I often encountered a particular family of flies that had their eyes on extended stalks. Their heads resembled a hammerhead shark, which led to many calling them the hammerhead flies.
The Stalk-Eyed Flies belong to the family Diopsidae. The extended stalks occur in the males, and are sometimes completely absent in females.
The ones I found seem to have shorter “stalks” and had the same hammer-styled heads, so I’m not completely sure that they belong to the same family as the Stalk-Eyed Flies.
Here’s a video documenting how they pump their stalks to their full lengths after emerging from the larva.
This article documents an encounter with another similar looking fly.
#1 The bizarre head
#2 Face to face. Their eyes were not as wide apart as other Stalk-Eyed Flies
#3 Close up shot
Just a short trip, so just a few other finds. 🙂
#5 A family of newborn Thrips (Order Thysanoptera)
#6 Flower Chafer (Cetoniidae)? Not sure.
#7 Bess Beetle (Passalidae), likely to be Aceraius rectidens.
#8 Closeup on the Bess Beetle’s head, showing the comb-like antennae
#9 A really tiny Praying Mantis. There were quite a lot of them the day before, but when I got to the spot, only 1 was left.
