Eucalyptus Defoliator Moth with Eggs

Dear sign,
We cannot account for the superstitions you hear in Mexico, but we cannot imaging them pertaining to any real danger.  We believe this moth is in the family Geometridae and it most closely resembles the individuals in the tribe Angeronini which are pictured on BugGuide.
  Perhaps one of our readers will be able to assist in a species identification.

Identification Courtesy of Karl
Hi Daniel and Sign:
It looks like a Eucalyptus Defoliator Moth, Thyrinteina arnobia (Geometridae).  It ranges from Texas and the Caribbean to South America and is considered a major pest of Eucalyptus plantations, particularly in Brazil. I came across this surprisingly similar image on The Caribbean Pest Information Network site. This one is referred to as Tea Moth and the species name is spelled ‘amobia’. If you google ‘Thyrinteina amobia’ you will get quite a few hits and sometimes both spellings are used on the same site, so I don’t quite know what is going on there. Regards.  Karl

As always Karl, your input is greatly appreciated.

I found this today in Wesley Chapel, Fl Nov 2012.
The locus or grass hopper did not move quickly at all like other grass hoppers. He seemed very lethargic.

Obscure Bird Grasshopper with Eggs

Dear Andrea,
We believe we have correctly identified your Grasshopper as the Obscure Bird Grasshopper,
Schistocerca obscura, thanks to the excellent database on BugGuide.  We don’t believe these are the eggs of the Grasshopper.  We believe they are the pupae of some internal parasite, perhaps some species of fly or wasp.  We will do some additional research and seek some outside assistance for this identification as well.

Thank you Daniel!
I couldn’t believe what I saw and knew it was a parasite.. I am excited to hear back from you as to what this parasite it is.
Thank you again,
Andrea Puida

Eric Eaton provides some insight
Wow, that is really strange.  I would bet, however, that those are actually grasshopper eggs, either from another female, or that somehow got oozed out of this very specimen.  She (I’m assuming this is a female), looks pretty damaged anyway, what with missing both hind legs.  Grasshoppers lay eggs in “pods,” whereby the eggs adhere to each other, and that is exactly the case here.  Normally the female lays her eggs under the soil, though.

The grasshopper was just sitting in my friends driveway. It just didn’t appear alert in any way, which is why I thought it was infested with a parasite because it inhibits its neurological way of living /behaviors. This creature was in no way afraid of me and I was very close to it. I took nearly 20 photos of it from every angle. Yes, I’m a medical student and was very intrigued ..
Please tell all involved thank you and I look forward to finding my next mysterious insect for you guys!!!

Hi again Andrea,
Eric’s observations that the Grasshopper looks damaged and your observations that she was not alert point to the possibility that she was somehow severely traumatized which might have caused her to expel her own eggs which then adhered to her body.  This is still an interesting mystery.

so I found the same thing when I was feeding my turtle. Pulled off the legs of a grasshopper to feed him and out came these yellow ovals.  I believe them to be eggs too.

I was in the yard with my camera yesterday and saw a ladybug on some lichen. At first she appeared to be eating it, but that made no sense. Once I repositioned myself, I could see that she was laying ladybug eggs! How cool! I’m sure it isn’t all that uncommon, but I was excited and wanted to share it with other bug people!

Multicolored Asian Lady Beetle Lays Eggs

Hi Brian,
Your photos are very nice and they are a marvelous addition to our archives.  We had hoped that you were lucky enough to have some species of native Lady Beetle laying eggs, but this appears to be the introduced Multicolored Asian Lady Beetle which has become very well established throughout North America.  While they are a beneficial species that feeds on Aphids and other plant pests, it is believed that as their numbers increase, they are crowding out our native species of Lady Beetles which is resulting in decreased species diversity in some areas.  You can read more about the Multicolored Asian Lady Beetle on BugGuide.

Hello there. There are these strange looking bugs that have been seen near where I live (Pacifica and San Bruno California) and I have no idea what they are. Can anyone identify them? I’ve never seen anything like this before!
I’ve seen more than one now, they are very hairy and squishy. They have at least 4 or 6 legs (near their head) and they are always attached to a hairy sack with a hallow black exoskeleton inside and next to what looks like an egg sack. They have wing-like appendages that are small and hairy near their heads.

Flightless Female Western Tussock Moth with Egg Mass

Dear Alexsis,
Your description is perfect and it could not be more accurate.  This is a flightless female Western Tussock Moth,
Orgyia vetusta, and we identified it on the Moth Photographers Group Flightless Females page, but there is even more information on the Moth Photographers Group Tussock Moth Parasitoids page that documents the life history as well as a significant parasitoid predator, a species of Tachinid Fly.  According to Joyce Gross of the University of Berkeley:  “Adult females are wingless. When they emerge from the cocoon (eclosure) they remain upon it and release a pheromone, a sex-attractant that brings males to her. The large antenna of the male is very sensitive to the species-specific pheromone and any males downwind of the female will quickly follow the scent to her location.”  There is also a very nice photo on BugGuide of a newly emerged female.  You can see photos of the caterpillars of the Western Tussock Moth in our archives.

Update from November 22
Now that I have viewed the website I have realized that I have been seeing those western tussock moth caterpillars my whole life and I never would have guessed they would turn into that moth! That is truly amazing. Here is a photo that I took of the caterpillar a few months ago. Thank you so much for your response!

Western Tussock Moth Caterpillar

Hi Alexsis,
More than a week has passes since you submitted the caterpillar photo, but we were away for Thanksgiving, and there is way more mail in our inbox than we can read.  We are updating the posting with your new photo.

Found this on the side of my house and not sure what it is. I’m thinking it’s a Praying Mantis Ootheca but am not sure.

Mantis Ootheca

Hi Christine,
You are correct.  This is the ootheca or egg case of a Preying Mantis.

Good morning, Bugman! I took some photos this morning of some eggs I found on a tarp hanging from the side of our house (the joy of renovations!). We live in the Midwest, not near any bodies of water, and fall weather has been setting in lately. Any ideas on what hatched on the side of my house? (My thumbnail included for scale.)

Unknown Eggs

Dear Laura,
We are practically hypnotized by the subtle pattern of light, shadow, color and texture in this lovely photograph.  Eggs can be very difficult to identify with certainty, especially eggs that were not laid on a food source.  Our first guess might be some Hemipteran, like a Stink Bug, and our second choice is some type of Moth Egg, like a Tiger Moth.  Either way, we don’t believe the hatchlings will infest your home.

Hi Daniel,
Thank you so much for your time and sweet compliments on my photos!  *^_^*
Knowing my luck, it was probably a Stink Bug, hehe.  But our cats do enjoy alerting us to the wide variety of surprisingly diverse moth population, so I would not rule those out.  I’m very glad to hear that the likely bugs are the brave outdoorsy types, not the codependent infesting sorts!  ^_^
Thanks again!
