Your letter to the bugman:  While out to lay pavers in our yard we got to watch a fascinating insect we’d never seen before. We watched for some time as it dug in our soft dirt, buzzing in the hole, moving rocks (sometimes as large as it was!) and at one point it unearthed a grub of sorts! Biting it behind the head it held in… it didn’t appear to sting it, and eventually the grub ceased to move. For an hour we watched as our friend dig holes, and then moved on to another spot. On one hole we watched her start to fill it back in, going in to buzz excitedly, then back to digging. I have a couple of videos too, if you’re interested.

Thread-Waisted Wasp with Cutworm Prey

Dear Kristi,
This is a Thread-Waisted Wasp in the family Specidae, and the prey is a Cutworm.  The Wasp will not eat the Caterpillar.  Rather, the female Wasp has paralyzed the Caterpillar which it will bury and the paralyzed Caterpillar will provide food for the developing Wasp larva which will feed on the helpless, but living Caterpillar.  We believe we have correctly identified your Wasp as
Podalonia argentifrons thanks to images posted to BugGuide.  According to BugGuide:  “Larvae are provisioned with caterpillars exclusively from the family Noctuidae.”

Your letter to the bugman:  Dear Bugman,
Exactly one month ago, I sent in images of a Green Lynx Spider that laid an egg sac on one of my medical marijuana plants, and this morning I noticed her eating a Budworm, and her brood has hatched.  I thought they would hatch in the spring.  What gives?

Green Lynx Spider eats a Budworm while guarding brood.

Dear Constant Gardener,
Thanks for keeping our readership up to date on the mundane dramas in your garden.  Daniel has always thought that the eggs of Green Lynx Spiders would hatch in the spring.  Lower beasts are much more attuned to their environments than are most humans, and perhaps global warming is affecting the hatching cycle of Green Lynx Spiders.  According to the Orlando Sentinel:  “A green lynx spider’s egg sac is much easier to spot than the spider itself. The sac is a slightly bumpy, sand-colored container housing up to 600 bright orange eggs that will hatch within 11 to 16 days. The sac is about an inch diameter with one flat side and one rounded. After its construction is complete, the female spider surrounds the sac with a sketchy tent of randomly woven silky threads. She then protects it further by clutching it with her legs as she hangs upside down.”

Subject:  I found evidence of a Budworm on My Woody Plant

Your letter to the bugman: Dear Bugman,
I was inspecting the nugs of My Woody Plant when I discovered evidence of Budworms on two colas.  I’ve learned so much since I submitted an image of a Budworm two years ago.  I immediately harvested both and set up a three bowl wash of first hydrogen peroxide in water, second lemon juice & baking soda in water, and finally a water rinse.  While trimming the cola, I discovered a silken chamber with a .3 inch bronze-backed Jumping Spider that I carried back to the garden to the plant I just trimmed, talking to it as it jumped from one hand to the next, back and forth.  Sorry, I didn’t have a camera at the time, so no photo of the spider.  I finished cutting out all the caterpillar fouled portions of two buds, but I never found the caterpillar.  Do you think the caterpillar moved from one cola to the next where it encountered the lair of the Jumping Spider that promptly ate it?  I didn’t want to count on predators to control these dreaded Budworms, so I followed the advice of Mel Frank and promptly sprayed my plants with Bt, a naturally occurring bacteria that causes the caterpillars to stop eating so they eventually die, and it is not a pesticide so it doesn’t harm my predators, like spiders and mantids.

Budworm damage on Cannabis

Dear Constant Gardener,
We will probably catch some flack from some Facebook followers for highlighting another Cannabis posting.  Thank you for sharing your organic Caterpillar prevention strategy as well as your saving a tainted crop strategy.  We found information on The Cannabis Grower that states the Budworm will “burrow into your buds and eat them from the inside. You’ll have no idea they’re even there until you see a bud that looks a little off…one leaf is dying, or the bud looks dried out, somewhat similar to the symptoms of bud rot. If you see this, you must inspect the bud. Take the leaf or bud and pull it away from the plant until you can see all around it. Look for sand-grain sized balls that are black or brown. That’s caterpillar poop, and you have a problem. The good news is that you can usually find the worm by following the poop around the buds until you find the worm or the hole he’s in. The bad news is you MUST find that worm, otherwise he’ll just keep eating and eating into your buds.”  Regarding the possibility that the Jumping Spider ate the Budworm, we suppose that is entirely possible, especially since you did not fine the culprit.

Your letter to the bugman:  We saw this caterpillar this morning in our yard.  We simply can’t find any one similar in trying to identify what it is.

Paddle Caterpillar

Dear Katie,
The Paddle Caterpillar,
Acronicta funeralis, is surely a distinctive species.  According to BugGuide:  “larvae feed on leaves of alder, apple, birch, blueberry/huckleberry (Vaccinium spp.), cottonwood, dogwood, elm, hazel, hickory, maple, oak, willow.”

Thank you so much!!  My daughter will be ecstatic to know we got a reply.  We truly appreciate it!
Katie

Your letter to the bugman:  I was hiking and picked up a stick, and underneath I saw a caterpillar-looking bug, presumably hiding its head in a hole in the stick (possibly snacking on the wood?). I tried looking up what kind of caterpillar it was, but can’t find a similar picture with any of my google searches. Please help me learn what kind of bug I found, it looks so cool! Thanks! (Please see picture attached.)

Beautiful Wood Nymph Caterpillar

Dear Andi,
Because we began our search with a false lead, our identification of this Beautiful Wood Nymph caterpillar,
Eudryas grata, took some additional time.  Our wrong lead began with locating this image online and the associated site, Beautiful Now, where it is associated with the following caption: “We love the beautiful blackberry and flower petal-eating Blackberry Looper (Chlorochlamys chloroleucaria) patterned with both stripes and polka dots, in bold shades of orange, white, and black.”  The Blackberry Looper Caterpillars on BugGuide are a very different Caterpillar.  Additional searching led us to this BugGuide image of the Beautiful Wood Nymph Caterpillar.  According to BugGuide:  “Larvae feed on leaves of several shrubs, vines: Ampelopsis, Buttonbush, grape, hops, Virginia Creeper.”  We wouldn’t rule out that this might be the related Pearly Wood Nymph Caterpillar, Eudryas unio, which is also pictured on BugGuide.  We don’t know why it was crawling into the hole in the stick.
