Thank you all for comments and ID.


Its a lampyrid.
First, compare overall general appearance:




That pinkish coloration is very common in lampyrids, but it is hard to distinguish lampyrids from lycids in pictures sometimes.

If you have a specimen on hand you will see that Lycidae actually have 2 pairs of mandibles, 2 segmented antennae, and no epicranial suture.

Lampyridae have 1 pair of falcate mandibles, epicranial suture present, 3-segmented antennae, and luminous organ situated on the venter of abdominal segment 8. (With the exception of the CA species Pterotus obsuripennis which has its organ on 7 and 8)

Phengodidae are drastically different looking and have 1 pair of channeled or grooved mandibles, no epicranial suture, 3-Segmented antennae, and a pair of luminous organs on abdominal segments 1-8.

All of this is from Immature Insects Volume 2 :)

Moved from ID Request.

Firefly larva of some kind., I suspect.
It looks a bit like this one:

Phengodidae vs Lampyridae...
I can't tell...yet.

Ah, yeah....
