Wasp, Black and white striped abdomen with fibonacci sequence spacing.
Portland, Oregon, USA, Multnoma County, Oregon, USA
July 24, 2018
Size: 1/2"+
The hive of wasps had built their nest in a filbert tree stump, below ground level. Since they were very close to our back porch and stung my girlfriend twice with serious welts, the last of which left a mark 2/3rds the length of her shin bones, we had to eliminate them. I have never seen welts that size from a wasp sting before. Please help identify. It has been difficult to find images to match.

These are Vespula consobrina
The blackjacket. Their nests are typically smaller in size and adult number than other yellowjacket species, but of course they will still readily defend their nest when disturbed.
The specimen pictured here is actually a male, incapable of delivering a sting. You can read more about this species in the guide here:
