Larvae in cells with capping that is not intact?

[Kevin M. Pfeiffer]

Here (#001812 2011-08-18) are numerous empty cells where adults have recently emerged and the cells have not yet been cleaned up. But at the same time there are numerous cells where the capping is not intact or appears damaged. In some cases one can see presumably still healthy(?) brood (e.g. 2nd row from bottom, left side).

What to do with cappings that appear damaged or not intact?

What to do when cappings are not intact but one can see otherwise healthy-looking "old larvae" beneath?

Is this project no longer active??

The project is definitely still active.  We're working on adding some new photos to the site.  In the meantime we welcome everyone to take a look at the set of photos currently on Broodmapper.

This is an interesting case with #1812.  That colony was actually dead at the time this photo was taken and those capped pupae would probably most correctly be scored as "Dead".  This is one case where knowing the condition of the colony tells you a lot about the state of the brood.

One indication that the capped brood is dead is the little holes that have been picked in the capping.  You'll often see a hole in the center of the cap if the workers are still in the process of capping over an old larva.  When you see holes that are not in the center of the cap, and are kind of ragged looking, that is a sure sign that the colony is failing and those capped brood are never to emerge.

Many thanks, Reed.

Mapping was going pretty smoothly until I got to that frame. Perhaps
something about this could be added to the help window for capped/dead
cells. (Unless I missed it.)

A couple suggestions for improvements:

1) Show a cumulative count of scored cells. You show the total at the
start (e.g. 120) and you show sub-totals for the various states, but the
only way for me to be sure I got all cells is to click on 'Next' or add
up the subtotals.

2) Give someone the option to skip a difficult frame. Not that saving
the most difficult for last is an optimal work approach, but it might
keep someone from giving up if the going gets too tough.

3) Here's something I discovered by accident (works in Google's
browser): You can click and then drag across multiple cells to score
them all at once (great for large areas of capped brood, etc.)

Best wishes from Berlin,

So (just found one), how does one score this? Old brood or capped? I'm going with capped as most of the surrounding cells are capped and the larva still looks viable: #001196 2011-08-06 (upper-right corner).

That's a judgement call on your part.  I'd call it capped.
