Placing of two Beehotels in the project area.

 

Beehotels were set up with reeds of variable length and diameter for cavity nesting Apoidea
(Megachilidae and carpenter bees) and a box filled with soil for ground nesting Apoidea (sweat
bees, mining bees).

 

 

June 2013

Nest occupation monitoring, performed monthly from February to September 2013

 

Successful occupation is verified at sight (surface of the hole closed with a mud cap) or using a
small rod and a flashlight when the closure cap is not visible.

 

Checking the nests, it is possible to identify the most common parasites.

 

In the hole at the middle you can see a bee fly exuvia (Anthrax anthrax), a parasite of the larval
stage of some solitary Apoidea.

End of field work

For this year we have finished field work with insects observations on plants in the study area.
Blooming during the end of Summer here is charachterized byPeucedanum cervaia (Umbelliferae), together with Centaurea bracteata and the hemiparasitic Orthantha lutea.
Plants germinated at the Botanic garden and later transplanted in the area show a good flowering success as well, like Veronica barrelierii and Cephalaria transsylvanica.
We will be back with field work in 2014, see you soon!

Some of the solitary bee nest have moved to the CRA-API labs for the identification of nesting bees
and parasites.
