When the JB's arrived here 15 years ago that is what happened. For 2-3 years there were no summer blooms or fruits. I was ready to give up on crapes. I couldn't imagine what the vineyards and orchards were going through. After the initial infestation the population stabilized and they are now pretty much a nuisance most years. Next on the horizon for us is the gypsy moth, and they are more than a nuisance. Oh and almost forgot EAB and ALB and HWA and and...

Strange, I was just about to start a thread about JBs. After years of increasing damage, there's not a single one this year! I keep thinking they are delayed, but obviously at this point, they just aren't coming at all.

I've seen adult EAB in person for the first time last month. A large Ash has severe dieback near the lot tree line then there is another one pretty close that is quite large. Say good bye to its beautiful golden yellow fall color.

David,

what type of soil do you have? If I go 15 miles south to clay soil land the Lindens look fine to me. I've seen JBs here and there over 10+ years so its odd to see such a significant population spike this year. It was the same for May/June Beetles.

I set up a game with my younger daughters to go on a beetle hunt. We collect close to a 100 every night for 3 weeks now. I was tempted to spray at a higher level but there are too many other insects pollinating.

Loamy soil. I have not done anything to control them, so it's a real mystery they are gone this year. But a welcome one, they really wreck havoc with certain plants like Hydrangea sargentiana.

This year theybarw bad here, I blame the mild winter.

Just a couple here in west MD this summer. Populations seem to cycle up & down -- I remember much more severe infestations yrs ago.

Yeah, I bet its based on generations and then timing for wetness/dryness.

I'll get a few pics of the trees. I just drove by a couple Buckeyes, says 20' tall, and the entire canopy is brown.
