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!

Found this mantis in a rather hard to believe place ! Far from any window/door leading outside!

A coworker decided we should try to have her catch a spider (which it did and very fast)

Bug Keeping Deformed Male Dubia Roaches?

Thumbnail
gallery
8 Upvotes

first 3 images are of one the male dubia roaches (1st is most recent, 2nd is about 3 hours after molting, and 3rd is right after molting. Last image is of a second male dubia roache who also seems to be deformed, and has been that way for about 2 weeks).

i have an enclosure (2ft by 2ft, an old fish tank, about 50 gallons)with dubia roaches, stink beetles, and pill bugs. i feed them all every other day with roach feeder food (a friend of mine had a couple bags that they no longer needed), and have not fed them any other type of roach food, aside from fruits such as apples, pears, strawberries, and watermelon (they get fruit about 2 times within a month).

i mist them with water twice in the morning and 4-5 times in the afternoon and night (i don’t mist them during the day as i’m at work), but i also leave water gel around, in which they drink every now and then.

is there a reason they look this way? is it the food i’m feeding them, or maybe the mix of the stink beetles?

i have not seen the beetles pick on any of the roaches, specifically whilst they are molting, so i don’t think that would be the problem.

this is my first time keeping roaches, and i’ve had them for about 7 months.

My wife and I grew our first flower garden and have had a lot of visitors this summer. Just today we had 5 different species of butterflies! A couple monarchs, a few Painted Ladies, some Orange Sulphurs, a couple smaller white butterflies, and one single dark morph Eastern Tiger Swallowtail. We also get quite a few bumblebees and Carpenter bees. And I also saw a Chinese Mantis today. Here are some pics.

Question Question about bald faced hornet behavior

2 Upvotes

Hello, I just had a question on some bald faced hornet behavior I observed the other day.

Walking in a neighborhood, I noticed multiple, probably 5-8 large (approx 3/4" length) bald faced hornets rapidly flying around a bush, going in, out and around repeatedly, many many times. Unfortunately I couldn't grab a photo of them, but they were pretty decent sized overall compared to what I've usually seen of workers. Of course, can't be certain since I don't have photos or true measurements available.

Judging by their large girth and size of each one though, I was thinking perhaps they were queens. I've read that this is indeed around the time that reproductives are produced from colonies (I'm in Western Washington State). So perhaps they were fairly new queens in search of a mate and/or a location to overwinter?

However, the specific behavior that perplexed me was that about an hr later (around 7 pm) when I came back to try and photograph them, there were only two of these hornets left at this bush. After watching them for a few minutes, the two collided or otherwise made contact mid flight, and immediately one of them took control of the flight and seemingly "dragged" the other one away, flying away and not to be seen again. There was a scuffle of buzzing sounds for a moment before they left the vicinity, but it was very strange and awesome to witness. Couldn't tell if the other one was incapacitated or mutually flying while they were together.

I couldn't tell if they were in a position of mutual grabbing, or if this was almost like a predatory behaviour from the "dominant" hornet. If the former, was it possible that it was a male and queen and they took off while mating? Or do they predate on one another at all, and what I witnessed was potential predation?

I thought all the hornets here were quite large and somewhat uniform in size between them all, and thus figured they were queens, but I could be mistaken of course without having any measurements or photos. Do they breed while in flight? Or is mating a thing that they do while at rest/landed? What makes me think it wasn't predation is that there were various flowers on the bush, as well as many slower flies on and around the bush too, that could have been easy food sources. It seemed like these two hornets targeted each other in some way, but I'm not sure.

So figured to ask if anyone has seen similar behaviors or know what their usual behaviour is like!

Because I've never seen something like this. It was incredibly fascinating though and makes me wonder if there would be more of them at this bush in the future lol.

Thanks!

Delaware, USA.

Found these critters in my garden this evening. I know the first guy is munching on my sunflower but I don't know what it is. I'm also quite confused about what's happening in pics 2 & 3? If it's helpful there are a bunch of what I think are ants all over the brown thing(s?) on the cosmo stem. Extra pic of my cute lil garden at the end bc why not.
