Monarch Chrysalis Christmas Tree

Ed. Note:  We thought this was such a lovely photo and such a marvelous example of a Bug Humanitarian that we are passing on the holiday greetings to our readership regardless of faith or denomination.  As arguably the most intelligent life form on this planet, we humans have a responsibility of stewardship for the environment, including the lower beasts.

My Christmas tree this year
Location:  This is in Jacksonville, Florida, on the banks of the beautiful St Johns River.
December 20, 2011
This is my Christmas tree this year, and I love it.
A late hatching of Monarch caterpillars during a cold snap made me carry many of them inside for protection.  Now they’ve gone into chrysalis form (I have video!).  Obviously, I transferred them from their chosen sites (not always good choices) to a little bonsai tree, where they’ll all have clear “take-off” points.
The black chrysalis (on the right) is about to hatch – they turn black before they break out.
Merry Christmas!

Monarch Chrysalides as holiday ornaments

Dear Lane,
Thank you for the lovely holiday greeting which we are featuring as a post.  We are also tagging you as a Bug Humanitarian because of your rescue intervention.  Could you please provide us with a location for the photo?

Of course!  This is in Jacksonville, Florida, on the banks of the beautiful St Johns River.
I must add a sad but educational note:
These Monarch caterpillars were laid and fed on first-year Mexican milkweed.  But I’ve learned that that species harbors a parasite that kills the caterpillars before they can chrysalize IF they feed on second-year plants.  Mexican milkweed (not native to Florida)  tends to live through the winter so produces second-year plants.  It’s a real threat to Monarchs here.
The sad part is that I had a dozen healthy caterpillars but my plants were eaten up so I went to a friend for foliage and her clippings must have  come from older plants as all the caterpillars that fed on it died.  It was very sad to see healthy caterpillars collapse and die a slow death from the parasites.
I’ll pull up this year’s plants and use native species next year as they do die back in the winter.
Thank you for your fascinating and helpful site.  You do great good for the bugs of the world – and the humans too.
Happy holidays and New Year,
Lane Welch

Thanks for the information on the milkweed dilemma.  We were unaware of that threat.  Various native milkweed species are found in so many parts of the world that we would always encourage butterfly gardeners to plant native whenever possible.

Dear Daniel,
I’m very honored and proud to receive the Bug Humanitarian citation.
My tree could be a “tree of life” or “tree of renewal” – its significance is equally applicable to any religion or frame of belief (or lack thereof).
No one can be offended by the breathtaking beauty and complexity of all of nature.
Best wishes,
Lane

I agree.  Before I knew about the problem I just bought what was at the big-box hardware store.  Maybe the Mexican species, being so hardy, is easier to ship – that or some other cost-motivated factor is probably behind it’s availability.  Next year I’ll seek out native plants.
Speaking of those big stores, their purchasing power has effects on the environment of which most individuals are unaware.  For example, cypress mulch is produced by horrible destruction to Florida and Louisiana coastal areas.  Cypress mulch should not be produced – they’re slow growing and no such thing as an excess of them.  I’ll get off my soapbox now!

Why stop now Lane?  We sometimes feel we are perpetually on a soap box, preaching about unnecessary carnage and the like.

I sat for almost an hour waiting for this shot. This was taken on a dock in Haliburton County, Ontario, Canada. She is absolutely gorgeous. The context is that the space she is sitting in is alomost 4” wide. We have always called them Dock spiders but it would be great to know if they have another name.

Fishing Spider with her Nursery Web

Dear Scott,
We try not to think too much about the letters that go unanswered, though we know that there are probably numerous overlooked gems that our readers will find interesting.  Today, we had a bit of time and we are randomly looking at unanswered requests.  We are thrilled we stumbled upon your submission.  We apologize for never responding earlier, especially since you waited for an hour to catch this awesome photo of a female Dock Spider or Fishing Spider,
Dolomedes tenebrosus (see BugGuide), protecting her Nursery Web full of spiderlings.  Many species in the genus are found in close proximity to the water and they are able to walk across the surface and dive beneath the water to escape predators.  Some are even known to hunt aquatic creatures like minnows and tadpoles, hence the common name Fishing Spider.  Like the rest of the family, these are hunting spiders that do not build webs, except for the care of their brood.  For that reason, they are also called Nursery Web Spiders.

Thank you Daniel.  I am glad you liked it.  I also managed to get a huge series of a male and female mating.  Interested?
Merry Christmas and all of the very besy in 2012

Assassin Bug from India

Hi again Juergen,
Thank you for sending a larger photo.  We have posted your request.  The detail in the larger image may help us identify the species of predatory Assassin Bug.

