Your letter to the bugman:  Hello sir,
This weirdo cocoon(?) is on our Silver Sheen Pittosporum tree. We’ve been puzzled about it for a few months now. I woke up this morning thinking about it, I’m concerned that it might be harmful to the tree, as four of these trees have mysteriously died in the past year.  Is this the culprit?
Thank you for your time!
How you want your letter signed:  No, thank you.

Mantis Ootheca

This is the ootheca or egg case of a Preying Mantis and it is not responsible for the death of your trees.  Mantids are predators that are often used by organic gardeners to control insect pests without the use of pesticides.

Thank you, Daniel. We didn’t hear from you guys, so we brought it inside. We put it in a terrarium and about three weeks ago, 20 aliens popped out. They were adorable.
My question now, are these predators a threat to the Monarch and Gulf Fritillary caterpillars that we raise?
Thank you,
Mike

Hi Mike,
Your original request arrived when our editorial staff was on holiday and we never seem to catch up on requests when we are away from the office.  We do not believe native California Mantids are a threat to either your Monarch or Gulf Fritillary Caterpillars, but Mantids will eat pollinating insects including Bees.

Subject:  Bug or fossil?

Your letter to the bugman:  I have no idea what this is. It was found in Southwest Washington state and is the second one we found. The first one was a couple months ago this one was just found a couple days ago (that would be early February). At first I thought it was a fossil but now I’m not so sure. If you can’t tell me what it is do you know who I might ask that’s local to Southwest Washington?

Mantis Ootheca

Dear M.c.hlousek,
This is the ootheca or egg case of a Preying Mantis, but we cannot say for certain if it is a native species or a species introduced for agricultural purposes.  When conditions are correct, you should expect young mantids to hatch and begin hunting.

Your letter to the bugman:  I noticed this formation on my door frame. I wold like to know what it is. If it’s a pest I need too kill it with fire. But if its a harmless critter i would like to keep and study it.

Anglewing Katydid Eggs

Dear Anthony,
These are the eggs of an Anglewing Katydid which you can verify by comparing your image to this BugGuide image.  Adult Anglewing Katydids resemble large green grasshoppers, but with very long antennae, and they have wings that help camouflage them among the deciduous leaves that they feed upon.  Anglewing Katydids are solitary feeders and they do not harm trees because of the few leaves they eat.  Males call to the females and the “song” of a Katydid is a welcome summer night sound.

Saw this during a recent hike in Central FL, Gulf Coast. It looks distinctive, but I’m stumped…
Thanks in advance, and happy new year!

Mantis Ootheca

After a bit more Googling and brainstorming, I located some photos of very similar looking structures that had been ID’d as some type of mantis egg case. Am I in the right track?

Dear Frank
Your googling provided you with the correct information.  This is a Mantis ootheca or egg case, and it looks to be that of a native species, probably the ootheca of a Carolina Mantis which is pictured on the Bug of the Week site.  The ootheca of a California Mantis looks quite similar.

Vapourer Eggs

Dear Delfina,
These are the eggs of The Vapourer,
Orgyia antiqua, a species we found on Nature Spot where it states:  “The female lays her eggs on what remains of the pupal cocoon, which then overwinter. When hatched, the very hairy caterpillars feed on a range of deciduous trees and shrubs.”

Subject:  Argiope egg cases, black widow?

The argiope I sent a photo of in March disappeared (died/was eaten?) a week or two ago. I thought you might want to see the egg cases she left for next spring.
I also include a photo of what I believe is a black widow. (I couldn’t get a shot of the side with the red on it.)

Egg Sacs of a Golden Orbweaver

Dear Laurel,
We did receive an image of a Golden Orbweaver from you in August.  Thanks for sending images of her egg sacs.  Orbweavers are short-lived spiders, living only a single season.  Your other spider does appear to be a Widow. 

Sorry about the date mix-up. I first saw the spider in March.
