Brown Cocoons?

[ArowanaLover1902]

Moth cocoons, I keep bees and there is a moth species (commonly known as wax worm) that makes similar cocoons. It's moths coming to the light of your aquarium at night. Do a little 12:00 stakeout and, if I'm right, then you'll see them flapping around the tank.

I'm fairly sure they're seasonal, so don't worry

Just looked it up and the first picture that popped up was exactly what I have in the tank. Thank Lord I found an answer this has been driving me crazy. I’m assuming they can’t survive in saltwater so that’s why I’m finding them with no hatchings.

I'm glad I was right, may be first time apiculture has helped reefing ever

Oh, yeah! I occasionally find small moths caught in the screen over my tank. Good thinking!

My suggestion would be to buy a potted Sarracenia Purpurea (I used to be into carnivorous plants), this is a small pitcher that will probably get enough light from what comes out of your reef. Give it RO water only. Fairly easy-to-keep plants. Anyways, Mr. Moth flies over to the pretty shimmering light, smells the nectar in the pitcher plant, flies in, is trapped (by the water and downward facing hairs inside the pitcher), digested, and doesn't cause a problem. It's a win-win-win, you don't have to deal with annoying flappers, the plant gets lots of food, and you get an awesome looking plant beside your awesome looking aquarium.

That’s amazing. Were are they laying eggs and maturing to morph at the tank.

Moths aren't picky and the eggs are very small, underside of a table, under an old blanet, etc, or they're outside and coming in. Moths mature very quick and most only last for a few days.

I understand that process. But what are the catapillars feeding on and why are they going to the tank.the moths are attracted to the tank becaus of the ultraviolet lights especially at night not to mention the white lights. To truly unravel this mystery the specimen needs to be id by an entomologist.
