My Greatest Adventure With Giant Insects

Before the Doom Patrol took over the title, My Greatest Adventure had menaces that the ordinary humans of Earth had to face...with a bit of a science fiction bent.

Here, two covers by Dick Dillin and Sheldon Moldoff, with humans facing a giant beetle with the transplanted brain of a scientist (#41, March, 1960)  and being taken away by giant ants (#55, May, 1961).
