hooded owlet moth caterpillar
Cucullia sp. (Hodges 10180-10214)

That's George above.  I introduced him in a post from 2 days ago.  I mentioned he was mobile. Very mobile.  I provided him and his cohort Charlotte rather tall flax-leaved horseweed (Erigeron bonariensis) stalks (the same kind I brought them home on), because I was hoping to avoid the daily chore of obtaining smaller, quick-to-wilt clippings from down the street.  This is all to say, I did not have them in a container.  I simply stuck the trimmed stalks in a heavy-bottomed vase with water and a cotton topper to prevent accidental drowning.  Yep, the larvae were loose and fancy free at home, in my home.

And, George made a run for it today.  Twice.  Argh!  At first, I thought he was just searching for fresher food.  He somehow managed to get off the table and onto the floor, but that was about as far as he got.  The second time he disappeared, with a plethora of just-the-right-sized leaves to munch on, it dawned on me he must be looking for a cozy place to pupate.  It took me an hour of carefully searching every nook and cranny (man, I have some serious dust bunnies behind the furniture) until I finally found him nestled in a silty groove of our sliding glass door rail.  Phew!  I worried that if he had found a way to get into my houseplant containers, he'd be lost for good.  Plus, I had vivid images of settling in on the couch to discover something smooshy stuck to my bottom.  Yuck.  Good thing I found George.

If I hadn't dug up the large yellow underwing pupa in my compost a few years back, I don't think I would have known to simply provide a little loose dirt.  I quickly cleaned out a couple containers (another for Charlotte) and dumped in a couple inches of slightly moist compost.  I inserted a crawling stick for later and then set George down on top of the dirt.  After a few minutes of playing dead from the traumatic handling, he started wiggling himself in short spurts and then pauses, head first into the soil.  Shown above was about halfway through.  Within 10-15 minutes, he had dug himself completely under.  I was kinda surprised at how quick he was, because I had never witnessed how this happens before.

While the colors are a bit washed out in my photo, George had already started changing colors, loosing the bright yellow center dorsal stripe and gaining a reddish-brown tailend that looks a lot like a sclerotized head.  Doesn't he look a bit like a millipede here?  Very cool.

humpback whale ~ 09/15/14 ~ Pacific Grove Shoreline Park

humpback whale

Megaptera novaeangliae

We've had an extraordinary showing of humpback whales in the Monterey Bay recently, and today was the best so far!  The Monterey Bay Whale Watch states 70 humpbacks were spotted in the a.m., with 79 midday, and 84 (a heck of a lot!) on a bonus evening tour (as is shown here with that whale watching boat that got way too close).  Most of the road (Oceanview to Sunset) along PG's Shoreline Park was unusually crowded with landlubbers and several seriously ginormous camera lenses that likely cost more than my car, all pointing towards the water.  It was a great show.  Without binoculars, we could easily spot 4 very active areas (lots of blows) that didn't seem to move much.  Usually, the activity drifts or disappears after a few minutes.  This apparently lasted for hours.  Very cool.

Kinda crazy, and just goes to show how ignorant I can be sometimes, but humpback whales are still listed as federally endangered.  Ya.  No kidding.  That surprised me.  They were delisted from IUCN's Vulnerable status to Least Concern in 2008.

Here are extra humpback whale links: SIMoN Special Status Species, Marine Species Identification Portal, Marine Bio, Society for Marine Mammalogy, and Wild Whales (out of British Columbia).

I should mention that there were also 200 long-beaked common dolphins (Delphinus capensis), with 1500 seen 2 days ago, September 13, 2014.  Amazing.

hooded owlet moth caterpillar prolegs (+ aphids)
Cucullia sp.

Yesterday, we walked down Oceanview above the Rec Trail with hopes to spot and cheer on my cousin Bob while he ran the last leg of the PG Triathlon.  We found Bob in the race... and a couple brightly-colored caterpillars on the same tall stalk of roadside weed.

Cats were fresh on my mind, because I had just received an e-mail from Gordon Pratt explaining his techniques for raising tiny blue butterflies and essentially encouraging me to do the same.  Eh, I make for a rather lazy lepidopterist and generally only raise whatever I can easily find (read: large enough to spot from 5 ft. away!) and if I'm in the mood.  It's been a while since I've reared anything, the last ones being Genista broom moths as a pest management favor for J.  I've had moderate luck with larger leps in our relatively cool coastal climate (e.g., Lophocampa success and unidentified woollybear failure), but I haven't reared anything as small as blues (except for the accidental poop-shooting orange tortrix relative).  So, while I figure out the logistics for raising tiny cats (and whether I have the patience for such endeavors), I'm dusting off my rearing containers for a bit of practice with yet another larger caterpillar.

À la Gary Larson, here are the newest additions to our family (note: he/she designations are purely random)...

Charlotte

Those are her gorgeous black prolegs in the first picture above.  She was voracious and slightly smaller than her companion.

