Mannequin senses

I drew my bugs around me to conceal my movements as I rolled to one side, set my feet under me and sprinted to his left.

While still beneath the cover of my bugs, I was struck from behind and knocked face first to the ground. The surprise was as bad as the pain.

Through the swarm, I sensed him approach until he stood with one foot on either side of me. I felt him wind his fingers into my hair and pull my head up and back. I struggled, trying to catch him in the knee with my baton, but he wrenched me to one side, and I felt a blade press against my throat.

[...]

He could sense me somehow. How? It had been reckless of me to assume that he used sight to get by, especially when he didn’t have eyeholes in his mask. The fact that he hadn’t noticed I was faking meant he wasn’t relying on sight, or his sight was limited enough that he couldn’t make out the lack of blood through the cloud of bugs around us. If he wasn’t hearing my breathing, I doubted he had super hearing either.

Did he use radar, like Cricket? It would be my first assumption, except my bugs hadn’t heard anything of the sort.

No. This line of thinking wasn’t accomplishing anything.
