Subject: What’s this Hopper on my Cannabis?

Subject:  Hi Bugman,
As my Cannabis plants grow larger, I’ve noticed that many of the plants have predators on them.  In addition to the Mantid I submitted earlier this year, I am happy to report that four of my plants have mantids on them and several have Green Lynx Spiders as well.  Can you please identify the hopping insect that I have found on my plants this year.  One of the images of the Green Lynx Spiders I am sending has it eating an immature hopping insect, though it is difficult to see.  The other image is of a winged adult.
Thanks

Green Lynx Spider eats (presumably) Glassy-Winged Sharpshooter nymph

Dear Constant Gardener,
Thanks so much for keeping our readers informed about your thriving
Cannabis ecosystem.  The adult hopping insect is a Glassy-Winged Sharpshooter, and according to BugGuide:  “The biggest problem is that it can spread the disease-causing bacterium Xylella fastidiosa.  The most important biocontrols are egg-parasite wasps in the genus Gonatocerus. Spiders, assassin bugs, and praying mantis prey on the mobile forms.”  Several years ago, we received a report of Glassy-Winged Sharpshooters, Homalodisca vitripennis, on marijuana.  According to the University of California Integrated Pest Management Program site:  “The glassy-winged sharpshooter is found in many habitats, including agricultural crops, urban landscapes, native woodlands, and riparian vegetation. It feeds on hundreds of plant species across dozens of plant families. Hosts include numerous common woody plants as well as annual and perennial herbaceous plants. It is common to find this insect on acacia, avocado, eucalyptus, citrus, crepe myrtle, heavenly bamboo, grape, photinia, pittosporum, hibiscus, periwinkle, xylosma, some roses, and many others. Host preference changes throughout the year, depending on the availability and nutritional value of host plants. Some hosts are preferred for feeding while others are preferred for reproduction. Irrigation level and fertilizer additions can also impact the attractiveness of hosts for sharpshooters.”  There is no mention of Cannabis.  We presume the nymph being eaten by the Green Lynx Spider is a member of the same species.

Buffalo Treehopper nymph

This spiny guy is a Treehopper nymph, and based on this Jungle Dragon posting and this BugGuide posting, we believe it is a Buffalo Treehopper in the genus Stictocephala.  Treehoppers and Planthoppers have mouths designed to pierce and suck fluids, and they rob the plant upon which they are feeding of valuable fluids.  A single individual might not cause much damage, but when they are feeding in groups, significant damage might occur.  We would not consider this Buffalo Treehopper nymph to be a beneficial species on your marijuana plant.  According to the University of Wisconsin Milwaukee:  “In their adult and immature stages, buffalo treehoppers feed on plant sap that they get by puncturing the stems of woody and non-woody plants with their strong “beaks” (and they can do minor damage to both in the process). They may begin their lives on woody plants, where Mom uses her sharp ovipositor to make shallow slits in twigs and to deposit her eggs. When the eggs hatch, the nymphs find their way to more succulent, herbaceous vegetation.”

Planthoppers

Dear Moises,
We believe these are Planthoppers in the family Fulgoridae, and though they bear a superficial resemblance to the invasive Spotted Lanternflies, they do not look like the same species.  We have not been able to find any visual matches online, so we cannot provide you with a species name.  Perhaps one of our readers will have more luck than we have had at an identification.

Your letter to the bugman:  Hi Daniel,
Hoping you can id this interesting little insect.  It looks to me like some type of planthopper maybe, although I’ve never seen one in my garden before today.  Length approximately 1/2 inch and it wasn’t moving much.  I plucked the flower it was on to get some better shots, expecting that it might fly, but it just stayed in place.  Hope these shots are enough to identify it.

Speckled Sharpshooter

Hi Deborah,
You are correct that this is a Planthopper, more specifically, a Sharpshooter.  Planthoppers are insects that feed by sucking fluids from plants, and some species are known to spread viruses to plants, so they are generally not too welcome in the garden.  We quickly identified your Speckled Sharpshooter,
Paraulacizes irrorata, thanks to images posted to BugGuide.  According to BugGuide food plants include:  “Asteraceae: Cirsium altissimum (tall thistle), Cirsium sp., Conyza canadensis (horseweed), Lactuca serriola (prickly lettuce), Silphium integrifolium (wholeleaf rosinweed); Poaceae: Elymus virginicus (Virginia wild rye), Sorghum sp. (cultivated sorghum).”

Thank you for the quick id!  I never mind having planthoppers in my garden, so he/she is welcome to hang out.

Spotted Lanternfly Nymph

Dear Sandy,
We regret that we bear bad news.  This is an immature Spotted Lanternfly,
Lycorma delicatula, an invasive exotic species from Asia that is spreading in and beyond Pennsylvania since its recent introduction in 2014.  According to BugGuide:  “Native to China, India, Japan and Vietnam; invasive in Korea and in our area(1). Currently (2018) known from 6 counties in PA; also found in DE, NY, VA.” 

Thank you for this information.  A neighbor had to take down a tree last summer from these pests.  They were all over the area. I had called a hotline number and they were aware they were in our area. Not sure what is being done. I kill them when I see one.
Thanks again.

Last 2 for a while, if you don’t mind.
First one is, I suspect, a Net winged beetle of the Lycidae family.
The second, I have to admit, has me totally stumped.  It doesn’t appear to be a True Bug, moth or butterfly and cannot find any images of beetles even remotely similar.
Your help would be very gratefully received.

Red and Black Froghopper

Dear Fof,
We quickly identified your Red and Black Froghopper,
Cercopis vulnerata, thanks to Alamy and the British Bugs site where it states:  “A truly unmistakable species, and one of our largest homopterans. The nymphs are rarely seen, as they feed on underground roots.”  According to iNaturalist:  “This species is present in most of Europe (Albania, Austria, Belgium, Bulgaria, Croatia, Czech Republic, France, Greece, Spain, the former Yugoslavia, Moldova, the Netherlands, Norway, Poland, Romania, Russia, Slovakia, Slovenia, Switzerland, Hungary, Great Britain and Italy).”  As with other Hemipterans that have mouths designed to pierce and suck, they might cause wilting of tender stems if they are plentiful, but a greater problem is the spreading of pathogens from plant to plant while they feed, based on what we found on EuroFresh.  We never heard back from you after we identified your Common Picturewing from Vietnam.
