This is a "giant".
Ichneumonidae Rhyssa persuasoria - body 30mm - 60mm from head to tail!
Searching for a victim in old weathered wood.

Starting to drill
There is some work to be done
Injection of a single egg into the larva of a wasp
I had just one minute of time....
Not long enough for better pictures.

Nice pictures!
I love these creatures - We call them ichneumonid fly, but they are actually relatives to wasps. :-)
But this is not Rhyssa persusoria - that species has distinguishing white spots/stripes along its belly.
This one is probably something from genus Dolichomitus (maybee D.imperator, but it's impossible to tell it by picture).
Last weekend I found another species of these large ichneumonids - Megarhyssa superba which has aproximately 100mm long body. Also beatiful insect, but I can't really show you pictures of it, because I had a dillema: to take a photo or to collect it, and I choosed collecting it, and later I checked out that it was only the second caught specimen of this species in Latvia. :-)

ok I am waiting for the third caught specimen of this species in Latvia.

D. imperator sounds good, I will try to be a little bit more precise next time.
These wasps are so busy, I need a transportable refrigerator next time!


ps -off topic- still waiting for the postman.

We can't be really precise if there are thosands of insect species who can be determined only after viewing under microscope, so don't worry say as you think and if there will be someone who knows better he will correct :-) Atleast that's how I do. :lol: And isn't it a way how to learn something new? :-)
