Isodontia philadelphica is a thread-waisted wasp found on both coasts of the United States, and hundreds of miles inland - but apparently not through the center of the continent. When the sunlight catches its wings, they have beautiful patches of a deep, iridescent blue or purple.

Unfortunately, even my best picture last year was blurry - I'm looking forward to trying again this summer!

Saw this Sri Lanka Weevil (according to the Seek app) in Florida last week #BlueBugs

We're doing #bluebugs for #bluemonday? Yay! Here's a bluetiful dolichopodid fly! These guys are fun to watch. They're not very shy, and will come back to the same spot again and again. They're little predators who catch smaller flying insects.

I saw some of them for the first time this past summer. So cool! They were only on one particular shrub growing off the sidewalk and it was crawling with them. #BlueMonday #BlueBugs

For today's #BlueBugs hashtag, I offer the NZ Southern Blue, Zizina oxleyi, seen on the campus of #LincolnUniversityNZ.

Students have been counting butterflies in our second year biodiversity class since 2014, using #iNaturalist. They've shown that blues were rare on campus, until one of our big earthquake damaged buildings was demolished and fenced off, making a large wild gravel area for the butterflies to live. That's largely tidied up now.
