habitat ~ 08/21/10 ~ Fort Ord - BLM Creekside

August 21, 2010

During this hike, it felt like I physically moved from spring, to summer, to fall at Fort Ord in one day.

The first photo above has a great egret (Ardea alba), which is more closely related to the great blue heron (Ardea herodias) than it is to the snowy egret (Egretta thula). I still get the common names mixed up, since there's also a white form of the great blue heron, called the great white heron. Mainly what I want to show in the first pic is how much water is left in one of the vernal pools this late in the year after the winter and spring rains. It's been so drippy wet foggy here on the coast the past month that I'm not surprised there's still standing water. We've been wondering at what point does the heavy fog officially become precipitation.

The second pic is classic CA summer grassland, dry and yellow almost as far as the eye can see. The heat and dryness are the main reasons why I don't hike out there much this time of year.

The last pic is of CA buckeyes loosing their leaves for the year. This is about as 'fall' as it gets around here. There's still "Spanish moss" on the oaks, a local term that is not the real Spanish moss. Really, what we have is not moss at all, but a lichen called Ramalina menziesii. Interestingly enough, within 10 feet of this picture, there was one lone lupine shoot making a bloom. I'm sorry to not have taken its photo to show.

ps 02/16/11 - For a great post on our local lichen, check out Curbstone Valley Farm. And, recently while we were watching a PBS show on snub-nosed monkeys, I found it interesting that they eat lichen. Their big lips and snowy habitat reminded me of cartoon depictions of the abominable snowman, aka yeti.


common jimson weed
Datura stramonium
Solanaceae

I really wanted this to be our native western jimson weed (D. wrightii), but alas this is the non-native. The flowers look similar in photos, although I suspect the western jimson weed flowers can get quite large. D. wrightii appears to have smoother leaf margins, whereas D. stramonium leaves are more toothed. I double-checked Fort Ord's plant list to confirm this ID. The seed pods are impressive. It seems the origins of this plant are unclear.

seed bug ~ 08/18/10 ~ at home

Mediterranean seed bug
Xanthochilus saturnius

I thought this was a handsome bug. I'm making a quick guess that this is some kind of seed bug, a true bug. My husband asked how I knew it was a true bug. I look for the 'X' pattern the wings make as they cross each other, flat over the abdomen. Most adult true bugs have half membrane and half leathery outer wings, which emphasizes the 'X.'

I'm an old school entomologist, long out of practice, and I still think of Hemiptera (true bugs) and Homoptera (hoppers, cicadas, and aphids) as being in separate orders. Now, they've been combined in the order Hemiptera and separated out to the suborders Heteroptera and Homoptera. Confused, yet? Yeah, me, too. I kind of liked the classification the way it was. I'm not sure what the current description is to describe the now larger encompassing order. Maybe the piercing sucking mouth parts along with gradual metamorphosis?

I posted this now to show I don't just do plants, especially orchids, on this blog. If you know the ID to species, I'd greatly appreciate it. Otherwise I'll look into it later, but right now I need to get my butt over to a bocce tournament... CiĆ o!

ps 08/23/10 - I posted this yesterday in a rush. I've edited and added the common and scientific names below the photo above with embedded links to UCI and BugGuide, respectively. I can't believe this is my first true bug posting. The Mediterranean seed bug hails from Italy... it's kind of coincidental since I was off to meet the Sons of Italy yesterday.

ps 04/22/12 - Once again, I've been "put in my place" by a popular blogging entomologist who has insisted on correcting me for years on other people's blog postings for topics I consider are matters of opinion. There are now sometimes considered 5 suborders within Hemiptera: of course Heteroptera, then there's also Fulgoromorpha and Cicadomorpha (both are sometimes considered as infraorders, suborders, or superfamilies of Auchenorrhyncha), Sternorrhyncha, and Coleorrhyncha (sometimes treated as an infraorder of Prosorrhyncha). No one seems to agree. I'm sure there will be more changes. I feel sorry for those newbie entomology students out there.

Michael's piperia ~ 08/11/10 ~ Toro Park


I'm feeling very repetitive these days, but I want to have a blog record of timing and location of orchids for next year. Now that Andy has been interested in looking for orchids, he seems to be seeing them on all his trail runs. It's a good thing.

ps 08/21/10 - Michael's piperia has a stout stem and seems to be found right along the trail sides in disturbed areas. Today, a friend and I saw the tail end of blooms at Fort Ord - Creekside, which is located just across Hwy 68 from Toro County Park. She didn't quite believe me it was an orchid until I pointed out the 3 remaining blooms on the tip.
