second sections of the coxa, the segment of the leg that attaches to the body. It sports large wings, and its body is black in color with contrasting blue eyes. The abdominal petiole, the constricted stalk that holds the posterior section of the abdomen, or gaster, is attached high on the body. The gaster is laterally compressed and oval to nearly triangular in shape, held in a flaglike fashion and resembling an ensign, hence the name. This wasp reproduces by laying eggs into egg cases, or oothecae, of cockroaches. The mother wasp sneaks into a cockroach nest then upon finding the eggs, drills a hole into them with her ovipositor and lays a single one of her eggs inside each cockroach egg capsule. The wasp eggs then hatch are there larvae feed upon the cockroach larvae, growing and developing through 5 instars emerging from the now empty egg capsule as an adult. As adults blue-eyed ensign wasps feed primarily upon plants such as parsley and fennel and may live upwards of 3 weeks.

#2119 - Fam. Evaniidae - Hatchet Wasp

AKA ensign wasps, nightshade wasps, hatchet wasps, or cockroach egg parasitoid wasps. The family name is derived from the genus Evania, itself from the Greek euanios, meaning 'taking trouble easily'. I have no idea why that's appropriate.

All sufficiently well-studied Evaniids are parasitoids of cockroach eggcases, but since only 16 of the known 400 species are sufficiently well-studied, that doesn't mean much. Evania appendigaster and Prosevania fuscipes are both now found worldwide, because they're parasites of worldwide pest cockroaches.

Before 1939 the Evaniidae was a wastebin taxon for any oddly-shaped parasitic wasp, and the infra-order 'Parasitica' wasn't much better. Happily, the Evaniidae, Gasteruptiidae, and Aulacidae have a pretty good fossil record going back to the Middle Jurassic, although they're much less common since the late Cretaceous when the Ichneumonidae and Braconidae took over.

I keep seeing this little guy in my bathroom, to me it seems like a hymenopteran or dipteran but i honestly cant tell further. Could you id? (Spotted in southwest florida)

looks like Evania appendigaster, the blue-eyed ensign wasp. they parasitize cockroach egg cases, so often found in Florida where there is a surplus of those

Cockroach Egg Wasp (Evania appendigaster)

[onenicebugperday]

@clownmilkz​ submitted: i saw this bug on my wall and i immediately thought weta but i know thats not right. its got a thin waist that goes into the abdomen and it was wiggling its abdomen in a way that reminded me of a wasp, before it jumped the speed of light to unknown location. i slowly walked away wiping my clothes. i live in australia!

It’s definitely a wasp! Specifically an ensign wasp, although I can’t tell which species from this photo. Ensign wasps are known for their comically small abdomen. Here’s a better look at one:

Your friend could have been this species, since it’s fairly cosmopolitan!

hot girl side table except i am not hot or a girl and this probably isnt even a side table: coffee that doesn’t seem to finish. a book. another book. this cool wasp i trapped in a jar because it’s the first time im seeing it and i suspect that it’s an Evania appendigaster. glasses that are literally broken (the lens fell out of the frame). nintendo switch :)
