Great Grape

It’s definitely feeling spring-like these days. There were many more flowers blooming yesterday (including trillium, camas, and shooting star), and I saw three interesting insects on Oregon grape.

Above is an Andrena genus bee with impressive pollen pants. And yes, entomologists really call them that, when bees pack pollen onto the hairs on their back legs. The bees in this genus are also called “mining” bees, because the solitary females make nests in the ground. They’re among the earliest bees to emerge in the spring.

I’ve featured honeysuckle sawflies before, but this was the first one I’ve seen this year, and I think they’re fantastic. Abia americana are the only Abia species of honeysuckle sawfly found in the western U.S. This one was intently feeding on the pollen of the Oregon grape. I love the clubbed antennae, and the coppery abdomen. I hadn’t noticed the yellow lower legs before, but they blend in quite well with the flower.

I wish I had a better photo for this last Oregon grape visitor. At first, I thought it was a piece of forest debris, then I thought it was a tiny moth, which is a decent guess, even at this magnification. But it’s a fly in the Psychodidae family. These “moth flies” are also known as drain flies, and you may have seen them in bathrooms or showers. But there are many more species (and genera) that live in the wild, including this one, which has a nice pattern on its fluffy wings. It moved across the leaf strangely, with its wings hunched up over its head.

I actually saw several (two or three) of these flies on the same clump of Oregon grape. And although I checked a dozen more clumps on my way back to the parking lot, I didn’t see any more moth flies. Maybe it was because the area where they were was more shaded and damp, which Psychodidae prefer, but for whatever reason, that particular location suited them. It’s astounding, and interesting, how micro a micro-habitat can be sometimes.

Enjoy the emerging spring life!

Hello yellow!

You know the Robert Frost poem “Nothing Gold Can Stay“? I sometimes think that the first line (“Nature’s first green is gold”) has yet another meaning, because so many of nature’s first blooms are yellow. Yesterday, I saw two interesting insects on yellow flowers and another insect with yellow legs. (I actually saw a nice-looking black soldier beetle on a daffodil, too, but those photos weren’t sharp enough to publish).

Above are several pairs of rove beetles on a skunk cabbage flower. According to the Oregon Historical Society, skunk cabbage roots are valuable food and medicine for native people (and bears). For the Pelecomalium genus rove beetles, the pollen serves as food, and the “spadex,” or club-like structure in the flower, is their mating ground.

The reason my photo isn’t better is that I didn’t want to step deep into the mucky area where the skunk cabbage was growing. That’s not my footprint to the upper right of the flower, but maybe it was where another animal stepped. Anyway, I feel very lucky that this unique, native plant grows on the Oregon coast.

Dandelions are not special or native, but dandelion pollen can feed some native bees, like this Halictidae sweat bee. Because it was a relatively cool day, the bee sat still for its portrait.

I love sawflies.

I love that until a couple years ago, I didn’t know that this member of the bee-wasp-ant order existed. I love that they look like caterpillars when they’re larvae. I love that the adults can have branched, feathery, or knobbed antennae, and I love the rainbow of colors they can be.

I saw this black sawfly with pale, straw-yellow legs this week. I know it’s in the Tenthredinidae family, but I’m waiting for a more specific determination from BugGuide. (Where “specific” won’t necessarily be to the species, but maybe to the genus … Tenthredinidae is the largest sawfly family, with more than 7,500 species).

I hope you get out to enjoy the first week of spring!

Clicks and likes

The last couple of days have finally felt spring-like, with the sun out and temperatures in the 60s by the afternoon. On a walk around some ponds yesterday, I found this tiny click beetle on the end of a willow catkin. It’s in a genus I’ve seen before, Gambrinus, and my earlier photo looks like it may be the same species.

This is one diminutive beetle. Above, you can see its size on the willow bloom, which is itself small.

On that same walk, I saw this alderfly on a bridge across a stream. These aquatic insects in the Megaloptera order (=”big wing”) live just a tiny part of their lives as adults, spending one to five years in the silt as larvae and adulting for only two weeks or so, in order to reproduce. They never go very far from the water, because they’re not greatly skilled fliers.

Mourning cloak butterflies, on the other hand, spend a relatively long time as adults: up to a year. They are often the first butterflies to emerge in the spring, because they spend the winter as adults, even in very cold climates (it’s the state butterfly of Montana). This one stayed still for quite some time, sunning itself. The deep, red-brown wings probably do a great job as solar panels. I’ll have more information on mourning cloaks in my column for Mount Pisgah Arboretum next week.

Cheers!
