house centipede by myriorama. Photo by myriorama

OK, OK, they weren’t really attacking anyone.

And, strictly speaking, there was only…..oh, say….about….er…….one.

But it was the BIGGEST house centipede  I have ever (evar!) seen. You could feed a family of four off its meaty thighs, I tell ya (should you, you know, desire to eat centipede legs).

It didn’t even run away when I picked up the box it had been hiding under off the kitchen counter (no, I did the running away). Seriously, you could have put a saddle on this fella and ridden him away. He eventually got tired of hearing my whimpering and stalked off (the ground shook!) under the cabinets.

At least, that’s how I imagine birds must view the cecropia moths….”Hey, look at that, Feathers, it’s a HUGE flying dinner! That ought to stuff the kiddies full!”

What?! Can’t I anthropomorphize a bit?

Anyway….

The moths have been emerging steadily with the current count at 3 females and 5 males. They all seem to emerge between 11 a.m. and Noon. By about 6 p.m., their wings are hardened enough to fly off if they choose. Of course, when they first come out of the cocoon, their wings are as fragile as wet tissue paper.

Oh, in case you do decide to have them emerge inside, you will want to put something below the cocoon, as they do empty their gut of all the wastes they have stored up over the winter. Yeah, it’s pretty smelly!

I was surprised that you can’t really tell which cocoon they emerged out of at first glance. Somehow, I pictured more carnage…kind of like Christmas Day with kids ripping open packages.

But, they manage to wriggle out a VERY tiny hole in the end of the cocoon and leave it intact. If you open the empty cocoon up, you can see the shed pupal case (complete with waste in the bottom that was squeezed out as the moth emerged…you are forewarned!).

I still have about 10 left that are sitting in the box. I’m wondering if they just didn’t make it. Here are some photos of the female vs the male antennae:

I think there may have been something amiss with the latest female, as she and 2 males emerged on the same day. I expected the males to flock around here, but they ignored her and flew off. When I looked at her more closely, it appears she may have damaged herself emerging from her cocoon.

Here is a picture of her abdomen and then the close-up of what looks like a rip:

I just love it that these moths look like they are covered in shag carpeting, too!

And look at this beautiful wing pattern:

UPDATE: Turns out the female was O.K. I came back the next day to find her mating, so it looks like everything worked out for her. She did not lay her eggs on the lilac bush, though (whcih is good, because I really need to trim it back this year).

Also, 3 more males & 2 females emerged, leaving only 3 left in the box.

Wheeee!

I did a little happy dance today (trust me, be glad you didn’t see it) when I peered into my box-o-cocoons and discovered this:

moth in box

Success! A cecropia moth! Well, OK, it’s only one but it means a lot to me (and, I suspect, to the moth…).

There she was (I’m pretty sure it was a female, as it looked full of eggs and had smaller antennae), just sitting there slowly pumping her wings.

So beautiful!

I took her outside to show my husband (out in the garage) and as soon as the sun hit her she started to “shiver” in an effort to get things ready for takeoff. Sure enough, in another minute she leapt off the leaf and into the air soaring straight for the trees.

It was really amazing to watch. I hope she gets a chance to mate and lay eggs before becoming someone’s dinner (to a bird, she must look like a big, juicy porterhouse steak…).

sigh.

So, I just finished reading a wonderful book by Bernd Heinrich:

Summer World: A Season of Bounty

(although, not everyone agrees with my view of the book)

It had a nice bit about cecropia moths, although the news was not too encouraging. The bottom line is that very, very, very few cecropia moths ever manage to complete their entire lifecycle.

He mentions that each female cecropia moth lays from 200 to 400 eggs but that most of the larvae that do manage to hatch die. The ratio given in the book for live moths to live larvae was one moth per 100 larvae.

According to Heinrich, parasitic flies and wasps account for the bulk of the larvae deaths. Interestingly, those predators are then often parasitised themselves and then those are parasitised (referred to as a hyper-hyper-parasitoid wasp). Which makes me think of:

“So nat’ralists observe, a flea
Hath smaller fleas that on him prey,
And these have smaller fleas that bite ’em,
And so proceed ad infinitum.”

(As a side note, I was curious about the link to “turtles all the way down” and now want to get a t-shirt with that on it….possibly a job for Endangered Ugly Things?)

Anyway, Heinrich’s book gave a lot of good information on cecropia moths and I would highly advise reading that part if you are planning on rearing these moths. (His moths emerged at the very start of June, but I am still waiting on mine to emerge….stay tuned!)

I hope I get moths and not parasitic wasps/flies…

Things are definately happening inside the cecropia moth cocoons!

Most of them are strapped on to the lilac bush outside (held in place with plastic wire ties around the branches NOT the cocoons) but a few are still left in my inside cage. I took a good look at the outside ones today and they are looking swollen and…well, just different. I think they will emerge any day (night) now.

The ones inside will probably not emerge as soon, but I do hear sounds of movement coming from within them. Wheee! I really hope I can get a nice picture of them before I release them.

In the meantime, please enjoy this short time lapse video giving you an idea of what’s happening inside their silky cocoons:

(And, although its name is not a killing word, it is being killed….)

They’re baaaack!

The Asian Lady Beetles (Harmonia axyridis) have come out of their winter dormancy and are banging around all the windows and lights inside the house. And driving me crazy. (I know, I know, short drive…aha, ha, ha).

The US Ag Department released large numbers of these buggers in order to help control pecan and apple pests. Apparently, they still maintain that they are not a real problem/threat to native lady beetles:

“Multicolored Asian lady beetles have become a problem in some regions of the United States. It is probable that their introduction into new habitats in the United States freed these lady beetles from some natural population checks and balances that occur within their native Asian range. It is likely that these natural controls will catch up to the lady beetles in time and curtail their booming population. Additionally, a period of time may be required for checks and balances of our native lady beetles to adapt to this newcomer.”

I believe this is called the “wishful thinking” doctrine…

Here’s something I didn’t know about these beetles:

“Asian lady beetles are also becoming a concern of the wine industry. Due to their noxious odor, even small numbers of beetles inadvertently processed along with grapes can taint the flavor of wine.”

One article calls this “their special aroma” which is described as a musky basement smell. I can picture the wine tasting now…”Hmm, it’s a saucy little red with hints of moldy cobwebs in dank corners…”

Hodgepodge of Photos

Here are a bunch of photos that I was going to write a blog post around but never found the gumption to actually do so. Enjoy the randomness!
