Help us help you: Guidelines for submitting pictures for identification

135 Upvotes

Hello r/Entomology! With this community being used often for insect/arachnid/arthropod identification, I wanted to throw in some guidelines for pictures that will facilitate identification. These aren't rules, so if you don't adhere to these guidelines, you won't be banned or anything like that...it will just make it tougher for other Redditors to give you a correct ID. A lot of you already provide a lot of information with your posts (which is great!), but if you're one of the others that isn't sure what information is important, here you go.

INFORMATION TO INCLUDE WITH YOUR PHOTO

  • Habitat: Such as forest, yard, etc.
  • Time of day: Morning, day, evening, or night will suffice.
  • Geographical Area: State or county is fine. Or, if you're not comfortable with being that specific, you can be general, such as Eastern US.
  • Behavior: What was the bug doing when you found it?

Note about how to take your photo: Macro mode is your friend. On most cameras, it's represented by a flower icon. Turn that on before taking a photo of a bug close up, and you're going to get a drastically better picture. With larger insects it's not as big of a deal, but with the small insects it's a must.

If you follow these guidelines, you'll make it easier for everyone else to help you identify whatever is in your photo. If you feel like I've left anything important out of this post, let me know in the comments.

According to Wikipedia, "Larvae are known to wiggle vigorously at periodic intervals in synchrony. How they synchronize these movements especially when distributed over a wide area has not been established." BUGS ARE SO COOL AND MYSTERIOUS!!!

Hello!!

My wife and I were surprised by a loud cicada on our 10th floor balcony (top floor). There's no plants or anything up here that bugs would be interested in.

The cicada kinda spooked my wife. He spent some time trying (and failing) to climb the metal legs of our chairs/table. We gave him a piece of wood to climb on.

I suggested we could probably just toss him off the balcony. My wife said no way he'd survive. I said his terminal velocity would be low enough his exoskeleton would take the force no prob, plus he could fly a bit. She said they're not very good flyers. We left him on his piece of wood.

Mostly out of curiosity, do you guys think he would've survived the 10 floor drop or no?

Tyia!!

(Pic 3 - he tried to climb the leg (attempt 4), slipped, flipped himself around, and landed upside down on his face. He sat there like that for a couple minutes. So so cute)

Pet/Insect Keeping filmed my ant jumping on a roach at 10x slow motion — and the jump is STILL a blur

reddit compression eats macro detail. full res versions are on my channel: youtube.com/@VenatorsHunt

these are harpegnathos venator, one of the few ants that hunt by sight instead of following scent trails. she watched the roach, crept up, and closed the distance in a single jump. i slowed it down ten times and you still barely catch it.

they also kept a functional wasp sting — the venom paralyzes rather than kills, so the prey stays fresh for the larvae. and the larvae feed on it themselves, which almost no other ants do.

this is my own colony, kept at home in Kyiv. filmed on a phone

happy to answer anything about them

ID Request Is this normal for asian lady beetles???? It has irregular lines and splotches of black in its patterns, rather than the typical symmetrical spots! (More pictures in comments)

I've never seen this before and couldnt find anything similar on Google! At first I thought it was just the rain droplets on its back making the patterns look warped, but no those are the actual patterns it has! Sorry I couldn't keep the camera still with how much I had to zoom in. I'll put some still pictures in the comments (would've put the pics in the post itself but then i wouldn't have been able to include the video). Is this rare??? Regardless, its absolutely beautiful!!!

My first time watching monarch caterpillars pupate and turn to butterflies. Is this guy dead? There was another that made very little change and then broke out of the chrysalis overnight. This one is turning brownish.

Insect Appreciation Kariguu, Master Weaver. A character inspired by my 20 year old Salmon Pink BE

60 Upvotes

Ok before anyone says it, I know spiders are not insects. But I’m less sure… does the study of entomology include arachnids? Like, do professional entomologists include spiders in their studies or is there a line drawn?

Anyways, I wanted to share Kariguu, the Master Weaver with this sub! She’s a major character in the anthropomorphic fantasy novel I’m working on. The scene here is when she makes her introduction. The artwork is by u/nickthagreek, the talented fountain ink illustrator of the project.

Kariguu is based on the actual 20 year old salmon pink birdeater living in my home office that I’ve kept since she was a wee spiderling. Her near infinitely patient real life behavior was the basis for the strange, ancient, almost eldritch-like being that is Kariguu.

Hope fans of insects can dig a fun fantastical depiction of an arachnid!

ID Request Potential Chagas?

Enable HLS to view with audio, or disable this notification

Sorry for the poor quality video but could this potentially be a chagas nymph? I’ve been dealing with the weirdest chronic illness over the past few years and I was randomly talking to my best friend today and he told me about how he got bit by a chagas bug and how it could lead to a pretty serious disease.

My hunt for figuring out a diagnosis has been a long, exhausting journey and I would truly just crack up if my best friend randomly solved my diagnoses from a story he decided to tell me about by chance! Ive struggled with literally every single symptom of acute Chagas and recently within the past month have developed some very concerning symptoms in my heart that sound very similar to the rare symptoms of later stage chronic Chagas’ disease.

I’m sure it’s probably still an absolute longshot but wanted to at least identify this bug just in case. Thank you in advance for any help you all can provide!

Hi All! I woke up this morning and found this on the trim inside our house. The eggs were not wet, but we used a wet paper towel to try to get them off. There’s a film of gray fuzz underneath it. We live in Pennsylvania.

What do you think left it behind? Thanks in advance!

im having a hard time getting a good photo but theyre more orangey than red and they have more angular backs than smooth and round like ladybugs. also- there had been some small larvae/caterpillars that were black with orange stripes on them before I left, I'm assuming that these came from them
