what kind of caterpillar is pale grape green, somewhat translucent, with a mushy convex green face and a single long green spike at its other end? it was on a giant onion i'm growing. no stripes or spots, not hairy or spikey (except for the aforementioned one at its bottom end, i mean,) and without any distinctive marking at all. i've been looking at pictures of cabbage worms and whatnot on google all morning and haven't found one that looks like mine. well i put my hands right around him, by accident, when i thought i was wiping a bit of sap or resin off a leaf and found it was wriggling grub i was holding. i think i stunned him, that was when i dropped him, which i did, but i did let go in a hurry, which showed no presence of mind and all that, i am ashamed to say. then i had to stop the men from stomping on it, and had a long job scooping him up with two stiff cards without getting my finger run through, and then to let him go in the park.
