Readers’ wildlife photos

August 11, 2018 • 7:45 am

Reader Tony Eales from Australia sends some camouflaged beasties and a brightly colored spider. His notes are indented.

Some camouflage.

A Brisbane Two-tailed Spider, Tamopsis brisbanensis, on a mangrove tree trunk. These are very hard to spot. They have a leg span of around 3 or 4 cm. I believe the one in the photograph has some securely wrapped prey in front of it on the bark but even this is well camouflaged. I found this video of a slightly different species of Two-tailed spider catching prey:  https://youtu.be/6uo1rPHxlRI

I’ve sent a Flat-headed Leafhopper (Ledromorpha planirostris) nymph as a spot the before, but I saw another one just recently. I’ve attached a long shot, a close up and the reveal.

At the opposite end of the spectrum from camouflage, I found another species of Peacock Jumping Spider. This one is Maratus nigromaculatus.

I’ve also included a picture of one of our really common and colourful bugs. It is a male Cotton Harlequin Bug (Tectocoris diophthalmus). Females are orange with iridescent green blotches, and the nymphs are iridescent dark blue with red patches. They love hibiscus, especially the tree-sized ones we have around here called Cotton Trees (Hibiscus tiliaceus).

And lastly a katydid genus Polichne. There’s a lot of undescribed and hard to distinguish species in this genera.

 

Readers’ wildlife photos; special “spot the. . . ” edition

October 6, 2017 • 7:45 am

Reader Tony Eales from Oz sent some camouflaged arthropods. These aren’t all that hard to see, as they were specially photographed to show the beast, but the photos do underscore the wonders of natural selection. His notes are indented:

Camouflage. A series of the cryptic to the near invisible.

First is a geometrid moth caterpillar. I was very lucky to see it on the bark of this native caper tree (Capparis mitchellii):

Next is the nymph of the world’s largest leaf-hopper Ledromorpha planirostris. These are very common on the bark of blue-gum trees but because of how they are flat and cryptically coloured they are often missed. Almost worthy of a spot-the! [JAC: this is a hard one!]

Next is a type of Crab Spider (Thomisidae) Stephanopis sp. These spiders have such good patterning and hairs and knobs to break up their outline they sometimes make your eyes swim looking at them on bark and trying to make out where the spider ends and the bark begins.

I was lucky to see this caterpillar for the White Banded Plane (Phaedyma sheperdi) out on a green leaf or I would have over-looked it. As it was I thought it was a weird chrysalis but it was just the way the caterpillar holds itself.

This one is amazing:

Last is one of my favourites, the Wrap Around Spider (Dolophones conifera). The way they perfectly wrap around small twigs and just look like a small bump is extraordinary. The only way I’ve ever found them is as they flee from their orb-web as I approach because once they’re on a twig they’re pretty much invisible.

Here’s a photo from The Daily Mail:

A very cryptic frog

December 30, 2016 • 12:45 pm

From a tw**t by J. Rowley (h/t: Matthew Cobb), we have a very cryptic frog; the caption is “From #Moss to #Frog in a single move. It’s no wonder this species is called the Vietnam Moss Frog (Theloderma corticale)!” Actually, it’s called the “mossy frog”, is semiaquatic, and lives in the primary evergreen forests of Southeast Asia.

To enhance the crypsis, they curl up in a ball, like the one on the left, to hide their froggyness:c04gcijuqaao0ii

Spot the lappet moth larva!

September 25, 2016 • 5:00 pm

Well, the answer is here, so I just wanted you to see this. The caterpillar is, of course, a larva, and the lappet moth is Phyllodesma americana.

The adult, when resting on bark, is also cryptic. Note how the head is tucked down and hidden:lappetmothphyllodesmaamericana

Here’s another picture of the caterpillar; don’t ask me whether they can change colors (either within one period or depending on their habitat) or come in different colors”

Spot the moth(S)!

August 28, 2016 • 8:45 am

We have another visual stumper today, and this is a hard one. It comes from reader Mark Sturtevant. First his notes and the picture, and I’ll give the reveal later:

A funny thing happened when I was preparing this picture. I found a large underwing moth [Catocala sp.] on a dead tree trunk, and immediately set about taking pictures. One picture was taken at a distance so that the readers of WEIT might enjoy trying to find it. That moth is actually not too hard to find, but when I was preparing the picture to be sent to you I found a second underwing moth in the picture!  I was at this tree for nearly an hour (there was a huge syrphid fly that also needed its picture taken), and I had no idea that the second moth was there. I am still pretty giggly about it.

Anyway, the readers will know what to do. But that 2nd one…. Let’s say your readers might go through a pot of tea before they find it. Good luck!

I’ll put up the reveal at about 1 pm Chicago time, just to give you plenty of time to spot the two moths.

Although these moths have brightly marked hindwings, they’re always covered by the highly cryptic forewings when the moths are hiding (they probably evolved to startle predators). You can see some photos of underwing moths here.

Oh, and try not to give away the locations of the moths in the comments. But if you found both, feel free to proclaim your perspicacity!

Here are the insects!

Here’s today’s “where’s the __” reveal. Above the fold I’ll show the original photos, and then click “Read more” at the very bottom to see the reveals.

From reader Barn Owl: there’s a stick insect here:

And a hidden grass moth from reader Gabe McNett:

Spot the scorpionfish

May 2, 2016 • 7:00 am

Reader Gayle Ferguson, you may recall, is a biologist at Massey University in Aukland, New Zealand (she once worked with Matthew in Manchester), and rescues batch after batch of orphaned kittens, for which she gets the title of Official Website Kitten Rescuer™. (One of the kittens she saved is Jerry Coyne the Cat.) She also does scuba diving, and took this photo of a camouflaged baby scorpionfish.

Gayle’s notes say “Photo taken on a scuba dive at the Poor Knights Islands off Tutukaka on the East Coast near Whangarei.”

Can you see it? It’s not terribly hard, but does show some nice camouflage:
