I just thought I’d send this photo along to you because it was something I’d not seen before. I was walking on a lakeside trail looking for dragonflies when I saw this large robber fly ovisositing. She was so large that initially I thought she was a small dragon. I was able to crouch down and watch her for several minutes.

Hi Deborah,
Thank you for supplying us with this marvelous documentation of a Robber Fly in the act of ovipositing.  According to BugGuide:  “Adults lay eggs in the soil or in plants. A few, such as
Mallophora and Megaphorus form an egg mass on a plant stem. Larvae often predatory, consuming eggs and larvae of other insects in decaying matter. Typically overwinter as pupa, emerge in spring. Life cycle is 1-3 years.”
