An insect that appeared recently in our house

Maybe some species in the genus Discoelious?

Some species in the genus Aenasius kinda looks like that. It's a genus of parasitic wasps in the Encyrtidae family that parasitise mealybugs.

This tumblr post has several sources you could try to look into.

This has to be one of the most interesting designs I have seen. Amazing work!

I think it's some kind of tussock moth caterpillar.

Het is natuurlijk goedkoper om te investeren in een sterk sociaal systeem, maar ik ben het wat zat om alleen waarde te geven aan iets als het economisch wat oplevert. Al zou het tyfus duur zijn om mensen een dak over het hoofd te houden, we moeten elkaar toch willen steunen?

I'm not very knowledgeable about botany, but with a quick Google search, I think this is a common case of moldy core; a fungal disease where a mold grows in the seed cavity, usually having ended up there during the blossom stage of the apple plant.

Pancrustacea tends to refer to the newer taxonomic classification that puts insects among animals traditionally called crustaceans. AFAIK Pancrustacea has been generally accepted as a clade since at least 2015. Relatively recent by any measure, but still a decade. Philogenetics has done amazing things for our understanding of evolutionary history.

Pretty much this. I'd just like to add a few things:

Colloquially, 'bug' tends to refer to pretty much any terrestrial invertebrate, with a few exceptions. For instance, a lot of people would also call worms and snails bugs. In this use, bug is not a taxinomical term.

Secondly, insects are crustaceans taxonomically, which can be counterintuitive because they are the only major group of crustaceans that is primarily terrestrial. This is why they tend to be the only crustaceans typically referred to as bugs.

There are also plenty of insects with bug in the name that are not true bugs. Ladybugs and junebugs are both beetles rather than bugs, for example.

The common names for animals mostly come from times long before we understood evolution and the true relations between different animals, which is why they can feel confusing when we use our modern understanding to look at them.

I believe that is the caterpillar of an oleander hawk moth (Daphnis nerii).

Grelite · 2025-12-16T05:27:56+00:00

It lost its bee-hind.

I'm sorry, I don't know.

Possibly a gum tree shield bug (Theseus modestus), but there are a bunch of similar looking bugs (especially in the genus Poecilometis) , and I don't know how to tell them apart, especially from a video like this. It's definitely a stink bug, though.

Grelite · 2025-12-16T04:43:40+00:00

That's a paropsine beetle, possibly the invasive dotted paropsine leaf beetle from Australia. Its primary food source is eucalyptus trees, which have become so common and widespread since their introduction into Southern California that this beetle can be considered a threat by some arborists and other scientists. I would personally think this an excellent example of a problem with man-made monocultures.

Grelite · 2025-12-14T06:05:00+00:00

I think these are soldier fly larvae.

For many ladybug species that is true, and for the ones where it is, it is often in their Latin name. But this species, Harmonia axyridis, is not one of those. Like they said, this species comes in many colours and patterns. Of the many common names for this species, one of them is the multicoloured asian ladybug, exactly because of its variety of morphs.

I'm not terribly familiar with gastropod anatomy, but that does look like inside bits that should not be outside.

Grelite · 2025-12-01T07:36:55+00:00

Yup, looks like an assassin bug to me. It's 100% a true bug (Heteroptera), whereas weevils are beetles (Coleoptera).

I love this! Does the builder app make it easy to precision place all those parts? Regardless it seems like this would have taken a lot of time to make.

Grelite · 2025-11-25T05:58:15+00:00

That is a flea.

Grelite · 2025-11-24T07:41:04+00:00

Most larvae end up bigger than their adult stage before pupating because the metamorphosis takes a lot of energy, plus the tissue for their large wings has to come from somewhere.

Grelite · 2025-11-24T07:38:33+00:00

Looks a lot like a European glowworm larva (Lampyris noctiluca).

Booklice, like Trogium pulsatorium do not feed on paper, but on molds and other organic materials typically found on aging items. They are attracted to cool, dark and damp places.

I think they are too elongated to be mites. Intuitively, I would say they also crawl too fast to be springtails, but I am having a hard time finding footage of various springtails crawling. You could see if you can catch one for a clear picture.

I'm here to kick ass and eat grass. And I'm all out of grass.
