In the rough dry grass of the Firehills during the long lazy days of summer we might glimpse the jewel like beauty of a Ruby-tailed Wasp. These small colourful wasps are cuckoo species that are associated with specific hosts. A visit to the Firehills this week has seen two species of Hedychridium. One has a dull red abdomen and is a little larger, Hedychridium roseum is frequently found in open sunny areas and is closely associated with a Crabronid wasps as its host. The second species was even more colourful but a little smaller. It is always worth keeping an eye open for Ruby-tailed Wasps as their colour never fails to please.
