Invasive scale insects cost U.S. agriculture at least $4–8 billion each year, yet true losses remain poorly tracked. For scale insects and beyond, an accounting of these losses is a major blind spot that complicates pest control, policy decisions, and efforts to protect food production.

my modest collection of flies with WIDE heads 🙇 a hammer-headed Richardia (Ecuador), a stalk-eyed Chaetodiopsis (Mozambique), a pointy-eyed Ophthalmoptera (Colombia), and an antlered Richardia (Colombia) why though? male-male competition? sexual selection? chime-in if you know!

Day 19 of my 2025 Favorites: Schizomida mom and her cluster of baby clones! I've had many generations of these tiny arachnids from 2 females (they're parthenogenic) collected in a public park near Miami a few years ago, and happened to spot this one with her babies one evening. Delightful lump 🥹
Light brown and red leggy arachnid in a bit of wet wood, her booty in the air like a spire, with her ghostly white babies facing downward clustered around it almost like an unopened flower

let me share a little story about a remarkable wasp that I encountered yesterday in our local deserts I stumbled across her, and scrambled to get a few crappy photos .... but then realized that she had a burrow, perhaps a better photo op was possible ?? here she is at her burrow entrance.

Reposting because the final version finally came out and there are way more people on the site now. To you it might just be a genome note, to me it's the first fully Mongue lab paper (feat. @erincpow.bsky.social and @kkbugtime.bsky.social )! A #newPI milestone! academic.oup.com/g3journal/ar...

Florida's newest invasive mealybug currently prefers roadside weeds but may pose a threat to solanaceous crops (e.g., tomatoes, peppers). This species was only recently described from Japan where it is likely also introduced. New open access paper: www.degruyter.com/document/doi...

This moth was attracted my head torch and decided to rest on the net-casting spider I was photographing! Deinopis spinosa (Deinopidae) with Arta olivalis (Pyralidae) in north central Florida. #SpiderSunday

New paper out! We describe three new species of giant mealybugs from Mexico & Guatemala. You think spiders have a lot of eyes until you see male Puto mealybugs. Some species have 18 eyes! The drawing is Puto philo, pictured alive is a Puto decorosus from California. www.mapress.com/zt/article/v...

More of the sentient gherkins 🥒 from yesterday, this time on their preferred host, croton (Codiaeum variegatum). They blend in beautifully. Phalacrococcus howertoni first showed up in Florida in 2008 and was undescribed at the time. It probably originates from the Caribbean or South America.

Cockerell (1898) described this whitefly species as with "...ribbon-like rays of glassy secretion, not much shorter than itself. These rays are of a bright lemon yellow". Now we have some live photos to show it! Lemon yellow indeed. Aleuroplatus vinsonioides (Aleyrodidae)

"Trash bug" lacewing larvae feed on mealybugs and then use the mealybugs' wax for camouflage. But mealybugs can fight back with "reflex bleeding," oozing fluid that gums up the lacewing's mouth. Entomologist @erincpow.bsky.social captures one-of-a-kind photos and video of this behavior.

Happy New Year! Here's a quick collection of just a few of my favorites from 2023. An assortment of scale insects, spiders, various arthropods from Florida, and arthropods from my summer trip to Europe which spanned Georgia (Republic of), Switzerland, France, England, and Scotland.

My top inverts of the year! Pecan giant scales (Neosteingelia texana). Active for only a couple weeks, emerging from the bark briefly to mate. These were out on hickory in late October in north FL. This year was my first time seeing them, I was slightly obsessed. Name a more sexually dimorphic duo!

Finally trying out BlueSky! Ever wonder how a 'trash bug' gets its trash? My new paper (tinyurl.com/42pw4r5m), with videos, documents dorsal packet construction by a lacewing larva & defensive reflex bleeding by mealybugs. See the videos here: www.youtube.com/watch?v=As95... #InverteFest
