Wow! Thats a pretty big wolf. I would be afraid of it throwing a defensive bite while your chameleon was reeling it in or starting to eat it. I don't feed my chameleon spiders for that reason, but I have seen where a lot of people do feed chams spiders with no ramifications. Bet they're pretty tasty.
Jannb was talking about one of their chameleons eating a big bumble bee. It could have been a male carpenter bee. The cool thing about them is they have no stinger! I have actually fed one to my Senegal, but decided to avoid any further bee meals and recommend avoiding it since it may desensitize your chameleon to bees. And I know around my house at least, I have way too many types of bees for my Peppers to decide they they all look good.
