Bulbs have a habit of sulking when moved.  The Eremurus have a minimal tunic and I'd guest prone to drying.

The spotted lantern fly has three to four instars before you see the adult with wings.

I picked up a small infrared camera lens that plugs into my iPhone.

I agree with you completely.

I have protected the trees on my property.  Doesn't help the trees in local parks or those planted on the streets.

They are all at risk.

I think it's just as easy to spray BT and DDT over a large area.

I have some doubts, myself about the damage created by DDT.

There are many other much safer ways to control pests.

I use many here without resorting to dangerous chemicals.

There's a new one on the market based on a peptide found in an Australian spider venom.

Most people lack the knowledge or interest in looking for safer methods.

It's always easier to take the most available option.

They seem to have wide likes here in NE NJ.

I've found them on pears, apples, plums,grapes Raspberries and most of the street trees around these parts.

I suspect they will have a large impact on native trees.

Based on my casual observations it eats just about everything.

Has some favorites like Ailanthus altissima and Evodias.

Found on grapes, maples, apples, raspberries.

Looks like the eggs fall to the ground in spring and the nymphs climb trees to feed on softer plants structures like tender shoots and stems.

The last instar prior  to becoming the moth is brightly colored red and black.

Couple of better photos with a macro lens. This is the first instar soon  after hatching .  The nymphs rushing up into the catch jar where a pheromone lure is placed.

They are highly reproductive in our environment.

Luckily only one generation per season
