Cordulegaster species in NE Bulgaria
The visit of Boguslaw Daraż in NE Bulgaria ended up with 5 new localities for both Cordulegaster species known to occur within the region – picta and insignis. C. picta obviously dominated in four of the places and missed at one site only. Both species have been encountered at one site, which is the second place where they are known to co-occur. The two species are spectacular creatures and a great thrill to all nature lovers. They always impress with their large bright bodies and fast flight. Moreover both are rarely seen even in the places where they have been previously observed.
Another record from this region comes as a picture taken in early May by Uwe Holtfreter. It shows a newly born female Cordulegaster which remains unidentified so far. The greater number of C. picta records from this area infer it as the most likely species caught on the photo. |
Cordulegaster insignis’ “invasion” along the Danube River
New data on Cordulegaster insignis’ distribution along the Danube River were collected by Dr. Yordan Kutsarov. He confirms the inferred early hypothesis on the species’ mass occupation of the Bulgarian stretch of Danube River. C. insignis has been discovered in a new locality in NE Bulgaria and the Danube River’s middle section near the town of Nikopol. It will possibly be observed in other places near the river along the whole stretch in its Bulgarian part. Recent conversation with Cosmin Manchi encouraged the search for this species on the Romanian part of the river where the species has been established in 1971. |
Brachytron pratense back in NE Bulgaria
Brachytron pratense is a species that normally does not attract so much attention. It is widely distributed over great part of Europe. However, it reaches its southern limits to the Mediterranean area and naturally the records from these zones are scarcer. It is even more difficult to be found as the species flies early in spring when not so many collectors are active on the field yet. For Bulgaria B. pratense is known from 11 places as most of the records come from literature sources published in sixties. All work after 1990 revealed three news places only for the whole country.
The most recent data is due to Dr. Yordan Kutsarov’s investigations within NE Bulgaria (within “Kalimok-Brashlyan” Protected Area). B. pratense was observed early in the spring of 2008. This is the fourth new place for the species since 1990 and the second for this region after a long period of 40 years since the publication of Prof. Beshovski in 1965.
