The caterpillar is especially dangerous because it blends in so well with its surroundings. It looks like it is covered in bark or moss. When we first saw it in Ecuador, it was camouflaged on a wooden bench. Luckily we saw it before we sat down. The Waira Churis and Felipe inspected it and moved it onto the ground. Felipe had told us not to touch it (and this was our first instinct anyway - would you purposely touch something that looks like that?) But really...it could have killed us? I doubt we could have reached medical help within the 15 hours it would take to finish us off, unless the Waira Churis knew of an antidote. We are glad that we didn't know all of this at the time, or I might not have slept very well that night (though we did have a bug net over our bed, thank goodness!)
We're no caterpillar experts, so we can't 100% guarantee that it is the same caterpillar, but it sure looks it to us! And if that is the case, it has made its way from Brazil to Ecuador!
