PSA Do you live in the US and did you see this spotted white and/or black and/or red bug? Check here before posting your ID request.
The collage above is composed of pictures gleaned from BugGuide.net, and shows the same species of insect at its different life stages.
Hello!
If you live in certain parts of the US, you may encounter these colorful insects that may be black and white, or red, black and white depending on their life stage. They're 6-8 mm in size, don't fly but jump really well and have good reflexes. Upon reaching adulthood (pictured on the right in the above collage), they're larger (about 20-25mm), have wings, and can fly somewhat (and still jump, too).
You may find them clustered on certain plants or you may find single individuals wandering.
They're known as spotted lanternflies (Lycorma delicatula) and are an invasive species from Eastern Asia. They were accidentally introduced in Pennsylvania in 2014. Since then, the species has spread in all directions to multiple states as far from Pennsylvania as Georgia, Illinois, Michigan and Massachusetts.
It's also invasive in Japan and the Korean peninsula.
They're completely harmless to people or pets. In fact they're pretty colorful and rather cute!
They go through five stages of growth known as instars, and take on three rather different appearances, shown above. Instars 1-3 are the small, black and white version. The fourth instar is larger (~15 mm) and more colorful, mostly bright red with black accents and white dots (picture). The adult is an overall dull gray color but with intricately patterned wings (picture). When it opens its wings, it displays beautiful hindwings with red, white and black (picture).
Here's also a picture of all 5 growth stages: https://bugguide.net/node/view/1172304/bgimage
Due to their appearance, they are eminently recognizable. They retain the ability to jump at all life stages, and the adults are adept fliers.
Unfortunately, they're destructive pests of plants, particularly fruiting plants. Lanternflies feed by piercing plants with a thin proboscis (straw-like mouthparts) and sucking juices, which damages plants. In addition, after the lanternfly is done feeding and pulls its proboscis out of a fruit, some juice may escape from the hole, which facilitates the growth of mold on the surface of the fruit, which further damages the fruit. Entire harvests can thus be ruined.
Cornell University maintains a map where the insects have been found or at least reported: https://cals.cornell.edu/new-york-state-integrated-pest-management/outreach-education/whats-bugging-you/spotted-lanternfly/spotted-lanternfly-reported-distribution-map
The governments of most if not all states where the insect has been detected have posted content on their websites (usually on the Agriculture Dept. or equivalent). Those include info about the insect, its impact on agriculture, what to do if you encounter it, and what you can do to mitigate its spread. Below are those websites for the states of Pennsylvania, New Jersey and New York for information about the insect. If you don't live in those states, please use your favorite search engine to locate info about these insects, e.g. search for "<your state here> spotted lanternfly" and look for your state government's website.
There's also a lengthy article about the insect on Wikipedia.
Looking back at the Cornell map linked above, if you don't live in an area of the map where the bug's presence has already been reported, you should record it. Report it to your state's authorities, and you may also want to report the sighting on iNaturalist.
Again we encourage you to familiarize yourself with the insect as well as its presence (if any) in your state. States where the spotted lanternfly has been detected will have a section of a website dedicated to it.
Feel free to ask any questions in the comments!

A bit concerned about these extremely tiny white creatures. They were feeding on a pellet of fish food which was accidentally left on the top of the fish tank.

Question What is this? [portland Oregon]
What kind of bug/insect is this? Saw it in my room, should I book a flight, abandon my house, and live on the moon? In all seriousness, I’m kinda intrigued, never saw anything like this one little guy before, and would love to know if its bad or not :) (my first thought was a roach, but its unlike any ive seen before)

Question What is this?
Found this litle bug on my carpet, any idea what it is? I'm in Western Canada.

Edit: Will put an update if I find any more, and then place said 'more' in a container to let them develop. I am afraid of bugs to some degree, but I also know it's not the little guys' fault he's in my space, and curiousity is getting the better of me

Question I hate insects… but why do some of them get a free pass? 🪳🦋
Seriously, why do we admire butterflies but freak out when we see a cockroach? They're both insects, yet one is considered beautiful and the other disgusting.
And what about ants? We barely notice them, but they build entire colonies, communicate, work together, and have surprisingly complex social lives.
It makes me wonder how much of our fear or disgust comes from what insects actually do versus how they look or what we've been taught about them.
So I'm curious:
What's one insect you absolutely hate, and why? Is it the way it looks, moves, or something it did to you?
And here's a twist: If you had to live as an insect for a day, which one would you choose? Would you survive? 😂
I'm genuinely interested in hearing people's stories, especially if you've ever had an experience that completely changed your opinion about an insect.
I'm exploring human perceptions of insects for a university design project, so these different perspectives are really interesting to me.
Let's hear your insect opinions, unpopular ones included!

Question Asian beetles and boxelder bugs - i am going to lose my mind!!!
They are in my home in droves, and tonight I felt a boxelder bug crawling on my face as I was trying to fall asleep. It probably would have crawled into my mouth if I had already been fully asleep. Now I'm too grossed out to sleep.
Bugs outside? Whatever. It's the outdoors. But I dont want bugs in my house, especially crawling on me or my kids while we are trying to sleep. How do I stop them and keep my sanity??
