Scale larva?

Scale larva?
Alameda County, California, USA
November 14, 2009
Size: ~1/4 in., 6 mm
Stationary on an outside wall (painted siding) for a few days now. I think this is a larval stage of a soft scale. The blue is painter's tape, added to reduce the amount of white so the creature would photograph better. Even so, I couldn't get detail in the shot.

Do you have a reason
to doubt that these are tortricid eggs?

 
No
It's only that there's an Unidentified Eggs page for moths and none for tortricids. These eggs will never get an ID. I haven't seen anything emerge.

 
Eggs that have been identified to family
have been identified to some extent, and we place them at family level. We make separate pages for them if it is justified--I recently made a page for unidentified noctuid eggs because they were scattered over many pages--but with Tortricidae if you select the "caterpillars only" view, there are so few images there that the eggs and larvae together only take up one page. If/when BugGuide 2.0 happens, it should be possible to select "egg" (or pupa, nest, etc.) for a given taxon and just display those. It's always best to place images at the most specific level to which they have been identified.

 
I see
It seemed to me that "egg" was a more specific designation than "tortricid" because there are so many species of tortricids, shown as adults or caterpillars. Images are often moved in steps to their final spot--I thought I was taking the placement one step further. So these go back to Tortricidae, huh?

 
Yes
That is the place where they will be most useful, since it is the place someone would look to find out what tortricid eggs look like. The general section for unidentified lepidopteran eggs is a place I might visit from time to time to see if I can ID any of them to family, but I'm not sure who else might look there or for what reason.

Looks like
a tortricid egg mass to me. Baby scale insects look like this:

Non-mobile stages of scale insects are only found on plants.

 
Wow
The tortricids I'm most familiar with are (probable) Pyramidobela angelarum, and they lay eggs on the host plant. They have great success at infesting buddleia. Why would a moth deposit eggs on wooden siding with no plants within easy walking distance for tiny caterpillars? To get in line for the Darwin Award? This is the second such yellow formation on this part of the house. The other one dried up; at least, that's what it looked like.

 
Question
Near a light that might be lit at night?

 
No
It's near the back door, which isn't lit. The wall faces southwest and gets direct sun several hours a day. Both yellow constructions were about four feet from the ground.
