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.

Pest Control Mosquitoes kill ~700,000 people a year — and they're breeding in a bottle cap of water in your yard.

111 Upvotes

Mosquitoes kill ~700,000 people a year — and they’re breeding in a bottle cap of water in your yard.

I'm a Board Certified Entomologist, and every summer I watch people fog their entire yard with pesticides while completely ignoring the actual problem: standing water.

A few things most homeowners get wrong about mosquitoes:

1. You don't have a "yard" problem, you have a water problem. Aedes mosquitoes (the ones that spread dengue, Zika, and yellow fever) can complete their entire larval cycle in something as small as a bottle cap. Plant saucers, clogged gutters, tarps, kids' toys, that bucket behind the shed — that's where your population is coming from.

2. Larvae are your early warning system. Before you ever get bitten, the larvae are visible — little wriggling "tumblers" hanging at the water's surface. Dump the water and you've eliminated hundreds of future adults without spraying anything.

3. Spraying is the last resort, not the first. Broad-spectrum fogging kills pollinators, beneficial predators, and often barely dents the mosquito population if breeding sites remain. Source reduction first, then targeted larvicides (Bti dunks are cheap and won't harm pets, birds, or bees), then adulticides only if truly needed. This is just standard IPM — Integrated Pest Management.

4. It takes about 7-10 days from egg to biting adult in warm weather. Which means a weekly "tip and toss" walk around your property is genuinely one of the most effective mosquito control measures that exists. Costs you nothing.

I love how these little buggers live underground for years and only emerge during the late summer months.

Mecynorhina torquata ugandensis "blue"

Here we have an l3 larva (that still have quite a lot left to grow) of Mecynorhina torquata ugandensis, blue line. This is a famous flower beetle from central Africa widely kept in captivity for its ease of care, huge color variability and relatively fast larval time; it's also impressively sized, second only among flower beetles to (not even all) species of the genus Goliathus, the Goliath beetles. This specimen in particular is a male... in the second pic he kinda looks like the brainbug from Starship Troopers.

While on my morning walk, found this beautiful one who had passed away. Felt wrong to leave it on the sidewalk so I moved it under a tree in the grass. Would love to know if it was male or female, and how to tell 😊

Located in Houston Tx area. Found them eating my jumping spider’s meal worms. The container is well sealed and they weren’t there a few days ago. Looks like they are eating the worms. Can I also feed them to my spider?

This is a nice, not cheap brand of home products and I do not understand why they did not put dragonflies or butterflies instead of them...

Edit: I took this two days ago but if you want the set, here it is https://www.finlayson.fi/products/suukko-pussilakanasetti
it is not AI . The print is called Kiss (Suukko). "The Suukko pattern, designed by Jenna Kunnas, challenges the formula of traditional floral patterns. There are many surprising and intriguing elements among the flowers and kisses."

I can’t seem to ID this wasp down to species but I also can’t quite tell what it’s doing. It’s ovipositing into the flower head of a purple coneflower, but why? The only wasp I could find that maybe made galls in them looks nothing like it. Perhaps it was ovipositing into something inside the head like the parasitic mites or midges that cause galls? I’m not quite sure but hopefully someone can help with this
