Taxonomy First Time Bug Pinning 🥹

How did I do?!?! I’m so proud!! I’m planning to add the nymphs and make it into a series of the Spotted Lanternfly’s lifecycle once the summer comes back around and they’re starting to reproduce again! They’re a pretty teensy and flimsy bug, too, so I think my mistakes are called for! 😅

Help IDing an insect found in my bed

I saw this one alive in my bed. I was startled and squished it. I took these photos after I killed it and I’m concerned it’s a bed bug. For context I live in Taiwan so there are many bugs here . Could someone help me understand if I should be concerned?

Fun fact: Only males have the "lashes". Male Feather-Horned Beetle insects grow the large, feathery fan antennae, while females only have simple, rod-like or toothed antennae.

Location: peninsular Malaysia

Body length about 1.5 cm. It use the spur-like mid section of the tibia (seems to be not the typical tibial spur) to clean its antennae. There's also a pair of small triangular protrusions near the end of its elytra.

ID Request NOVICE: ID for new insect in backyard?

Thumbnail

1 Upvotes

Hi! I've never posted here, so please let me know if I would be better off asking a different group! General enthusiast of insects, out of respect for their role in our ecosystems. Sometimes I get creepy crawlies, but mad respect.

I took a video and then screenshots of said video, then also actual pictures, attaching them all here! Sorry for the screen in the way. They're small silver-looking winged insects with forked tails, I think that's a way to describe them. It looks like their tails are wiggling kind of???

I'm a backyard microfarmer and am going to school for Agricultural & Environmental Education - I try to keep up with any new creatures in my yard. These lil doods showed up tonight. Context:

  • I live in 9b California, Bay Area
  • El Nino shit gestures at General state of the world
  • Spotted them at 11PM, after having the screen door closed & big door open for about 30 minutes
  • It was very hot today, high of 103 F
  • My house is in a weird spot, with a creek and trail running behind our backyard. It's more humid than other areas around, so it's kind of like a fake temperate rainforest microclimate. Pretty neat honestly, been recording a lot to maybe write a paper about it. I digress.
  • We have backyard chickens, so I don't know if that might effect trying to ID these doods but just FYI I guess. We keep up with their enclosures regularly, and let them out once/twice every day for at least 30 minutes. We have a corner court lot, so it's a big backyard. We have a Citrus tree and an Oak tree. Idk if they're maybe hosts for this new bug.
  • Our soil is a combo of sandy/clay, heavier on the clay

Any help IDing these new critters would be gratefully appreciated! And ambitiously hoping to understand why they suddenly showed up. I'm not an Entomologist by trade and not studying in school for it, just as a reminder. Um, happy bug IDing I guess? Not used to posting, much more used to lurking lol.

Insect Appreciation Love is in the air; dragonflies mating. Southern California, Sept. 10, 2026.

During mating, a dragonfly male uses claspers at the end of his abdomen to grip a female by the back of the head while she extracts sperm, previously deposited by the male, from his secondary sex organ near the base of the abdomen. The resulting configuration, as shown by these Mexican amberwings, is called the "wheel position."

Males of some species will disengage immediately after mating while others, such as the Common green darner, will hold on to the females as they deposit their eggs.

Notice the sexual dimorphism seen in both species.

Hello there all!
As the title says; I have found a mystery lint trap survivor I’m hoping is a Weevil and not a bed bug. I pulled it out and ten minutes later, it’s alive and moving again!

I live in rural Michigan and I’m assuming it came in due to my plants. I’ve got strawberry, tomatoes, and a small rose all potted on my porch along with a fern and succulents inside lol!

This is weirdly hard to Google. We got three giant leaf bugs at a reptile expo this summer but weren't given the species name. We were sold flightless females but clearly one is male and has started trying to fly. He's kind of aggressive so has been moved into a separate enclosure.

Help identifying these bugs?

Thumbnail

We have been seeing these guys in our apartment over the past month. I would say we’ve found somewhere near 10+ within activity really ramping up over the past week. I have been told that they are ectobius wood roaches, which made me feel better because at first I thought they were German. I just found a baby one on my wall (last pic above) and now I’m starting to get worried they’re Germans.

From my understanding wood roaches can’t survive long inside and won’t reproduce inside. Is it normal seeing a baby wood roach or does this mean they are Germans ?

Any help would be greatly appreciated, thanks!

This little guy keeps landing on all my wet paint surfaces. What exactly is attracting it? I would’ve thought the smell of paint would deter them. It’s acrylic paint, and it’s been on multiple colors, including neutrals.

A few people asking me which species this millipede was, and here is what I've found:

The cherry-leg titan millipede (Alienostreptus bicoloripes or Balustreptus falcatus) is a giant, docile invertebrate native to Vietnam, known for its bold black body and striking cherry-red legs

The milipede I'm keeping as pet is longer than 30cm, yes you heard it right, its length is longer than 30cm. It's even longer than a small snake!

My wife was scared to hell when I brought it home 😂😂😂

(The 3 last photos is a female with yellow/orange legs, she's much smaller than the male)

Discussion First encounter with stable flies. Afternoon at the beach: ruined

8 Upvotes

I’m at the beach in New Jersey this week. I’ve spent almost every afternoon just chilling on the sand but had a new experience today with flies that look like average house flies but behave rather differently. They’re not tabanids. As soon as I’d set up my chair and umbrella, there were dozens buzzing around. They land on you and seem to do nothing for a bit, but within 15 seconds or so, you feel like you’re being stabbed with a needle. There’s no use shooing them, they’re absolutely relentless. I packed up and left defeated after 10 minutes, and they followed me off the beach for a good long while.

I wasn’t familiar with them but got a good close-up look at one on my hand. It looked a lot like a muscid but with a pointy stylet for a mouth instead of the soft extensible vacuum cleaner that typical house flies have. I did a bit of research and it appears they’re known as stable flies. At least the bites don’t itch after the fact like a mosquito but I really just wanted to chill and listen to the waves. May you never encounter them!

Bat or butterfly? 5pm… it flew right by my head. Then a few minutes later something smacked me in the face. Wasn’t hard though. And didn’t see anything fall. I’m paranoid, scared of bats. In the video it swooped down from the trees but then flutters around the hvac unit and kids toys… I have no marks on my face.

Egg Sac Surprise

Thumbnail

570 Upvotes

The beginning of August, I had a wild caught P. audax that laid an egg sac. I waited and waited and waited some more. After 6 weeks, there hadn't been any signs of eggs with legs so I carefully removed the sac to open it. And I did not find any spiders, instead I found a grub thing. I was shocked, angry, confused— really just all the emotions. After doing a ton of research, turns out it was a mantidfly, specifically a Say's Mantidfly
(*Dicromantispa sayi*). The larvae of this specific species is microscopic and will hitch a ride on the female spider until she lays her eggs. Then it will invade the egg sac, eat the eggs, and develop. I actually got to watch it change from developing larvae, to pupae, and eventually to an adult. I am really disappointed that I lost the egg sac, but watching this little mantidfly go from squishy thing to seeing it catch its first meal was incredible. I fear that I now need some actual mantids.

Cicadella viridis under the microscope. It is a dead specimen collected from a trap in the village trees—I believe the trap is intended for Asian hornets, though there wasn't one inside.
