The giant horntail
Urocerus gigas (Lat)
Le Sirex géant (Fr)
De reuzenhoutwesp (Nl)


The last tergite of the abdomen has a strong, projecting spike. The ovipositor is longer and also projects posteriorly. Female giant horntails lay their eggs in trees. The larvae bore into the wood and live in the tree. They typically migrate to just under the bark before pupation.


From left to right, between the 6 legs note :
1 - the ovipositor (inserted vertically in wood and laying eggs),
2 - its sheath,
3 - The projecting spike from the abdomen.
My new ring flash has been very helpful as it was dark with counterlight.
crop: 5% of the right.

Thanks for looking

Hello Jean Marie
Very interesting insect capture with excellent details and low POV. Well done

Hi JeanMarie,

absolutely great, this shot. The species is not often seen and you present it in its fantastic stance of boring into hard wood. You confirm thar t the use of flash is almost always an improvement. Well done!
Best regards
