Gardeners are frequent contributors to our site because of concerns they have differentiating beneficial insects from injurious species. With more and more gardeners attempting to cultivate Cannabis, we started noticing more identification requests from growers. We hope we are offering a public service by responding to our readers’ questions without sensationalizing or taking sides surrounding the legalization of marijuana.

Dear Mr. Bug,
There is a lovely green spider living on my woody plant. My boyfriend insists that this spider is just guarding the plant from other, more nefarious bugs. It is quite a beautiful spider and has black hairs on its legs. What is it? And will this spider eat my stigmas?

Green Lynx Spider

Dear Lady Nugs,
Goodness gracious, Mt. Washington seems to be a fertile environment for growing woody plants.  Your boyfriend is correct.  Spiders are predatory and not phytophagous, so your plants are safe.  This is a Green Lynx Spider, and the shape of the pedipalps indicates this is a female.  We did need to brush up on our botany regarding the “stigma”, so we headed to Encyclopaedia Britannica to rediscover that “The gynoecium, or female parts of the flower, comprise the pistils, each of which consists of an ovary, with an upright extension, the style, on the top of which rests the stigma, the pollen-receptive surface.”  Your images are gorgeous, and the detail is incredible.  It is our experience that Green Lynx Spiders gravitate toward plants where they will be well camouflaged.  Your Green Lynx Spider blends in perfectly with the inforescence also visible in the image.

Dear Bugman,
I try to keep abreast of what I am finding on my woody plants, and you have provided such excellent information in the past.  Please help me identify this metallic green insect.  It moved about very warily, and getting a photo was not easy.  Thanks for any assistance you are able to provide.

Long Legged Fly

Dear Constant Gardener,
This is a Long Legged Fly in the family Dolichopodidae, and based on the Natural History of Orange County site, we believe it is
Condylostylus longicornis.  The species is also pictured on BugGuide where it states the range is:  “California; North Carolina to Paraguay; Polyensia. Possibly the most widespread species of the genus.”  Of the family, BugGuide indicates:  “Mouthparts are for piercing (with a short proboscis). Adults and larvae prey on small insects.”  This is a beneficial predator that will help keep your plants free of Aphids and other small insects that are injurious to garden plants.

hello I am growing legal recreational cannabis in Portland Oregon and have been very careful to keep an eye on the plants for various caterpillar larvae and other pests, this morning I noticed something I’m fairly sure was not there yesterday and I could only find one example of this they are neatly clustered on the bottom of one leaf towards the top of the plant. Nice little perfectly round white eggs. Attached is a photo. I’m thinking Moth of some kind maybe? Biggest goal is to prevent these from investing my few plants. Any advice would b greatly appreciated. Thanks for your time.

Probably Moth Eggs on Cannabis Leaflet

Dear Casey,
Eggs can be very difficult to correctly identify, but we do agree with you that these appear to be Moth Eggs, but an exact identification my be impossible.  You can try isolating these eggs until they hatch, and then try raising them on fresh leaves until they get large enough to more accurately identify.  According to I Love Growing Marijuana:  “Caterpillars love marijuana plants! Corn Borer and Hemp Borer are the two most destructive caterpillars.”  Two sites with advice we would question are Alchimia because it pictures a Spurge Hawkmoth Caterpillar,
Hyles euphorbiae, NOT on Cannabis (see BugGuide for verification) and  Royal Queen Seeds because it pictures a Black Swallowtail Caterpillar that feeds on plants in the carrot family, not on hemp.  Dinafem advises:  “Look out for butterflies: If you see any butterflies resting on your plants, try to chase them away because they could be laying eggs. If you have seen butterflies on your plants, you should start to be suspicious and check for caterpillars.”  That sounds like ridiculous advice to us as we know of no butterflies with caterpillars that feed on Cannabis.  We would recommend keeping a close eye on your plants.  We recently created a new tag on our site What’s on my Woody Plant? so that we can address insects and other creatures found on Cannabis, and we hope to build this tag into a usable resource for growers so that they can distinguish between beneficial and problematic creatures they find on their crop.
P.S.  If you decide to try to hatch these eggs, please send a followup image or two our way.

Thank u so much for responding, I seriously appreciate it! I’ll do just that and I am going to grab a friend, sit down and give them a very thorough examination top to bottom to make sure they aren’t trying to start a city. Again thanks a ton for the help. Have a great day!

Just as the sun was setting, I discovered two Green Lynx Spiders where there used to be one.  Do you think they will mate?

