Larva of the Patent-leather Beetle Odontotaenius disjunctus

This is a follow up to my Grubs 'N Beetles post.
Credit for the correct identification goes to cedryk

These beetles make tunnels in the wood, called "galleries." In the previous post you can see two adult beetles inside their gallery.

Inside the galleries, the beetles will mate, lay eggs, and raise their young. I rolled the log over and the larva remained on the ground while the adults remained in their gallery. I speculate that the larva and the gallery would have overlaid each other when the log was in its undisturbed position. I did replace the log after taking my shots.

Larvae hatch from the eggs; they look like white grubs. The adults feed the larvae a chewed-up mixture of wood chips and feces (poop). The larvae cannot feed themselves. The main reason I made this follow up post: you can actually see the wood chips and feces the larva feed on. Yum, yum??? NOT! Nature is truely amazing; if you needed this to survive, you could.

Well, I hope you don't mind my encore post.

Best Regards and thanks again to Michal (cedryk) for the help with the proper identification of this beetle and larva,

It really is a great close up shot, but man ..ewwwww...:o)
TFS though!
Donna :o)

Thanks for your comment on my photo " After The Storm" :o)

Hi Dave,
Kinda nasty to look at, but also very interesting to look at. Especially the see through kind of skin. You've captured great details and colors.

Hi friend!
you are presenting excellent macro working!
composition, POV, DOF, focus, sharpness and details are great! Take care Ana:)

This is one great shot.
Most unusual. Never seen one so close. It looks alive,
yes, ALIVE on my screen.
You have captured a great amount of details.
Very well composed & presented.
Loved your notes too.
Best regards, Mario.

Fantastic - don't see many images like this. Great colour and subject. Very well taken.


Hi Dave

I see you swiched subjects: birds to insects.
Great close up you caught here.
so this is how they maye those "Allien" movies serie, huh? ;-)

Cheers, Petru

Well done Dave.
Nice sharp detail and I like the translucent quality of the larva, giving a great look inside..
I will say that F/36 is perhaps a tiny bit of over-kill..F/16 here would've been plenty..
You know I'm not gonna leave ya alone ;)
Happy Holidays mf.

Hello Dave,

TFS Kyle

Hello Dave,
This is a really unusual post. You caught very good details on this larva as we can see trough its skin. It is interesting to see it in its natural habitat. This is an instructive post. Well done and TFS,

Bonjour Dave
Félicitations pour le belle éclairage et les magnifiques couleurs et les jolis détails sur cette larve ,c'est une belle présentation.
Merci pour l'envoie.....JP

Nature is so strange, who thought up all this stuff? There is a use for everything!

This is actually a Lucanid (Stag beetle) larva, due to the shape of it's... "rear". These are much more of a rarity though, so it was a nice find.

Bess beetle grub for comparison:
