Dear Bugman,
I found this insect in the fields of Malta and have looked all over the internet to try and identify it. Could you please help.
Thank you

Mammoth Wasp

Dear S,
This magnificent creature is a Mammoth Wasp,
Megascolis maculata.  According to the Times of Malta:  “The mammoth wasp is the largest wasp you will encounter in Malta or, for that matter, anywhere in Europe. It belongs to a family of wasps known as scolid wasps and, in fact, is also known as the large yellow-banded scolid wasp.”  According to Maltese Nature:  “Only females have stings. The sting is used mainly to paralyse the white larvae of Europe’s largest beetle; the rhinoceros beetle. She then lays a single egg in the larva’s body. When the egg hatches, the wasp larva starts to feed on the larva’s internal tissues. It eventually kills it and continues eating it until nothing is left but an empty skin. When fully grown the larva forms a cocoon and emerges in spring when the air has warmed up sufficiently.  In Maltese the mammoth wasp is known as qerd iż-żaqquq. Qerd is Maltese for destroyer but I could not find the meaning of żaqquq. I assume that as this wasp kills the larvae of the rhinoceros beetle żaqquq could be a lost name for this insect which nowadays is known as buqarn kbir. ”  According to Project Noah:  “Meeting with this flying monster probably wont let you calm down for a while. The larger female (may reach 5.5-6 cm) can be told apart by her yellow head and short antennae. The male has a black head and longer antennae. Both have two yellow bands on their abdomens, which can be divided to form 4 spots as it is shown on the photos. Nevertheless, they hold no harm to humans despite their size, in contrast to common wasps and hornets. Indeed, mammoth wasps do have stings, but not for self-defence or nest protection (in fact, they are solitary wasps).”  We will be post-dating your submission to go live to our site later in the month while our editorial staff is away on holiday.

Dear Daniel,
Thank you so much for replying back, it was a very interesting read and I am glad I have a name for this beautiful creature.  Kind Regards
S
