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!

I was wondering do all monarch eggs hatch? I collected what I thought were monarch eggs and check twice a day…some just disappear???? Is this possible? Thank you.

Monarch Egg

Dear Cindy,
If every insect egg that was ever laid eventually hatched and matured, humans would quickly get displaced on the planet.  We don’t know the circumstances of your collection process, or where the eggs are being housed once they are collected.   Are you collecting just the eggs, or the leaves?  How are you keeping the leaves fresh once you collect the eggs?  Why are you not leaving the eggs in place?   Many caterpillars eat the egg shell after hatching, and that provides their first meal.  Though your image does not have the same critical detail as this Learner.Org image of a Monarch Egg, they do appear quite similar.  Regarding eggs just disappearing, it is possible they are falling prey to something. 

Thank you for responding.  I cut off part of the milkweed leaf with the egg and kept them in a pan in the garage.  Yesterday I cut the entire leaf and carefully placed just the leaf stem in a vase of water in the house.  I removed the eggs because the milkweed was covered with ants and other bugs – I was afraid the eggs would be devoured.  We also have a large bird population.

Stink Bug Eggs

Dear Chris,
These are the eggs of a Stink Bug in the family Pentatomidae, but we are not certain of the species.  Here is a BugGuide image for comparison.

Mating Monarch Butterflies

Dear Jeff,
Thank you so much for sending your gorgeous images documenting the complete life cycle of the Monarch butterfly.  It is going to take us a healthy chunk of time to format all your images and set up the posting properly so we are just starting by posting an image of a mating pair of Monarchs.  The male is the individual with the open wings, and the female appears to have been tagged because her hind wings have what appears to be an inked marking.  We can also identify the male, according to BugGuide, because:  “Males have scent-scale patches on hindwings, prominent when wings are open, and just possible to see when wings are folded.”  Over the course of the day, we hope to get all your excellent images added to the posting.

Male Monarch

Hi Daniel,
I don’t have complete life cycles for the rest of the butterflies that have graced our back yard, but I’ll send in what I have.  Regarding the Marine Blue, I can resend them with the other pics.  The ones I sent seemed to have unusual coloring.
By the way, I want to thank you for so graciously accepting my pictures.  It makes me happy to be able to share them.

I took this photo and when I looked more closely I discovered there were eggs in the picture. I don’t know if the eggs are from the beetle or the other bugs that were nearby. I believe this to be a white oak borer.
(I just sent another image and should have mentioned that I don’t think the giant beetle in the photo is a hercules beetle. I hope you have time to take a look at it.)
thanks again

White Oak Borer

Dear Grace,
Thanks for sending in your image of a White Oak Borer.  We do not believe the eggs belong to the Borer.  We believe the eggs are Tiger Moth Eggs.

Can you identify this egg cluster? Found in late May after a somewhat rainy period. On the east side of the fence, our wind typically comes from the west
Looks like Mother Nature has OCD too!

Probably Moth Eggs

Dear Barb,
Eggs can be very difficult to identify.  Our best guess on this is that they are some type of Moth Egg, possibly a Tiger Moth.  We are certain they are not the eggs of a Painted Tiger Moth as it is a western species, but this BugGuide image would also be similar to the eggs of Tiger Moths found in the eastern parts of North America.  We are post-dating your submission to go live to our site later in the month when our editorial staff is out of the office on holiday.

Thanks for the speedy reply, Daniel!!
Was wondering if the eggs would hatch if I scrape some off into a container and keep in similar conditions?
Thanks again !!

Hi Barb,
That might work, but scraping them from the fence might damage them.  We are curious if there is some reason you don’t want to leave them on the fence and just let nature take its course.

Actually, I’d be more apt to leave them, just curious if a couple might hatch successfully but I’ll leave them.  My college entomology days are long past, lol.

Hi again Barb,
By all means, try removing a few.  Tiger Moths often make the egg shell their first meal.  Many Tiger Moth Caterpillars are general feeders that will eat a wide variety of “weed” plants. 

Mother Nature was also fast, I went out there about 3pm yesterday and the eggs were gone.  Lots of weed plants for them to feast on here, we don’t use any lawn chemicals because of the dogs, but the insects have to watch out for our 7 Guinea fowl.
Thanks again for your identification help!!!
