Thread: Is this a Wasp?

  1. #1

    Default Is this a Wasp?

    Hi,

    In South Wales, UK. It was about 5-6 cm long and did not fly away or move while I looked at it up close. The yellow bands on the abdomen are very faint and almost white. The head is completely black and the antennae are orange. Two sets of wings, two sets of main legs with large thighs. Is this a predatory wasp?

    Please help.

    I didn't find the right solution from the Internet.



    Thanks

    Looks like it may be a species of the sawfly group (Symphyta)? Same order (Hymenoptera) as wasps.

    sounds like a "wood wasp" with a long ovipositor, belonging to the Ichneumid family, we get them a lot here, boring into new wood with the Ovipositor and the grubs doing quite a bit of damage to the wood, easker1

    The one in the photo didn't have an ovipositor. Wood wasps are members of the sawfly group, though - Symphyta. I reckon it is something from the Symphyta - they don't have 'wasp waists'.

    Yeh - just looked more like the various photos of sawflies, than a particular wood wasp, Derek. As I said, they are the same group anyway. We can put it down as being a member of the Symphyta.

    I claim no expertise in these things but according to my everyman's book of creapie crawlies it is most likely to be a Greater Horntail, also known as a Giant Wood Wasp. It's larvae live in rotten wood and are preyed upon by the Large Ichneumon which lays it's eggs in them. Eaten alive, yuk.

    As already said, the thing is something in the Symphyta, which are the sawflies, which includes woodwasps... which includes the greater horntail.

    This is the beastie in question for those who didn't see it...

    Main reasons I didn't think it was a wasp, Sandy:

    It has clubbed antennae.
    It doesn't look like it has a 'wasp waist' - though it's difficult to be sure from the angle given.
