Yes! I had seen the katydid eggs on a grass stem, and noticed one had a tiny hole in it - I realized what it probably was and kept an eye on it. The next day, the wasps (and one katydid) started hatching.

The katydid was released in the garden. These particular wasps wouldn’t hurt the katydid itself - they lay their eggs inside katydid eggs.

Is this desert flower (sun cup, Camissonia sp.) small? Yes, under 2cm. Is this bee (maybe Lasioglossum sp.?) even smaller? Yes, 5-6mm (zoom in!). To get a blue sky background behind a plant under 15cm. tall, did I have to lie sideways on the ground and get sand in my ear? Also yes.

I don't post a lot of flower photos (unless the flower has a bug in it), but I do make exceptions. Here's a close look at the Red Rock Canyon Monkeyflower (Erythranthe rhodopetra; rhodo=red, petra=rock), a rare endemic found only in, you guessed it, Red Rock Canyon State Park in California. πŸ“·πŸŒΏπŸŒΈ

A phone photo, vertical orientation, of a desert landscape in the slanted light of morning. In the low foreground and into the middle distance are bright yellow, dandelion-like flowers growing intermittently on the sand. The flowers are known as scale bud (Anisocoma acaulis). Larger shrubs, mountains, and a bit of sky are in the distance.

--this one is seasonal and solitary, with no hive. A lone female mates, digs a burrow in the ground (hence "mining" bee), provisions it with pollen, and lays her eggs. Then she seals up the entrance and never sees her offspring. One of my favorite spring species. Mojave Desert, CA, yesterday. 🌼

A macro photo, front three-quarter, elevated view, of a bee inside a pale yellow, multi-petaled flower. The bee is overall dark metallic blue-green, and has a face covered in fuzzy white hairs, bedecked in small round pollen grains.

πŸ™πŸŒΏπŸ“· This wee bee (Andrena olivacea) is a native mining bee. Less than half the size of a honeybee, it looks dull and dark from a distance - but is beautiful up close. It's one of over 1600 species of native bees (which honeybees are not) found in California alone. Like almost all bee species--

A friend (who specializes in native bees & photographing them) and I had this talk yesterday in the California desert. I showed a feral honeybee hive to a couple hiking where we were. They had no idea that honeybees didn’t belong there. My friend said she’s had this convo a billion times.

A photo of a small butterfly perched atop a plant with, curled, holly-like, gray-green leaves and brownish patches. The butterfly is upper left, seen from the side with wings folded. The forewings are orange with white marks, and the hindwings have a row of dark spots along the rear margin, with white and orange below. The body is dark with lots of bluish-white hairs.

In the desert this morning I saw (and heard) a pair of prairie falcons mating, then watched one of the pair (I think the female because of the large size), do a couple of relatively close circles overhead. Luckily, my telephoto lens was safely at home in a cabinet. πŸ“·πŸ¦‰πŸ”­

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.

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 πŸ™πŸŒΏ

During their search for food, most insects head specifically for the flowers that promise the highest reward. Researchers from the #UniKonstanz and the @uni-wuerzburg.de have now studied how bumblebees process information about their food sources. Full story: t1p.de/mndcd

A large-ish mainly dark red beetle in a yellow wildflower covered with pollen 

Beetle from Wikipedia:
Lytta magister, the desert blister beetle or master blister beetle, is a species of blister beetle found in southwestern North America.
Lytta magister

Typically 16 to 33 mm (0.6 to 1.3 in) in length, L. magister has a striking red head, legs and prothorax, with black elytra. They can be found in great numbers in the Mojave and Colorado Deserts in spring, and are often seen in swarms. Females lay eggs in holes in the desert soil. The larvae are insectivorous, mainly attacking bee nests. They consume the immature host along with its provisions, and can often survive on the provisions alone, thus they are not obligatory parasitoids but rather food parasites that are facultatively parasitoid, or simply predatory. Adults feed on flowers and leaves of brittlebush. Though they are not venomous, they can in fact bite.

Wildflower from Wikipedia:
Chylismia brevipes is a species of wildflower native to the American desert southwest known by the common names yellow cups, Mojave suncup, and golden suncup. This is a hairy annual with tall stems often reaching over half a meter in height and surrounded by basal leaves which may be simple or composed of several leaflets. It produces an inflorescence which has one to several blooms in it. The flowers are bright yellow, often with reddish speckling at the base of each petal. The center of the flower has a long pistil and several shorter stamens with large anthers. The fruits are hanging capsules which may be several centimeters long.
