🏠 The architects of the insect world! Caddisflies can go under the radar due to their cryptic nature, but don't be fooled! These insects are critical to the stability and health of our aquatic systems. Stick around to learn more about these inspiring inventors. 🏠

Hi there! Im doing a deep dive into caddisflies and came across your video, which was immensely helpful! The topic i am researching has nothing to do directly with caddisflies and i know next to nothing about them. But I still have some questions about them and was wondering if you could help?!? It feels like the entire entomology community on youtube has excluded or ignored the caddisfly! 1) Is the sex of the caddisfly determined before the adult phase? Is it possible for a caddisfly to be androgynous at any point in their life cycle? 2) How long is each stage of their life cycle? 3) Are caddisflies able to survive in fresh water and salt water? Or both simultaneously? Can they survive on land? 4) During mating or before mating, how does a caddisfly attract its mate? Is it the male or female that initiates the process? 5) What relation, if any, does the caddisfly have with trees? These questions may seem very random, and I apologize! Any help would be greatly appreciated!

After rewatching, I realized that question 4 was answered in this video. But I would like to add one more general question about this group of insects ! 6) Can two butterflies, moths, caddisflies or any pupae that requires a cocoon to "evolve" share a cocoon? What would happen if this were to occur?

@@funk3795 Hi! Thank you for the support - let me see if I can answer some of these questions! 1) Caddisflies and Lepidoptera sex determination is genetic - so to my knowledge trichoptera sex is set still as larvae. However Lepidoptera can have androgynous individuals (Gynandromorphism) and this can occur in trichoptera too though more rare. 2) Caddisflies spend the bulk of their time as larvae. A couple weeks as an egg, close to a year most of the time as larvae, couple weeks as pupae, couple weeks as adult. This can vary. Most are Univoltine (1 generation per year) but some are polyvoltine (multiple generations a year) 3) Most caddisflies are going to be found in freshwater but some groups can be found in saltwater environments such as the Chathamiidae (tide pools) 5) Even for the aquatic Trichoptera, trees play an important role by shading waterways (temperature regulation), stabilizing soil with their roots, and providing nutrient input into the waterway through leaflitter, fruiting bodies, and the attraction of other organisms. 6) So the cocoon itself is just a silken covering. The pupae is the actual insect. The pupae cannot be shared because this is the exoskeleton of the insect. It sheds its larval exuviae and the pupal case is underneath. If caddisflies shared a cocoon that would just be two pupae under one long extended silk covering - which I guess could cause issues if one hatches earlier and disrupts the silken coating for the other but thats about it. I hope this helps!

@insectspotlightproject thank you so much! A follow up; could question 6 apply to butterflies and/or moths? Or is that cocoon also a part of their pupae exoskeleton? I realize this is all being theorized and appreciate your input. I am trying to find a link between caddisflies and or butterflies/moths with a specific character in a popular movie/series that would have huge implications for its sequel, which have fans deep diving into the lore of the universe. Nerd stuff, but good stuff. Incase you were wondering!

@@funk3795 Haha no worries! So in butterflies the "Chrysalis" is just their pupae - the outer shell being their exoskeleton. Moths will often spin cocoons around their pupae. Both have pupae with an outer exoskeleton - it's just a matter of if the species spins a silken coating (cocoon) around that pupae.

Here's a fun fact about Caddisflys: in addition to being incredibly durable, caddisfly silk adheres whilst completely saturated in water. This made it an excellent subject for study when developing a whole assortment of waterproof adhesive materials.

Not directly Trichoptera, but the first time I saw a Typhonia ciliaris larvae it took me a while to find out what it was, as I was focused on "A land Trichoptera!?"

Haha I would definitely do a double take - I know there are also a select couple species of actual land caddisflies but I haven't personally seen one of those either

Awesome vid! Caddisflies are weirdos lol. My favorite fact about them is that given non rock materials, if theyre still rock like, theyll use them as silk shell materials. With some quick searching you should be able to find a paper and some images of a caddisfly larvae that encased itself in the gold flakes and pieces of lapis they gave it!

Thank you for making this! Bugs are extremely interesting to me, and I’m thinking about going into a field of Entomology. Unfortunately, there aren’t many KZfaq videos on the subject. I just watched your video on Orthoptera (my favorite order) and I loved it! So thank you for teaching people about these critters :)

What do you think of them using the word "bug" to describe more than hemipterans?

@@noeditbookreviews haha I actually still sometimes use bug to describe any creepy crawlies. I think at this point it’s colloquially too established and we roll with it, and let the hemipterans be the TRUE bugs
