Millipede.
gen. Julus
Not biting, but spraying a poison that has not much effect on skin but can destroy the eye. When fully grown it is about 15 cm long and thick like a thumb. On soft ground it is usually a greenish color, on hard packed earth it is usually reddish. When lightly touched it will curl up.
Don’t go close to that millipede lest it spray (lit. urinates on) you.
