They look like pantry weevils. Of course they look like grain husks too.
Hop oil film with what looks like beetle larva. Another guy just showed that earlier in the week. Possibly from grains?
My father says, "hobbies are supposed to cost money".
I'd skim them thangs outta there first. Any grains you used must've had beetle eggs in them?
Look like husks to me.
Or eggs about to hatch?...You can see antennas on them.
Lol looks like some of the bugs I see in the ocean... Lol 😀
Dive Often! Play Hard and Have a homeBrew!
OP, is it possible a bug laid eggs in your chiller? Seriously, I've had this happen.