Karl provides an identification:  December 29, 2011
Re: Assassin Bug from India – December 19, 2011
Hi Daniel and Juergen:
I believe your Assassin Bug belongs to the genus Sycanus (Reduvidae: Harpactorinae). There are at least 18 species listed for India and many look quite similar, so getting a species identification is going to be difficult. You can check out these images of S. collaris from Thailand and S. croceovittatus from Hong Kong and Russia (?).  Both species look quite similar to your Assassin Bug and both also occur in India. The concern I have is that most, but not all, Sycanus species display a fairly prominent scutellar spine (sticking out from the middle of the back) and I don’t really see one in the posted image. Apparently the spine is sometimes missing from individuals of ‘spined’ species (I can’t see one on the bug featured in the Hong Kong link, above, either). It could be one of several species that have a reduced spine or none at all. Perhaps it is there but not visible due to lighting or the angle of the shot, or it may have lost its spine. I hope this helps. Regards. Karl

Advice on Raising Meal Worms requested

I know you’re terrifically busy in all senses of the word ‘terrific’, but I was hoping you might ask your entomologist backup crew to get in touch.
I’m starting out with mealworms and have some rather odd things going on in the colonies.  Major size differences in larval stage just before pupation and in pupae is only the beginning…!
I’m suspecting a mix of species, but which species?  Need to know so I can give them each their optimum environments, and I’m totally lost. icon smile Advice on Raising Meal Worms requested
Have pics, can send, can take more…
And any help, as always, is wonderfully appreciated!

You ROCK, folks…!
This is a picture of a darkling beetle, matured from one of my mealworm colony pupae–and in the next pictures, you can see there is a huge size difference between two distinct groups. Supplier A’s mealworms are larger at pupation and make large pupae; Supplier B’s mealworms are pupating at a smaller size and result in smaller pupae.
I suspect a mix of species–let me know what photos will be most helpful in ID’ing the darn things?
Thanks so very much for all you do–I swear, I recommend you to about six teachers a year. *evil grin*

Darkline Beetle: Mealworm

Dear Pamela and/or Onafixedincome,
Since your two emails came minutes apart, and deal with a similar subject matter, we suspect they are related despite different signatures and different email addresses.  Please confirm our suspicions.  Additionally, since only onafixedincome sent photos, we are treating this as a single posting and we will respond to both together.  Mealworms are a common commercial name for the larvae of Darkling Beetles that are raised as food for a variety of pets including larger tropical fish, turtles, lizards and frogs.  The Aquatic Community website has a nice page on Raising Mealworms.  The common commercial species is the Yellow Mealworm,
Tenebrio molitor, though we suspect other species may also be raised commercially, which might be one explanation for the size discrepancy you have witnessed.  Individual species also have considerable variation in size from individual to individual, and this may be partially explained by genetic traits.  Perhaps one supplier has individuals that are passing on a gene that is producing smaller larvae and pupae, and this is producing smaller adults.  We hope someone with experience will provide a comment to this posting, though sometimes comments take years to be posted.  We would recommend that you place a comment to this posting so that you will be notified in the future if there are any comments or answers to your questions.

Whups!  My apologies, wasn’t trying to be sneaky…Just brainless as usual, which takes little effort. icon sad Advice on Raising Meal Worms requested
I wasn’t going to send you pics, because they are ‘domestic’ insects, then thought you might find them fun, if not useful, so posted them.  The difference in emails was a screwup, and I am sorry.
Any rate, I appreciate your input as always!–can’t imagine how you manage to keep up with all this stuff.
Given the current average of malformation (50%+) thus far on the large pupae, I’m leaning toward the theory that these were treated with with growth hormone to get size–and that the beetles from these may well turn out sterile. icon sad Advice on Raising Meal Worms requested
So, I guess I’ll just have to wait and see….Much obliged for the link, it’s always good to learn as much as you can when raising anything, even bugs! icon smile Advice on Raising Meal Worms requested

Shield Bug from China

Tye Dye Colored Beetles
Location: Southern Yunnan, China

Bugman what is this bug! I’ve never quite seen anything like it before, I’m hoping someone here has so they can help me identify it. I was walking through the rice paddies in southern Yunnan province, China when these beetles caught my eye. Bright pink and violet with tye dye looking spots. I know pretty much nothing about beetles so as far as my description of them goes, I hope the pictures are enough. They were found in the mountains, maybe a mountain tropical environment. Help me bugman!

