Leaf beetle

Diabrotica sp.

Description:

Leaf beetle (Chrysomelidae).

Notes:

Photographed centimeters away from an individual that looked just like this: http://www.projectnoah.org/spottings/212.... Same species?? I have uploaded a number of very similar beetles which I believe are all Diabrotica sp, in the hopes that someone can help me sort them out down to species level...

Agree with you, Boris. The bad issue started 4 or 5 years ago. In the meanwhile a little, little bit wiser and more careful.
Thanks for your assistance!

Criteria:
- body more compact, harder than in Diabrotica;
- pronotum constricted in middle, no lined side border;
- head with sulci inbetween eyes;
- elytra usually with some puncture series.

Same or a very similar as previously commented by Boris:

Again my question: criteria for separation between Lema sp. and Diabrotica sp. Texture is in my eyes quite different ("no glaze") and markings as well not as "sharp" as in Diabrotica. Any other thoughts, Boris?

cf. Lema sp. - mimic of Diabrotica.

bayucca, I have wondered if this one also is Diabrotica - what is your opinion?

Nice shot Anne

That's great, bayucca - I will add them all to the mission right away.

I just created a mission for Diabrotica sp. of Costa Rica and Panama. Unfortunately we cannot include the ones from Mexico as well (out of range). I have created this mission for documentation and ID purposes with the knowledge that we only will have very few examples included. But it is an interesting and beautiful little jewel and maybe, we can help to solve all the ID mysteries...
Please, include all of your Diabrotica in my mission and invite also others to join, but only from this species and within the range! Thanks a lot!

I suggest that you take Diabrotica sp. as ID.

Yes, bayucca, I do realize that the Diabrotica are very difficult and most will probably remain unidentified. Would it be better if I take them off the "unknown spotting" list and simply identify them all as "Diabrotica sp"?

There is new research of Diabrotica done in the next time. Many of them will be unid until the final results.

Thank you valgaavmiko, I posted a number of these very similar beetles in the hopes someone would help me sort out one Diabrotica from another...if I can not get a species ID I will just have to label them all as Diabrotica sp.

All of your beetles that appear this way are Diabrotica. I found some collections containing specimens like that in your photo but they were all undescribed species or they were unidentifiable by the collector.
