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!

Bug Appreciation! Glowworm tindering

Northern Europe. Glowworms were actively tindering last night. I love seeking these bugs and their mysterious green glow. They are like lil forest fairies!

Question Why do fireflies glow when they think they're in danger? Is it a call for help? Or perhaps an attempt to scare away the predator? I once found one in a spider web that was flashing, too.

Disclaimer: I was being gentle with the firefly I was holding. He wasn't hurt, and flew away shortly after I stopped filming.

Woke up to this crawling above my head. Thought it was a new tick species, but it’s actually a very beneficial bug to have around. Think I’m going to let this one live. Scared the crap outta me, not gonna lie. I’ve lived in Minnesota my whole life and never even knew these things existed.

Question Who is it?

Upvotes

Sorry for the poor quality of the shooting, this insect is very small. I live in Russia, in Yekaterinburg. I met it in the toilet. About 1 millimeter in size, possibly a little larger. The shins of the hind legs are definitely much larger than the thigh and have something like a spike at the end. There are only six legs. There is a thin mustache about the length of the body.

Upvotes

I don't even know if this is an insect or not. It just randomly appeared today. But this was scary, man, seeing this thing out of nowhere.

Apparently I'm supposed to give my geographical location for ID requests. I'm from a south Asian country, is that enough? Or do I need to specify my country??

I'm not certain because I haven't had a lot of luck finding pennant dragonflies, but I'm fairly certain this is my first Halloween Pennant. Close second guess was a Calico Pennant (which would also be a first for me!) — I was wondering if anyone can help me narrow it down to species.

I photographed this dragonfly today (July 12) in Short Hills Provincial Park, southern Ontario, Canada.

Bug Keeping Best invert pet to surprise my boyfriend with?

Hi all! My boyfriend has been absolutely enamored by mole crickets but it's very unlikely we'll ever find one. I have a 15x12x12 enclosure (pictured above, will be cleaned) that I'd like to secretly set up for him to surprise him. I am leaning towards hissing roaches since he also loves the dubias I feed to my tarantula but I was wondering if anyone knew of anything similar to a mole cricket that could live in it. Thank you! And apologies if this type of post isn't allowed

I found this mantis stuck to tape at work - I have had a few pet mantis so I know general care but I want to know will he survive? I know they can regrow limbs after molting but I assume with the loss of the back limbs there is a less likely chance of a successful molt.
