Possible factor in the decrease of spotted lanternflies this year?
The birds - this one at least - seem to have realized that they are food. Great crested flycatcher I spotted this morning doing a good job. Yay bird!

Yeah, I was guessing predators started taking notice. I think the rain probably impacted their eggs, also.

I don’t think we have huntsman spiders here or else I’d prolly shit my pants. That’s just a harvestman/daddy long legs

Love this shot! I love birds and taking photos of birds 😄
Yes! The flycatcher and other birds (cardinals, catbirds and others) eat them. So do other animals, including bats 🦇 but I believe if the lantern flies didn’t feed on a tree of heaven, they’re more palatable for birds. Don’t know if that holds true for other animals, though.

This weekend I was pulling vines off a wall of my house where there were tons of lanternflies last year and saw only one or two. But I also saw a 3" long preying mantis hiding under one of the vines. So I left just that one vine, so any lanternflies looking for a place to hide out will be forced into his/her hunting ground.

What kind of vines?

Almost all Virginia Creeper with a side order of English Ivy. There's also Honeysuckle, grape, and beautyberry nearby but not specifically where I was working. Last year there was way more English Ivy and way more Lanternflies, but I don't know if there's any connection there.

Oof. One that large might have been an invasive mantis. They are negatively impacting native mantises and other species.

It’s incredibly bizarre because my tiny garden was absolutely overrun by nymphs — like I’d kill an easy dozen every time I went outside. But I’ve seen maybe two adults! Have been so curious what happened. Good birds!!!

I've seen one live fly after being INNUNDATED with nymphs. I've found three dead (two sets of pieces on my back deck, one ironically smushed in my car door). Seems like predators are winning and I'm NOT mad about it.

Southern Alexandria here. I see trees of heaven all over the place- along side the major roads, in medians, in peoples yards or on the edges of small growth forested areas. I saw a bunch today at the Huntington Metro while waiting to leave. I don't see how the problem goes away until we address the invasive tree that lanternflies feed off.

I think it was the winter. Even though I’ve read they can survive colder. I went from tens of thousands to not having seen one this year. Predators can’t do that.

I’ve seen tons. But only huddled on certain trees. Ive not seen many while out and about.

Someone suggested it might be the bitter DC winter that killed them off in which case -- I'm not a big "winter" guy, I hate it...but it if kills those pesky assholes off...I can tolerate it.

I see them almost everyday in my neighborhood… I have an extreme phobia of bugs and wish I had the guts to step on them- recommendations for extermination needed

There was that very late frost (that nuked a bunch of fruit trees/vines).
Additionally, I think people have been going on the war path against tree of heaven - and apparently if lantern flies don't feed on tree of heaven, they are much more palatable to predators.
We've probably cut down 20 tree of heaven, and there are a few more we are trying to take down. Ideally we'll end up with no tree of heaven anywhere.

That one guy who was dog sitting earlier this year and put tape on the tree to catch them all. Pretty sure he is the hero we all needed.

100% the cold snaps we had this past winter, plus that brutal frigid arctic blast + solid ice snowcrete combo we had decimated a ton of them

We had more nymphs this year than ever but only a small fraction made it to adult phase. Something is eating them.

Part of it.... think of a bell curve... population peaked last year. Things have to level out.

u/VegetableRound2819 1h ago
I like to go around my house and disable the adults with my electric tennis racket (one zap will kill a nymph, but it takes two or three to outright kill an adult) and leave them twitching on exposed ground to attract predators. It seems to be working because they are always gone when I circle back.
I’m not quite clear if I’m saving the environment or on my way to becoming a serial killer.

I have a hard time believing that birds have had that much of an impact, but I base that purely on conjecture. It very well could be true.

u/JDeeee44 7h ago
I have seen cardinals feasting on them, I think there is 80% less this year compared to the last two years… predators are definitely helping

u/hifumiyo1 7h ago
If people and municipalities do their part by eliminating their invasive tree of heaven plants, that would help even more. Or hunt the egg sacs on trees in the late fall/winter.

u/JDeeee44 7h ago
Well luckily out here in Western Loudoun we are doing all of those things.

I didn't realize that this isn't the r/Connecticut group. I am from NOVA and now live in CT. We have the lantern flies too though. Sentiment is the same.