Two Male Green Lynx Spiders

Dear Constant Gardener,
While the pedipalps are not readily visible, it appears both of your individuals are males.  If this plant provides good hunting, there might be a “survival of the fittest” scenario that plays out here with one Green Lynx getting eaten by the other, or perhaps one will just move on.  Since Green Lynx Spiders do not build webs, they tend to move around a bit, though female Green Lynx Spiders will remain in one location to raise young.  At any rate, having these Green Lynx Spiders on your plants will help to keep unwanted, plant feeding species at bay.

Dear What’s That Bug?
I spotted a crazy bug eating a spider on my woody plant. I know this isn’t the best picture (attached), it was at dusk and I was using the light of a headlamp and an iPhone, but hopefully you can decipher what’s happening.

Immature Orthopteran eats Spider on Woody Plant

Dear Max Yield,
This is a Longhorned Orthopteran nymph from the suborder Ensifera, and having it living on your woody plant might not be the best long term plan.  You don’t want spiders getting eaten as they are predatory and beneficial, and the Orthopteran is likely an omnivore that will eventually eat leaves and possibly even buds.  We suspect this is some species of Katydid, and young nymphs like this can be difficult to correctly identify to the species level. In our own garden, we allow Katydids to eat rose blossoms, but you might not want anything to reduce your maximum yield.  We enjoy the sound of the Katydids at night in our garden, so we would not harm this very young, possibly second instar nymph, but we would not think twice about relocating it elsewhere in the garden as they are not especially particular about what plants they eat.  Since creating our What’s on my Woody Plant? tag, we have gotten some flack from our Facebook followers.  On August 8, Nancy Barlow wrote “Get some new material…. not funny any longer….”  Within an hour and a half, Amy Holder wrote:  “Yeah im over the woody plant coverage as well. There are other sites dude can post and show off all his weed. Gtfo.”  We didn’t know that “get the fuck out” had an acronym until we looked it up.  We can’t believe that people who follow us think that being funny is our prime objective or that we are interested in showing off weed.  We attempt to identify insects and things that crawl, and we occasionally devote tags to specific groups of plants with robust Arthropod populations, including the Milkweed Meadow and the Goldenrod Meadow.  Furthermore, we believe in the malleability of the English language, and using regional terms has a certain charm.  We would never disparage anyone who used the terms herb or mota.

Hello bugman!
I saw this butterfly in Montana back in July and haven’t been able to “pin” down what type it is. The color brings up too wide of a search result, and most of them more black and orange than white. I’ve seen swallowtails with similar coloring, but this doesn’t seem to be a swallowtail by shape. Birds are usually my target, but I do try to ID the butterflies as well, and this one is flummoxing me!
Thank you!

Gorgeous image of a Weidemeyer’s Admiral

OK Tina,
Please forgive us for bypassing your question to tell you this is just about the most beautiful image we have seen in a long time of a butterfly.  With such shallow depth of field, you were quite lucky this perfect specimen decided to pose with its wings parallel to the film plane.  As you can see by this BugGuide posting, this is a Weidemeyer’s Admiral,
Limenitis weidemeyerii.  What was the environment like?  According to BugGuide:  “Found around wet places where its host plants grow” and “Larvae feed on Poplar (Populus spp.), Willow (Salix spp.) and perhaps other woody plants.”  Woody plants have sparked quite a dialog on our site and its Facebook page of late. 

Thank you for the glowing compliment! I blush! I think my experience trying to capture birds has helped with be more patient with setting up a butterfly shot, but I always consider myself lucky either way. I have a lot of pictures of empty branches!
This is where I found it, and your comments about environment are spot on. There is a creek that runs through the area, and the woods are fairly old and dense. A lot of pine, but also a lot of shrubs because of the creek, such as willow.
I’ve stopped here twice going to and from vacation spots in Montana. It’s a good spot, but small, to find a thrushes, flycatchers and a yellow warbler or two while you stretch your legs a bit.
Thank you for the ID, I would’ve never ever figured out the type from the underside of the wings, compared to the pictures of the topside I see with the name look up! Even worse, I have what I think is a White Admiral from 2012, and didn’t make the connection. There was also another butterfly from the same place and date I haven’t had the time to ID either, though it looks like checkerspot or frittilary. Attached, just for fun.
I started bird watching in 2013, when I got sick, and 10 months later had brain surgery (long story) but it’s taken us some amazing places, and we love to see all the wildlife along the way. Below is a link to my better shots from as far back as 2010, and if you click on the “i” it tells you when, what and where, though please don’t think you have to ID them. I am pretty OCD about IDing birds and trying to not let it get too deep into other things I see, haha! Anyway, just enjoy if you have the time. And yes, you helped me ID the Police Car moth a couple of years ago! 🙂
