I didn't find a topic for them, so I decided to create one.
I start the topic with a photo of a female: Xylocopa pubescens Spinola, 1838
Egypt, Nile Delta.
Many thanks to Alex (u) 2611 for the definition.
I really want to see other species.

And what plants do you have iris associated with? That is, what does the nest chamber build in and do the imago have preferences for food plants?
I got the impression that many naturalists do not distinguish between violaceus and valga at all!?? Are they visually noticeable? We were literally obliged to enter valga in the KK of the Penza region (Animals, 2005) - although we have an abyss of points of her finds (my and Shibaev's data/map)! The most extreme view. In addition to old wood, it lives quite calmly and winters in the soil (slopes).

I don't know. I didn't even try to study the biology of these insects. Caught and all on it.

I identified already caught specimens at home, from books. For me personally, defining these species (violacea and valga)" in the field " is problematic. I tried to identify differences in the shade of the wings, the ratio of the width of the head and chest, the general shape of the body, and the shape of the head... All in vain! What visually appeared to be violacea ended up being valga and vice versa. So for me personally, there is only one way out - to catch and watch "in the hands" .

Xylocopa iris is not common and I can only say that one bee was caught on the flowers of Zygophillum fabago. In the Crimea.

Same bullshit. View houses at zoom level.

I have three specimens in collections, and I've seen two more, but I don't know the names of the plants I caught. All the material is from Crimea.

And what exactly do they have to watch?

But I don't know the names of the plants I caught.

Photos of plants ( if any) - in the topic by their definition.

As far as I can remember, females have to look at their hind legs.
In "green", these two types are easily distinguished even with the help of a regular magnifying glass.

By iris:
Previously, this species was known only in the Orenburg region (their CC). In the Middle Volga region, iris has already been caught several times in the Samara region! I wonder why this species was previously unknown?? The version about "warming" is somehow not very good...

Continuation URL #1 it turned out.
Male Xylocopa pubescens Spinola, 1838
Many thanks to lunkov(y) for explaining it.
Egypt, Nile Delta (unfortunately, no other data has been preserved)

Mda, warming is often blamed for what they could not find or determine before smile.gifIris in our region visits the flowers of various plants, last season I found pupae at the end of June in a dry stem of some compound flower. In general, it does not seem to me that there will be a direct choice of a specific narrow group of plants for "laying" cells - the stem is suitable for thickness, and that's fine...

I caught this species only a couple of times, and in both cases on areas of untilled tipchak-feather grass steppes in June. Nemkov also doesn't have many collections of this type, consisting of two or three points. I don't have any original information about imago wintering:) in an essay in the Kk of the Orenburg region, Nemkov writes that young adults spend the winter. Flying occurs during the entire warm season-known-at the beginning of summer, "last year's" bees fly, in the second half of summer, young individuals fly out.

Please tell me if I correctly identified this instance as Xylocopa valga? Fore wing length 20.5 mm, wingspan 50 mm. Caught in Saratov on August 2, 2002.

If the books do not lie, then the females of Xylocopa valga and Xylocopa violacea most simply differ as follows:

This summer, X. valga was celebrated in the Middle Urals in Yekaterinburg. She flew through the window of our lab and fell asleep under it. Instance in the collection.
