Dobsonflies (Family: Corydalidae)
Dobsonflies, also known as hellgrammites in their larval stage, possess highly-mobile heads that grant them the same 360-degree range of motion as praying mantises. Both adults and larvae exhibit this impressive agility.
Antlions (Family: Myrmeleontidae)
Antlions, with their long, cone-shaped pits or traps built in sandy terrain, surprise their prey with lightning-fast strikes. To facilitate this hunting strategy, antlions can swivel their heads a complete 360 degrees.
Owlflies (Family: Ascalaphidae)
Owlflies, resembling delicate flying dragons, boast incredibly flexible necks, permitting them to turn their heads like praying mantises, scanning their surroundings with utmost proficiency.
Scorpionflies (Family: Panorpidae)
Scorpionflies bear an elongated rostrum resembling a scorpion's tail at the rear of their heads. Despite carrying this tail-like structure, they don't let it hinder their head mobility. Scorpionflies enjoy the same full-range movement of their heads like praying mantises.
So, while praying mantises indeed stand out for their head-turning prowess, they are joined by these other diverse insect species that share this special capability.
