Wow us with wasps

Family Chalcididae (chalcid wasps):


Subfamily Haltichellinae / Chalcid wasps are often rather small so it’s a challenge for me to get a good photo when I even notice them in the first place. This one stands out to me due to its thick femurs.

Family Eulophidae:


Eulophidae (좀벌과) larvae on a caterpillar. These wasps inject venom into their lepidopteran host when they lay their eggs to prevent the caterpillar from growing, as shedding its outer cuticle would result in the larvae coming off as well.


Eulophidae (좀벌과) pupa in a cocoon under their caterpillar host. Some species create communal cocoons.

Family Eupelmidae:


Anastatus species / I thought this might be a wingless species at first but it does have wings that are tucked tight against its body. Some species in this family parasitize the eggs of spiders while members of the subfamily Eupilminae have developed an “explosive jump”.

Family Leucospidae:


Leucospis species (밑들이벌속) / Another wasp with pronounced hind femurs. They specialize in parasitizing other wasps and solitary bees. This one was found in a stag beetle nesting habitat set up by the city.

Family Perilampidae:


Perilampus species / Some species in this family are hyperparasites where the female lays eggs on the surface of the host; when the larvae hatch they burrow into the host and seek out the larvae of other parisitic wasps or tachinid flies, which they then attack.

Superfamily Cynipoidea:


Unknown family / I was extremely excited to have this wasp hang out on my hand for a bit, posing for a few photos before flying away. I wish that happened more often with the tiny-sized wasps I encounter.

Family Diplolepididae:


Diplolepis japnoica (참나무혹벌) / Larvae from this genus forms galls on various Rosa species. The peach and yellow colored galls kind of remind me of spiky beach balls – or scoops of strawberry-banana yogurt.

Family Trigonalidae:


Taeniogonalos fasciata (등빨간갈고리벌)

What little is known about the biology of these insects indicates a remarkably improbable life history: in nearly all known species, females lay thousands of minute eggs, “clamping” them to the edges of, or injecting them inside leaves. The egg must then be consumed by a caterpillar. Once inside the caterpillar, the trigonalid egg either hatches and attacks any other parasitoid larvae (including its siblings) in the caterpillar, or it waits until the caterpillar is killed and fed to a vespid larva, which it then attacks. If the caterpillar is neither attacked by another parasitoid nor fed to a vespid, the trigonalid larva fails to develop. (Wikipedia).
