I Also Upgraded My New Centipede. This Centipede Does Not Have A Name Yet. Originally She Was Just In
I also upgraded my new centipede. This centipede does not have a name yet. Originally she was just in one of those plastic food containers that I've kept several bugs in temporarily over the years.


I never planned on keeping her in her in this container for long because its obviously too small and I knew I would be leaving the house to go shopping soon and that's when I got this container

It's much wider and gives her more room to hide and burrow and explore.
This is her new enclosure



I am pretty happy with it

About a week ago, Fel the wolf spider died. I was not surprised because he was an old man, it did feel weird to not have a wolf spider though after his death.


And then last night, I was in my kitchen and saw a large, female, wolf spider and I caught her, I thought I finally had another wolf spider I could take care of since I was quite sad about not having one anymore and female wolf spiders have quite long lifespans.




I immediately noticed that she walked kind of weird, she sort of hobbled around. However, she could still run very fast when she felt threatened, so I wasn't to worried about her.
Unfortunately though, this morning found her dead. My theory is she ate a bug that came into contact with pesticides.
Its very unfortunate that she died though.



I keep thinking he's gonna die or actively dying (of old age) but hes just chilling


Terrible photos but I saw Pebble catch her prey for the first time today
She always catches it when I'm not looking
⋆ ˚。⋆୨୧˚Dytiscidae, Diving Beetles⋆ ˚。⋆୨୧˚
Dytiscid beetles, also known as predaceous diving beetles, are one of the most diverse families of beetles that occupy freshwater habitats. Due to their diversity, they can live anywhere from a stream to a puddle in your backyard. As their name suggests, predaceous diving beetles are known to be voracious predators in their larval stage and, as adults, continue to feed on readily available prey in addition to scavenging. Dytiscid beetle larvae and adults are highly variable in terms of size, head capsule shape, respiration type, and even their tarsal segments. As larvae, they will respire through transcuticular respiration (breathing through the body wall), respiration of atmospheric oxygen via elongated spiracles terminating at the end of the abdomen (Fig. 1), and in one genus, Coptotomus, larvae will have lateral gills on their abdominal segments.

Larvae develop in the water for approximately a few weeks to a few months. Their development time, as with most macroinvertebrates, depends on temperature, food availability, etc. Insects in cooler water will take a longer time to mature, usually growing larger than those that develop quicker in warmer water. Larvae have voracious appetites and will eagerly feed on any small animals available; they have been known to prey on small fish, tadpoles, mollusks, and other aquatic macroinvertebrates. Many adaptations allow them to be such successful hunters such as swimming setae on the tibia (which aids in swimming efficiency) and strong chewing mandibles. When larvae are fully developed, they will exit the water and pupate on the shoreline in a small “nest.” (Fig. 2)

Following pupation, adults will return to the water to feed and reproduce. They can fly for short distances but often are not accurate or efficient at flying due to the adaptations on their legs for swimming. As adults, they use oxygen stores to breathe whilst underwater. The two primary places they hold oxygen are under their plastron (if present) or under their elytra (Fig. 3). The plastron is an area usually on the ventral (bottom) side, and it has specialized hairs and other structures that allow the beetle to trap a bubble of atmospheric air. The air bubble makes direct contact with a spiracle which allows them to breathe. The air bubbles only last so long, and the beetles must resurface occasionally to replenish their air storage. According to some sources, researchers believe that beetles possessing a plastron often experience degeneration of their flight muscles due to the use of the plastron (and the underuse of their wings).

Many male adult diving beetles will have adaptations that aid in mating. The most common being modified forelegs. Beetles with this adaptation have modified tarsal segments on their forelegs; the modified segment has numerous types of setae (hairs) and suction cups (Fig. 4) that allow them to grip the elytra of females during mating. The ability of insects to develop such intricate, specialized structures is what makes them part of the most diverse group of animals on the planet.

The Great Diving Beetle
The Great Diving Beetle, Dytiscus marginalis, is one of the most commonly recognized beetles in Dytiscidae. Despite the name, this species is not the largest in Dytiscidae, but it does grow up to lengths of 1-1.5 inches (30ish mm). Dytiscus marginalis is native to much of Asia and some of Europe, but is now widely distributed across the UK, Wales, continental Europe, and Asia. As larvae, they can reach lengths of up to double their size as adults. Like most beetles, they prefer slow-moving freshwater in ponds, streams, or ephemeral pools. Adults and larvae both have large appetites and will eagerly consume anything large enough to fit into their mandibles. Their diets can range from other insects to fish to snails to small crustaceans (Fig. 5). Adults have beautiful, greenish-brown to black elytra with yellow lines running laterally along the edges of their elytra and thoracic segments. Similar to many insects, the great diving beetle uses moonlight to guide their flight! When ready to lay eggs, the female will deposit her eggs onto the leaf of a submerged plant, and once the eggs hatch, the larvae begin the cycle anew.

Just a little note: I hope this is enjoyable and easy to consume! I apologize it isn't super silly, but hey, maybe that's what you wanted. Also pls don't be mean to me, I am an invertebrate taxonomist so I'm not just pulling things out of my ass <3. okay thx byeeeeeee




My beautiful leg worms. I had to dig them up bc I was moving them to a much larger container (I will post photos later bc I'm buying more things for it)
Thet were in a bin cage but now they are getting moved to a large (20 gallons I think) enclosure:)
There's still some babies I haven't separated out yet but now all the millipedes will have a lot more space so I won't need to worry about overcrowding once I add in the rest of the babies.
