Firefly emerging from larval stage? - Pyractomena

Firefly emerging from larval stage? - Pyractomena
Baton Rouge - BREC Bluebonnet Swamp Nature Center, East Baton Rouge Parish, Louisiana, USA
February 7, 2009
Size: about 3/4 inch
Found on the trunk of a Hackberry tree.
At 17:00.
About 75 deg F.
More larvae and emerging adults within inches of this one.
Head shape and colors remind me of our fireflies.
I say emerging adults but I can't find the wings.

I will attach a photo of a nearby larva in a separate note.

Several individuals were located on the same tree trunk.
Within a few feet of each other.
They are believed to be the same species.

How long before adult emerges?
Any idea on how long before the adult emerges from this pupa state?

When I returned the next day (2/8/09), there was little change, except that it was a little darker in color.
The first day there was some squirming movement, so I thing it was just emerging from the larval skin.

At least a few weeks
I had some larvae I reared out for an immatures class and I think it took 3 weeks or so... (Sorry this was spring of 2006 so I don't really remember) Plus that was indoors with a constant temperature.

Pupa.
Yes, a pupa of a species of Pyractomena. Very nice!

No wings...
...because this is a pupa, not an adult. A lot of beetle pupae look just like pale, wingless adults. Neat find.
