It's always bothered me that when people adapt Kafka's Metamorphosis they depict Gregor Samsa as a roach. Cockroaches do not undergo metamorphosis. They are born as nymphs which are just smaller wingless versions of the adult form.
Kafka writes that Gregor can only enjoy rotten food. Which also makes him not at all roach-like. Roaches strongly prefer fresh vegetables to rotten ones.
I always imagined him as a beetle. Which implies that the man Gregor was a larvae for all his pre-bug life.
