Aloha all,
I'm wondering if anyone else has noticed a particularly vicious, relatively new species, the stinging nettle caterpillar? These buggers have spines that poke you and burn upon slightest contact, then turn to an insanely itchy spot for weeks... at least that's what my reaction is. They camoflage brilliantly... I'm wondering if their recent appearance in my yard doesn't have something to do with the brown spots on various palms in my yard, a brown sandy type substance is collected on the backs of many of the leaves. Any one else have either of these issues? There's a reference to them back in November, but no discussion after that.

Thanks Damon,
And what do they do when you report them?

OK, the number for B.I. changed to 981-2823. They recommend Bt to treat, but only after proper identification. Bt is rather specific in the things it will treat and, from what I've read, it is a safe alternative to nasty chemy's. The nettle's pupa is the size of a small seed and look something like the inside of a coconut husk, a bit hairy. Often found on the undersides of the fronds. It takes about a week for bt to work, as it works when the caterpillar eats the leaf... Not such a good solution in the rainy season then... Outdoor lighting at night with soapy water under the light can drown many of the egg-laying adults.

The lady I spoke with also said that after a sting the best thing they've found to treat it is Dawn dish detergent, not another kind, just Dawn (hmm...). But I still am not sure why the brownish granules on the underside of the fronds... Perhaps it's another issue all together...

What does a Stinging Nettle Caterpillar morph into[:0] [?]

Stinging nettle caterpillars morph into a dirty brown moth about the size of a dime. We have dramatically reduced our infestation level by using those bug zapper lights. They are essentially worthless in combatting mosquitoes, but they kill LOTS of those moths. Also, another way to lessen the effect of the stings is to make a paste of vinegar and baking soda and apply it as soon as possible after contact. Mix some vinegar and soda, and once the fizzing subsides, take the pasty residue and apply liberally to the sting. Leave the paste on there until it dries and flakes off on its own. This reduces blistering and the duration of itchy discomfort in the days to come.
Cheers,
Jerry

Thanks Jerry! I'll be prepared next time I get stung! I thought of the zapper, but figured that would kill more than those wicked things, so I decided against it. And that ZAP! always bugged (pardon the pun) the heck out of me...
