hooded owlet moth

Cucullia sp. (Hodges 10180-10214)

I have to say, Andy is incredibly accommodating to my insect-rearing whims.  Twenty years ago, my ex threw a hissy fit after I mentioned I wanted to bring home a couple silk moth caterpillars from class.  I never did.  I should have known right then that it wasn't going to work out.  Ha!  Anyways, Andy got home before I did and even though he was pressed for time to get to an evening meeting, he discovered Charlotte went on her walkabout and he went searching for her around the living room.  Oh my goodness.  He's seen me make these containers enough times that once he found Charlotte tucked under a cotton rug, he knew what to do.  Admittedly, he used an old gym sock instead of nylon (I changed it out before this pic), but he got the gist.  He said she held still for about 3 minutes and then in 30 seconds she was completely under.  That was way quicker than George's 10-15 minutes.  Plus, Andy added a little blue tab to show me exactly where Charlotte had dug herself in.  Good man.  In a few days, I may gently dig up George (on the left) just to document his turd shape with photos, and then return him to the soil.  I'll be setting these containers with papae outside for the winter so they'll develop naturally without the artificial influence of indoor warmth.  I just have to make sure to check on them come spring.  Sometimes I forget I even have them.  Oops.

ps 01/18/16 - Last year I dug up George and inadvertently tossed him over the balcony believing he was a compost chunk.  It wasn't until Charlotte emerged as an adult that I realized what I had done.  George and Charlotte were not smooth, turd-shaped pupae, as I had assumed they'd be.  Charlotte was a fuzzy, pill-shaped object.  As for George, I hope he ended up well.  I have pictures of the adult Charlotte and cannot determine the exact Cucullia sp.

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.

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...
