The following story may well turn up on the ABC's popular Gardening Australian television show in the Frequently Asked Questions segment . It runs thus :
I have a green finger , should I poke it in a dainty dish of succulents when I notice that something seems to have nibbled the leaves ?
Answer : No-silly Greenie-because it could be a large ,green ,greedy,stinging caterpillar , see above, and when you touch it with you r dainty index finger you will yelp madly with pain and your digit will swell up and turn red like a waratah .
Incidentally, you have a snake loose in the front garden , do not poke it with your finger !!!