George

Slightly larger, less hungry, and definitely more mobile.  Go, George, go!  I quickly stuffed a cotton ball into the vase, so roaming George wouldn't drown.

I didn't measure either one (remember, lazy), but they were maybe 2 inches long.  They seemed to prefer medium-sized leaves off stems that could support their hefty stature.  Within a day, the single stalk I found them on was stripped bare, except for side supporting stems and wispy flower-bud tips, whereupon I ran down the street and collected 2 more stalks for food.  Oy!  I inadvertently brought home lots of other insects from the clippings (aphids, ants, an inchworm, and a syrphid fly larva).

Until I see their adult form, I can't really say which Cucullia sp. these are.  My ID search started with googling images of "zebra striped caterpillar".  No kidding.  Yep, super-scientific.  Not!  But, it works.  That took me to the zebra caterpillar (Melanchra picta), which gave me Hodges number 10293 and a decent starting point.  Btw, Moth Photographer's Group has a excellent series of caterpillar plates for North America.

Cucullia speyeri (Hodges 10190) looks like a superficial match, but Robert W. Poole indicates C. speyeri is not found anywhere near here.  I think he's the same fellow who wrote a Noctuid catalog, so he would know (but I'm not positive).  There are certainly enough look-alikes, here (various), here (thin yellow stripe on side w/ white prolegs and white bindi), here (Hodges 10191), and here (wide yellow stripe on side w/ facial freckles and white bindi, not laetifica), so it's hard to say if this one from San Diego on CalPhotos is correct.  The Cucullia adults are not much easier to tell apart.

 flax-leaved horseweed / asthmaweed

Erigeron bonariensis (aka Conyza bonariensis)

Asteraceae

It's because of the reported native host plant for C. speyeri, horseweed (Erigeron canadensis, aka Conyza canadensis), that I was able to track down the ID of this non-native < 4 ft. tall relative.  I checked the few flowers in bloom, and they definitely look like bonariensis, not canadensis, to me.  I'll try to take pictures of this plant in situ, as the one I have here was otherwise stripped of its leaves and didn't look like it normally would.  More to come...

acmon blue on naked buckwheat ~ 09/10/14 ~ Podere di Farfalla

mating Icaricia acmon (aka Plebejus acmon) on Eriogonum nudum var. auriculatum
Polygonaceae

I mentioned in a previous mating acmon post on seacliff buckwheat from mid-July about how host plant associations cannot be assumed.  I'm trying to do a better job at documenting the butterfly, the plant, and the activity.  Here I found them on another type of buckwheat (one that was not evident to me back in July).  I was able to get a series of mating photos that made for a surprisingly graphic gif.  Unfortunately, after succumbing to a fit of giggles, I decided other people may not appreciate my crass animal p0rn humor (or it might get stolen and put on a site I would be embarrassed to show my grandmother, if you know what I mean).  And so, it's not included on Nature ID.  However, it was eye-opening to see how butterfly sexy parts actually fit together.  I never took such a close look before.

Icaricia acmon laying egg on Eriogonum nudum var. auriculatum

This is the true money shot for me.  Laying an egg on an identified host plant.  Although, as I witnessed this spring, females sometimes get their host plants mixed up.  No kidding.  It's apparently how insects regularly adapt to using introduced plants.  It's evolution in action.  At the time, I was encouraged to find the egg of my unusual sighting.  Ha!  I tried, I really did.  It's very much like looking for a needle in a haystack.  Miniaturized.  What's not always obvious from photos is exactly how small all of this is.  I seriously doubt I'll be able to get a clear picture of something as tiny as an acmon egg out in the wild, on a cliff, in bright sun, and the ever-present wind.  With my relatively recent need for reading glasses, I couldn't even see what the egg here looked like after the female did her quick drop off.  I'm starting to view television nature shows in an entirely different light now and not in a good way.  Instead of oohing and awing over nature, I'm wondering how the heck they managed to film whatever it is that they did.  Seriously.  Eh, I like my easy crappy photos.  So, on to the plant...

naked buckwheat / ear-shaped wild buckwheat

Eriogonum nudum var. auriculatum

Polygonaceae

While I already suspected which buckwheat this was, I used the plant list for Podere di Farfalla to narrow down the possibilities of buckwheats, from 256 spp./var. found in all of CA to just 6, plus 4 more from nearby Garland Ranch.  I looked at all the possibilities, and more, just to make sure it wasn't something I hadn't heard of before.

and solidly fuzzy below

(my descriptive words, nothing to do with plant keys)

The official CNPS list for Garland Ranch shows another of the 14 var. of naked buckwheat (geez, there's a lot), sometimes called hairy flowered buckwheat or Fremont's wild buckwheat (E. nudum var. pubiflorum).  I took a close look at the few available photos online, and I think the leaves here look more like auriculatum than pubiflorum.  Leaf shape more determinate over level of fuzz on top?  It's a close call, and I could be wrong.  If anyone knows better, please tell me!
