I spotted this odd looking bug in my porch a few weeks ago. It looks like a wingless fly with a hairy tail that wouldn't look out of place on a fly sized horse.
My Google-fu failed me so I turned to JustAnswer. Random insect identification isn't your typical veterinary question but Rebeccavet came through for me via a taxonomist in Kenya and told me it's a Leafhopper (Cicadellidae) nymph. Given this information Google Images confirmed that this seems like the most likely possibility.
(Full disclosure - I work at JustAnswer.)
