The Environment Agency–Abu Dhabi (EAD) announced the discovery of eight ‘new to science’ invertebrate species, which were scientifically confirmed earlier this year.
All the newly discovered species belong to the same family of wasps (Hymenoptera: Spheciformes: Crabronidae) and are known as “Digger Wasps”. The new species were discovered in the Al Wathba Wetland Reserve, Al Bida Protected Area, Barqa Saqoor Protected Area and Houbara Protected Area – all of which are part of EAD’s Sheikh Zayed Network of Protected Areas, highlighting the importance of a network of protected areas in protecting Abu Dhabi’s biodiversity.
Digger wasps are solitary wasps and females make a nest for their young. In the nest, the females will lay eggs on paralysed insects so when the young wasp larvae hatch, they have fresh food available. After feeding on the prey the larvae will pupate and eventually emerge from the nest as adult wasps. These adult wasps will then look for a mate and if the wasp is a female, it will begin to prepare and provide a nest for its own eggs.
The Agency’s scientists used Malaise Traps which is a net like structure mounted on a metal frame. This helps to catch flying insects and funnel them into a bottle with a preservative solution. Insects collected are sorted by EAD scientists and, in collaboration with international entomological experts, the long process of taxonomic research and publication is undertaken to describe a species new to science.
EAD has an extensive collection of invertebrates, and all specimens and discoveries are meticulously maintained in a database which will soon be available online for use by scientists, naturalists and even the general public, showcasing Abu Dhabi’s invertebrate diversity.
