Got a few nice #macro photos with the #fire #ants today, and managed to get a shot of the tiny chompers on this male. If you want to support my work with fire ants, don't forget to leave a like on my #scicomm video! Contest ends Saturday! youtu.be/DXypfsxjl0Q?...

How often do you run into your school's mascot? This southern #yellowjacket #wasp queen was buzzing around my backyard yesterday, probably looking for a place to overwinter. Hope I don't meet her daughters in the spring

I made a video for @galacticpolymath.com describing #MySciJourney in the world of #ants as part of their science communication challenge. Give it a quick look and remember to leave a like! #scicomm #outreach

Throwback to when I met my first trapjaw #ant (Odontomachus brunneus) in South Alabama. She gave me a little kiss, but it would be weeks later until I got my first sting. Ponerine venom feels really different from myrmecine, don't you think?

I'm planning to post more cool #ant pictures from my short time in #Colombia but I can't resist sharing this spiny #Trachymyrmex in the meantime. What big eyes she has! 👀

It's national #Pollinator week in the US! Here are a couple photos of native #bees, a paper #wasp, and the best #mosquito I've ever met! Where would we be without them 💚

Finally, we have males. These look more similar to wasps than ants, and bear small wing spots on the outer margins, near the abdomen

This is all in service to the family. She has a mother and plenty of sisters and juveniles to feed. The queens are almost indistinguishable, bearing wing scars on the larger thorax and an abdomen ready for oviposition. Can you spot her?

Without hope, this worker #termite fights back against it's predator, biting her leg. Ultimately, the needle ant beats the crap out of it. Literally.

I had a photoshoot with the #NeedleAnts today, #brachyponera chinensis. I couldn't decide what to post, so here's a thread, starting with predation on a favorite meal here in Atlanta, a #Reticulitermes worker

A new neighbor moved in this spring. Polistes exclamans is so vibrant

Walking the tightrope is a bit less impressive when you have 6 legs tipped with claws and gripping pads. But hey, you're in the show!

Meeting up at the (sugar) watering hole
Getting some more practice with my #macro lens and some #solenopsis invicta fire #ants . You can tell not only the variation in size, but also age! The smaller, pale ants below (called callows) will turn darker as they age.

Got a simple clip on #macro lens for my phone, and I think it's working alright. A #camponotus worker #ant with pretty well developed ocelli sat still just long enough for a half decent photo

Happy #DarwinDay! Today, we celebrate biology, diversity, and the environment. I'm always so excited to learn more about the world we share with such amazing creatures.
Don't be afraid to flip over rocks or ask questions, you might just learn something by accident!🐜

So far my only paper, so I guess it's my "best known" 😅
Florida Harvester #Ants ( #Pogonomyrmex badius) vary their insect foraging across the year, but they always like seeds. Also, #Solenopsis invicta fire ants are mean but not deadly for FHAs. Message me if you want to learn more!

Ever feel like your work follows you home? These #Solenopsis invicta fire #ants were building a nest on my sidewalk this afternoon

They don't call em sweat #bees for nothing! They're always welcome to me or the peppers in my garden. And they make great #macrophotography practice

Currently missing all the #ants in hibernation around my yard. Here's a favorite genus of mine, #Odontomachus, from the Gulf Coast on my wedding day last summer. She wasn't invited, but she was welcome anyway
