Cormorants will surprise you if you look closely. What a GORGEOUS bird

A macro photo of a slender, tiny wasp atop a batch of katydid eggs. The eggs, which look like brown lima beans, are tiled along a brown grass stem. Four have roundish holes chewed through their sides, where parasitoid wasps (like the one perched on top of them) chewed their way out. The wasp is metallic-copper colored with a yellow abdomen band and large eyes.

A macro photo of a group of katydid eggs, which look like brown lima beans, tiled along a brown grass stem against a pale green background. In the upper right, a tiny wasp's face is peeking out of an escape hole it is chewing from the inside of a katydid egg it has parasitized. A second egg, lower left, has a hole in it where a wasp has already hatched and flown off.

A macro photo of a tiny, green, newly-hatched katydid nymph perched atop a fingertip, against a green and blue-green background. The fingertip and katydid are lower right, and one of the katydid's extremely long antennae stretches all the way up to the upper left corner of the frame.

From a few years ago: katydid eggs mostly parasitized by tiny wasps. When a katydid hatches, the egg opens like a clam shell; but as you can see (pic 2), if there's a parasitoid wasp inside, they chew their way out. Btw, the baby katydid on my fingertip hatched from the same egg clutch. #BugSky 🐙🌿

For some reason the juvenile Attinella concolor which roam the white sands and wiregrass of Florida savannah are bright orange (adult males are a gorgeous silver). The ones from other habitats are a more drab brown.

A very strange looking mayfly nymph, backlit against white with some aquatic vegetation. It has a pronounced hemispherical snout, and it mottles yellow and black.

I gotta get some of the weird chironomids imaged...But everything aquatic is pretty fascinating!

Anyone got pointers on taking pics of little things that are under 1mm, underwater, and still moving?

I have the magnification for it (SLR lens and microscope setting on my phone), it's just the water surface reflection that gives me trouble every time

I will try! If I get anything going this summer I will be sure to document what I can.

Thanks! I might have some time this summer to continue experimenting, depending on my field schedule. Would really like to do more of this messing around!

Also I got some fancy antireflective optical glass from Edmund OPtics, and tried siliconing it to a container. That was really lovely in combatting contrast loss and things, but I need to experiment in making smaller versions.

Cheapskate Tuesday 17: Micro Aquaria! A couple weeks ago, I explained my desire to shoot some aquatic invertebrates in small aquaria, using a store-bought betta tank. This larger enclosure will serve well for the larger animals I might…

I have made mini aquaria by sandwiching two microscope slides together at various widths: ibycter.com/cheapskate-t...

I collected this spider while playing with my kids at the local playground. I’m glad I did because it looks like it may be a new record for BC/Canada!

Une fois de plus, la science citoyenne contribue à la découverte d'une nouvelle espèce sur iNaturalist Community science leads to yet another scientific discovery! A new species of wasp-mimicking flower fly, Monoceromyia ndidiae, has been identified in the Dominican Republic through iNaturalist.   From observation to publication: A new species of wasp-mimicking flower fly Publié le 30 Jui 2025, 16 h 32 min par seastarya   image : Observation by @franklinhowley   ------ traduction   « L'aventure a commencé lorsque @franklinhowley, membre de la communauté, a partagé des photos sur iNaturalist qui ont attiré l'attention du naturaliste Aaron Schusteff (@arbonius), qui a reconnu qu'il s'agissait d'une espèce non décrite. Cette observation initiale a donné lieu à une collaboration qui a finalement abouti à la description formelle de l'espèce. Jiri Hodecek (@jiri_hodecek), entomologiste légiste chez SHIFT à Lausanne, en Suisse, a collecté le spécimen holotype. Ximo Mengual (@ximo_mengual), chef de la section Diptera au musée Koenig -LIB de Bonn (Allemagne), explique comment cela s'est déroulé : « L'observation dont Aaron parlait est celle partagée par @franklinhowley, mais il a pu trouver d'autres observations de la même espèce. Ce n'est que lorsque nous avons su que nous avions un spécimen physique que nous avons pu confirmer l'espèce. »   Traduit avec DeepL.com (version gratuite)   A New Species of the Wasp Mimic Flower Fly Genus Monoceromyia Shannon, 1922 (Diptera: Syrphidae) from the Dominican Republic, 16.07.2025 https://bioone.org/journals/proceedings-of-the-entomological-society-of-washington/volume-127/issue-1/0013-8797.127.1.70/A-New-Species-of-the-Wasp-Mimic-Flower-Fly-Genus/10.4289/0013-8797.127.1.70.short   Les photographies du nouveau taxon ont d'abord été partagées sur iNaturalist, où il est resté sans nom pendant des années jusqu'à ce qu'un spécimen soit collecté à l'aide d'un piège lumineux dans le parc national Valle Nuevo en République dominicaine.   via Monoceromyia ndidiae de Jardin Botanico, Santo Domingo, Dominican Republic le 22 Jan 2023 à 11:55 par Franklin Howley-Dumit Serulle · iNaturalist https://www.inaturalist.org/observations/147287717

An image of the book cover: a ringed planet in greens and blues with organic-looking growths seeing to sprout from the rings, and a spaceship in the foreground.

The eagerly awaited follow-up to @aptshadow.bsky.social's bestselling Children of Time series, Children of Strife follows our MC as she tries to determine what has happened to her crewmates who left the ship to explore an interstellar ark.
