The posterior end of the abdomen is club-shaped. The females are 2″ to 2⅜″ long, relatively common, and distinctive. The abdomen is long and slender. It has six segments and is five times the length of the rest of the body. The hindwings of both sexes are ⅓ the length of the forewings. |

Location: Saint Paul, MN I'd never seen or heard of this until late last night when one (female) flew about my bedroom as I was about to go to sleep. Was startled by its appearance after getting a clear view of it with my glasses on. Had to find out what it was. Have lived in Minnesota my entire life (51 years) and this was a first. |

Just found your site when trying to identify an insect we have never seen before. We found photos and made a positive ID - the bug we found is the female pelecinid wasp. We noticed that there were only three areas listed where this insect has been found in Minnesota. We found the insect in St. Louis County in the Side Lake area, more specifically, at Perch Lake. Just thought you might like to know about where we found the insect. |

Hello MinnesotaSeason.com!! I killed 3 female pelecinid wasps in Pennington County, ... if you want to update your locations spotted. One crawled at me fast, like a scorpion about to attack... This is the first time I've seen them. I had to figure out what they were. Thanks for the site |
