Hi, this big flying insect comes into my house the last 2 days. It is not aggressive and about 5 cm long.
I made the pictures through a glass bowl.

Mammoth Wasp: Megascolia azurea

Dear Ricci,
This is a magnificent wasp, and we were immediately struck by its resemblance to the European Mammoth Wasp, which is represented in our archives and identified as either
Megascolia maculata or Scolia flavifrons.  We may need to go back through our archives and make some corrections.  So, with that as a point of departure, we believe we have identified your individual as Megascolia azurea  on the HK Wildlife Forum and we found an example identified as a Digger Wasp from Hong Kong in our own archives.  This image from TheBugRoom indicates that only the female of the species has the red head, an example of sexual dimorphism.
