Much appreciation and gratitude to Michal Grabowski cedryk for the correct identification of this Patent-leather Beetle Odontotaenius disjunctus

NOTE: the grubs are the edible larva of beetles.
NOTE: About 300,000 species of beetles are known.

The Patent-leather Beetle is a large beetle which can grow to just over an inch-and-a-half long. They are shiny black and have many long grooves on their elytra (outer wings).

They have a small horn between their eyes, and clubbed attenae (means they have little knobs on them).

Patent-leather Beetles are usually found under, or inside, old logs or stumps. They eat old decaying wood.

These beetles make tunnels in the wood, called "galleries."

Inside the galleries, the beetles will mate, lay eggs, and raise their young.

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.

Patent-leather Beetle larvae take a year to develop. When the larvae are ready, they become pupae (like coccoons). Adults hatch from the pupa.

Many Paten-leather Beetles may live together in a colony in the same log. Adults can live over a year.

Patent-leather beetles like to eat logs of certain trees. Mostly they eat deciduous trees (ones where the leaves fall off in the fall), such as oaks and elm. Info Source Same as above Patent-leather Beetle link

World Book Encyclopedia:
Beetle is the common name for members of one of the largest and most important groups of insects. This group is the Coleoptera, a term meaning sheath-winged insects. The beetles received this name because of their though, horny front wings which serve as sheaths and protect the more delicate underwings used in flying.
The name beetle means biter, These parts are jaws which are well adapted to seizing and chewing the beetle's food.

Hello Dave,
Wonderful captures and presentation.Colors,sharpness,details and note are excellent.

I am not shure about the adult [it is not Pterostichus melanarius for shure and I think it is not a ground beetle] but it is not a ground beetle larva. Carabidae has different kind of larve. Grubs are larvae of Scarabeidae or Lucanidae but not ground beetles.
Best wishes

I like the presentation but you must change the note

Intéressant assemblage.
Bonne journée

Hi David,
Great image of this insect. Perfect details, exposure and collage.
TFS, José M.

Dear David,
This is not a ground beetle, the adult belongs to the bess beetle family (Passalidae), and the species is Odontotaenius disjunctus, known also as horned bess beetle or patent-leather beetle - more than likely these are its grubs. I know this species well as I was collecting it several times in Mississippi, overwintering in decaying logs.
In fact Pterostichus belongs even to another suborder Adephaga, while passalids are related to Scarabeidae and placed in Polyphaga.
Best greetings,

Hi Dave,
I can't say that I am a grub-lover,
but these critters sure are interesting
and have a certain beauty of their own.
You sure captured them artfully,
with excellent focus and exposure.
See something new everyday. : )
TFS. : )

Hi Dave,
I see the new macro lens has arrived. Looks like you are starting off very well in the macro world. Nice sharp detail and a good fill flash exposure have these looking excellent. Great presentation and very informative notes.

Not a life to desire! Interseting, but kinda ugly creatures! At a insect fair for kids, they were selling beetles to pin to your clothes with a chain attached to them, decorated with jewels, etc. (in the USA). I wonder if it was these. They ate only rotten wood.

Hi Dave,
even thought they give me the creeps it is a very interesting post. Very well presented in this split frame composition, very well documented.
Your captures are full of detail and of very good quality.

Hi Dave, this sure is an interesting subject to photo.You have caught these insects well ,as they so very organic and alive.The translucency of their pallid white skin shows very much detail and the adults are very clearly photoed as well,nice. Bob

Hello David,
I found one of your pictures that I didn’t comment yet :)! This is an original presentation of those tiny creatures; well realized with good use of flash that created nice brilliance and brought of some sharp details. Your notes are also interesting. Thanks!
