Did y'all know caddisfly larvae could swim? I sure didn't.

Fossil Caddisfly (Trichoptera) In Baltic Amber
hello! enjoy a wide smattering of bugs
big and small i love them all
also snails are bugs because I say so
also also if you want to id them for fun for yourself you can they're basically all from ny but I typically use inaturalist rather than. waiting specifically for your inbox to open lol
also also also sorry if this is too many they just bring me joy
I also love them all! I won't list all the IDs since there are so many, but I will say that the spitting spider and habrosyne moth are my favorite :))
I was so happy to see one of my favorite examples of visual mimicry in Costa Rica! take a look at this Petrophila moth and a Nectopsyche caddisfly. notice anything familiar about the pattern they seem to share?
it’s the front view of a jumping spider! black round eyes in rows, and stripes for legs with gaps between them. the resemblance, especially seeing the mimics at actual size in person, is striking. both moth and caddisfly have a reflective white patch of scales around the eyes, making them seem reflective and alert.
jumpers are active visual predators, a threat to small insects but also to one another, and have good facial recognition skills for members of their taxonomic family who might be rivals or predators. it’s thought that a jumping spider, viewing a mimic, might be scared off or even consider it a rival and start a territorial display, giving the mimic time to flee.
many Petrophila and their relatives in the subfamily Acentropinae have the jumping spider patterns, and I saw a few species with varying degrees of spideriness. there’s a surprising amount of other arthropods that mimic jumpers, too, from planthoppers to cockroaches and even other jumping spiders with false eyes.

Caddisflies - Trichoptera
@transpotato5 thank you for reminding me of this species ! ! And, @jettfisch, you might like these, considering you like bone collector caterpillars.
A/N: It is a bit of a short and chaotic post, this one, but yeah, I hope you will enjoy it :DD
Introduction
Caddisflies, or Trichoptera, are a group of insects with aquatic larvae and terrestrial adults.
Integripalpian larvae of caddisflies construct a portable casing to protect themselves as they move around looking for food, while annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them.
In this post, I will mostly highlight the suborder Integripalpia.
Examples of Case Building Caddisflies
Below you can see two members of the genus Neophylax, these are caddisflies who specifically belong to the family Uenoidae, who are more commonly called stonecase caddisflies.
On the left: Uenoid caddisfly larva, Neophylax mitchelli. On the right: Uenoid caddisfly larva, Neophylax consimilis.
However, I think they (caddisflies larvae) might be better known for aiding in creating the art of Hupert Duprat, a French artist. The casings made by these larvae are just gorgeous, at least in my opinion.
Duprat’s aquatic caddis fly larvae, with cases incorporating gold, pearls, and turquoise, among other materials.
Examples of Caseless Caddisflies
As gorgeous as case-building caddisfly larvae are, the caseless ones are rather gorgeous too. Take, for example, Rhyacophila fuscula, or green sedge caddisfly larvae, which have a gorgeous bright green colour.
