Dear Collectors,
I have recently finished preparing a group of Euchirinae specimens which will be used to create a "wall display". I am now ready to design the display and select the frame, but I cannot find much information on this group. I do have data for each specimen of course, but I always like my displays to have a "design theme" which represents the group.
This group will include most of the Cheirotonus, Propomacrus and Euchirus species. I do not have C. jambar unfortunately!
It would be extremely helpful if anyone could give me any kind of information on this group(or suggest websites, etc.), such as:
What type of habitat do they live in?
If they live in forests, what kinds of trees do they inhabit/feed on?
Where do they "hang out" typically? On tree trunks?
What do they eat?
Are they diurnal or nocturnal?
Basically any information could be extremely helpful.
I would also love any input for a title for this display. At this point I was simply considering "Long-Armed Beetles of Asia". I like to keep my titles short, simple and free of scientific names. All specimens will have individual data labels.
Thanks so much for any help!

Hello Not very sure about their biology, but what I can suggest is that if you are going to put Propomacrus bimucronatus you have to say in the title "Long-Armed Beetles of Asia, and SE Europe"  Regards |

Thank you for the message - I do appreciate it and it made me do some more investigating!!!
Are you sure about this? The pair I have is from Turkey, near the border to Syria. I am definitely no expert on Geography, but everything I've read says this would be Asia, or Asia Minor. All of my Google searches indicate that only 5 to 10% of Turkey is actually considered to be part of Europe and that area is not where these specimens came from.
Perhaps I keep pulling up dated maps or information.
If it is indeed from Europe I think I would prefer "Long-Armed Beetles of Eurasia"!
Best Regards |

After a little more thought, I guess it would depend on whether I want to describe (with the title) only the range that the specimens within this display have come from, or include the full range which these species in general can come from.
Seems that it may be more proper to describe the entire range with "Eurasia", since P. bimucronatus can indeed be found in SE Europe.
Now I see where you were coming from Mr. Gomez!! Once again many thanks for your message!
Still wish someone knew a little about their biology. I know that they live in forests and the adults feed on tree sap and fermenting fruit, but so many other beetles do also, it would be great to have a little more detail such as actual host plant species!

From my personal experience traveling around in Asia looking for them is Cheirotonus from primary old growth rainforest above 1000M , Propomacrus from pine forest and Euchirus from old growth lowland rainforest but Euchirus dupontianus from highland old growth rainforest. Cheirotonus female will lay eggs inside hollow huge oak trees and adults will feed on fruits and tree sap. Females to males ratio are 7-10 females to one male. All Cheirotonus, Propomacrus and Euchirus are nocturnal. They also have this really distinctive smell when they are alive. Attachments:

Propomacrus bimucronatus also lay their eggs in hollow trees and the larvae feed on the mulm. I only have reports from oaks and plane trees but not from pines.
There is also a second species from Europe: Propomacrus cypriacus.

Hello Yes, panacanthus, my comment was oriented that the presence of P. bimucronatus is documented on Greece, wich geographically is considered within Europe. Sorry, I dind't explained myself very clearly. Turkey can be more problematic in those terms, as indeed it's partially in both continents, Europe and Asia. Cyprus where it's also present it's also a bit doubtful, although politically it's member of EU. Nevertheless for geographic distribution I would use only geographic criteria. About the biology of these species, considering the P. cypriacus, whose biology should be very similar to P. bimucronatus, I found this small pice of info in the UICN red list, wich can maybe give you a hint about the genus biology: www.iucnredlist.org/details/full/157773/0Regards |
