Sort of a weevil shaped insect, bright red/orange and black with bright white spots on body and legs.
I’ve never seen one of these before, and can’t find one on the web searching several sites. Do you know what it is? Since I can’t find it in searches, wondering if it’s an introduced species. Found it on our deck post afternoon of July 15, 2017. My property has a small woods on two sides.

Immature Spotted Lanternfly

Dear Olin,
This is not a good sighting.  Years ago we identified this Asian creature as an immature White Cicada, and upon searching BugGuide records, we learned it is called a Spotted Lanternfly and “native to China, India, Japan and Vietnam; invasive in Korea and in our area (PA; confirmed in Berks Co. Sep 2014)” and “SIGHTING REPORTS WANTED: Experts are working to delimit the current population and find new infestations of this species. Please report sightings on the Pennsylvania Dept. of Agriculture website.”

Immature Spotted Lanternfly

Thanks for the quick response.  It turns out that the spotted lanternfly is known to exist in my township, and I was simply unaware.  We are instructed simply to kill any we encounter, but I reported it none the less.
Had it now been for your site, and response, I would still be unaware of the threat.
Thanks again for your help.

  11. Dorothy A Croxton says:

    Just this week (July 4), I have seen these bugs. They are both red-and-white-spotted and black-and-white spotted. I have only seen them on them on my concrete decks (front and back) and my stone walls. It is hard to swap them, because they hop. Most of the time, I am able to step on them. Is there any bug spray that can the used to kill them?

  12. Dave says:

    Found out these are lantern flies. I’ve been using DE with some success. I’m also hearing Dawn dish detergent may work too.

  13. Linda says:

    I just saw a black one with white spots yesterday in Chester County near Delaware state line. It was walking on my gerber daisy. After I saw a post about the lanternfly I went to look for it and could not find it. Does it destroy trees and plants?

    • bugman says:

      They are considered an invasive species that will most likely have negative agricultural and horticultural ramifications in their new range.

  14. Dave says:

    I tried using Dawn dish detergent in a spray bottle with a water/Dawn ratio of about 5:1. Sprayed a couple dozen of the flies late yesterday and they clearly did not like it. Today there were only two of them, so I hit them with the spray. 🙂