Jewel Bugs

Hi Erin,
We tried unsuccessfully to identify your species of Shield Bug from the family Scutelleridae, a group sometimes called Jewel Bugs because of their bright often metallic coloration.  We searched using both common names and the family name, and we were unable to find a match for your distinctly colored species.  Perhaps it has not been documented with photographs on the internet because of its remote location.  The Brisbane Insectwebsite has some good information and photographs of relatives from Australia.

All of your photos show Jewel Bugs on similar leaves, perhaps the food plant.  If we were able to identify the plant, it might help in the identification of your Jewel Bugs.

Thanks so much for the info.  Being the bad beetle photographer that I am, or at least not thinking about what plant they were on at the time I took these photographs, I had moved the bugs to be on that specific plant.  It was better than where one beetle was, on the ground walking past some animal scat.  So I’m afraid the plant won’t help.  But thanks so much for letting me know it’s a jewel bug of the Shield bug family.  I really appreciate your help.
Thanks!

Crane Fly, not Hanging Fly, from Costa Rica

Is this Bittacidae or Diptera? Or something else?
Location: unknown (will provide if later discovered)  Ed. Note:  Montezuma, Costa Rica
December 17, 2011 11:56 pm

http://i.imgur.com/qvPj4.jpg

My first guess is Bittacidae, but I’m used to seeing them with much thicker legs and longer antennae. The beak also looks unusual for a hangingfly and I can’t tell if it’s wingless. If it’s winged, most winged species rest their wings in a roof-like fashion (with the exception of Hylobittacus apicalis).

Hi Joseph,
If you don’t know the location, does that mean you did not take the photo?  Are you able to provide permission for us to post the photo?  We would also need assistance and we do not want to have the photographer contact us in the future to remove the image.
Please advise.

The photo was taken in Montezuma, Costa Rica.  The photographer is looking for an ID and is familiar with and is okay with the photo being posted on whatsthatbug.com.  He has already posted the photo on another public forum:

Thanks for getting back to us so quickly Joseph.  We agree with you and with several of the folks on the other public forum that this appears to be a Hanging Fly in the family Bittacidae which is represented by individuals on BugGuide that have more substantial legs.  We would not rule out a Crane Fly.  We will try to contact Dr. Chen Young at Carnegie Museum of Natural History and the Crane Flies of Pennsylvania website to see if he can provide anything conclusive.

Hi Daniel,
It is always nice to hear from you because your image always put a challenge to me and I like it.
This one is in the genus Orimarga, a small slender crane fly.

Spider Wasp and Huntsman Spider Prey

Dear Dom,
We have several excellent images of Australian Spider Wasps with Huntsman Spider prey in our archives.  The female Spider Wasp stings and paralyzes the Spider and then drags it back to her burrow to act as food for her brood.  The adult wasps feed on nectar.  We can imagine that it is a difficult task for the female Spider Wasp to locate her prey, sting it and then begin the long haul back to her burrow, and it is quite unfortunate that your broom hitting incident interrupted her task.  We hope that now that you are better informed, you will allow these food chain dramas to play out without unnecessary interventions in the future.

Bark Gnawing Beetle: Temnoscheila species

Emerald ash borer?
Location: Annapolis, Maryland
December 19, 2011 8:54 am
Hi, I found this insect while chopping wood. At first I was concerned that it was an emerald ash borer as it is the right size (14mm long) and shape. It’s head, especially the eyes and mandibles look quite different though.
It was dead when I found it, seemed to be attached to the wood by its rear end.
Thanks!

Dear ash borer?,
You are correct that this is not an Emerald Ash Borer, Agrilus planipennis, which is nicely represented in this excellent online pdf prepared by Gary L. Parsons of the Michigan State University Department of Entomology.  On page 55 of that pdf, we located a Bark Gnawing Beetle,
Temnoscheila virescens that appears to match your beetle.  It is described as:  “Length: 8.6-17.8 mm, slightly larger than EAB.  Color bright green or blue-green varying to almost dark purplish-blue, often with brassy reflections.  Head large, prognathous, and more evident than in Buprestidae, and the connection of the pronotum to mesothorax is narrowed, waist-like.  T. virescens occurs in the eastern U.S. with T. chlorodia (Mannerhiem), a very similar species, occurring in the western North America. Both species are predators found under the bark of dead trees where they feed on a variety of woodboring beetles.”  That Bark Gnawing Beetle can also be found on BugGuidealong with several other members of the genus.

On the genus page, BugGuideindicates:  “can inflict a painful bite if handled carelessly.”  Thanks for providing our archives with this convincing Emerald Ash Borer imposter.
