Hello my name is Ramon Ruiz am Spanish Tarragona (NE Spain). I would like to know which species it belongs to this Chrysidae I found on a beach in small galleries shoves sand. Thanks
your specimen is not a Chrysidids, even if it has some metallic colours. It's an Apoidea, belonging to the Halictidae family. You can ask for a better ID to http://www.forum.hymis.de/
