Bark Mimicking Grasshopper

Long, thin, large, dark mottled fly
March 12, 2010
Dear What’s That Bug,
I’m a big fan and I believe I’ve written to you before. Tonight I found a sadly deceased large dark mottled fly of some sort. I’ve never seen anything like it before, not anything as big as that. It’s just turned Autumn here in South Australia and it hasn’t been raining or especially cold or unpleasant. I have in the last week or so cut back a lot of low branches on my pine trees and disturbed the underlying leaf litter but I didn’t see anything like this under there – mostly slaters, stink beetles and roaches. I suspect this poor critter is a victim of my cats – perhaps indirectly as I don’t think he would have easily fitted back out through the mesh of my enclosed veranda. I would have saved him/her if I could have, he/she is a real beauty.

Hi Bronwen,
We believe this is some species of Grasshopper, though the body has been traumatized and appears to be missing some legs.  We hope someone can assist in this identification.

Piotr Naskrecki identifies Bark Mimicking Grasshopper
Hi Daniel,
This is a bark-mimicking grasshopper (Coryphistes sp.), fam. Catantopidae.
Piotr

I did think it had a face like a grasshopper – but no thick strong jumping legs, and that fooled me; I just checked since I still have it in a jar and yes the back stumps are a bit more robust looking than the remaining legs. A large grasshopper doesn’t surprise me as much as if it was a large fancy winged fly, but still I’ve not seen one anything like that. We have water restrictions here and there isn’t much grass to be had so I’ve seen a lot more yellow and brown grasshoppers.
Thanks for your quick reply!
Cheers, Bronwen,

Desert Wolf Spider from Australia

Black and yellow spider
March 7, 2010
Myself and Haylee went spider hunting during an overnight stay in the bush near Cocklebiddy in WA, Australia . We found a few of these spiders and Haylee managed to get some good pictures of one of the few that didn’t dissapear down its burrow when we approached. We can’t seem to identify it despite searching online. Any ideas? Many Thanks.

Hi Charlie and Haylee,
This is possibly the most gorgeous Wolf Spider in the family Lycosidae we have ever seen.  The arrangement of the eyes is an identifying factor, and the explanation “These spider have eight dark eyes of unequal size arranged in three rows, the first having four eyes
” and a diagram are available on BugGuide.

We have not had any luck with a species identification, which surprises us as this is such a unique spider.  Perhaps one of our readers will have better luck and assist us with the identification.

Karl finds the answer again
It is a beauty!  The closest I could find was Hoggicosa (=Lycosa) bicolor, the Two-coloured or Desert Wolf Spider. There are several photos on the internet which look very similar, except that the colour is not such a vivid yellow. This may be a case of odd light conditions, regional colour variability or sexual dimorphism. It could also be a case of changing appearance with successive moults. In H. bicolor, the males apparently go from a striking two-tone appearance to totally cryptic in their final moult. I couldn’t determine if males and females look different. Here are a few links:

Cicada from Australia: maybe Golden Drummer???

Found him on campsite near the beach in Summer
March 5, 2010
Hello, i have just came back from a year down under and have some amazing pics of some of the strangest bugs and animals and insects i have ever seen. But there’s one in particular that we have to find out what it is. He found us on our campsite in Broome, Western Australia last Christmas, that’s there summer.
He was attacked by a bird and was shocked and we saved him. He stayed very still for maybe 20mins and then very loudly flew away happy to be breathing I’d imagine.
We traveled all of Australia and only ever came across this guy once. Maybe he’s native to the West Coast. Other than that i can’t say much more about him, I hope you guys can end our confusion, thanks.

Possibly Golden Drummer Cicada

Hi Ozbug,
This is a Cicada, and there are over 200 different species in Australia.  We could not locate an exact match for yours, and the angle of view is not ideal to see the markings, but your Cicada looks similar to the Golden Drummer Cicada, Thopha colorata.  We found a nice photo on Flickr.  Perhaps one of our readers will be able to verify or correct our identification.

Common Crow Chrysalis

Hi Justin,
We were struck by the similarity in appearance between your chrysalis and that of a Monarch Butterfly, so we did a quick web search for the Chrysalis of a Common Crow, a related species found in Australia.  The image that popped up from the Australian Museum website is nearly identical to your image. The Oz Animals website has nice images of the adult and caterpillar as well as this distinctive chrysalis of the Common Crow, Euploea core.

Hi again, I thought of checking out how many posts you’ve got on St. Andrew’s Cross Spiders, and was surprised to see only one (from Singapore). They are very common at our place, so I thought of taking some fresh photos of them for your site, but came across another spider that I haven’t seen before here, and took photos of it. So, I’m sending you a couple of older images that I’ve taken of the St. Andrews. Hope you can use them.

Hi Ridou,
Thanks for the excellent images.  We believe we had additional images of St. Andrew’s Cross Spiders, Argiope keyserlingi, and they might have gotten lost when we did a website migration last year.  We may check our old computer for the posts.  The Brisbane Insect website has nice images and helpful information on this species.

Golden Silk Spider in Australia: Nephila ornata possibly

A sizable new spider at our backyard.

Goodness gracious Ridou, you are keeping us busy,
This beauty is a female Golden Silk Spider in the genus Nephila.  There are numerous species in Australia, and we are not certain exactly what species this is.  The Spiders of Australia website has several identified and unidentified members of the genus.  We believe this might be Nephila ornata based on images posted on the Nature Stuff website.

Crab Spider from Australia: Sidymella rubrosignata

I quite like this small ‘two-headed green frog spider’ I found inside our house. Would you be able to identify it?
Best,

Crab Spider

Hi again Ridou,
This is a Crab Spider in the family Thomisidae, and there are several species pictured on the Brisbane Insect Website.  We are uncertain as to what species you have submitted, and part of our confusion arises from the variability of many species.  One North American species known as the Goldenrod Crab Spider, Misumena vatia, is known to be able to change its coloration based on the color of the flower or plant upon which it prowls for prey.  You can see some of these variations on BugGuide.  Crab Spiders are easily identified because the two pairs of front legs are considerably longer than the two pairs of hind legs.  We found many nice images of Crab Spiders on the Save Our Waterways website, and there is where we believe we matched your spider to Sidymella rubrosignata.  An image on Wikipedia supports that identification.

Lynx Spider eats Pod Boring Bug while Freeloader Flies share the feast in Australia

February 19, 2010
Hi guys,
Thanks for clearing up that velvet ant gender. This Lynx spider has caught herself a pod boring bug but is having to share it with minute flies that feed on the victims of spiders. I guess they must be immune to the effects of venom or feed before it has made its way through the body of the bug.

Common Lynx Spider and Freeloader Flies eat Pod Sucking Bug

Hi Trevor,
This is such an intricate Food Chain image and we are impressed with the excellent focus and detail on the individuals.  The Common Lynx Spider is well represented on the Brisbane Insect website, but the prey you have indicated, the Pod Sucking Bug, is not recognizable in your photo.  We did locate images of the Pod Sucking Bug, Riptortus serripes, on the Brisbane Insect website.  You sent us another example of Kleptoparasitism with Freeloader Flies last year, and we did extensive research at that time on the phenomenon.  These Freeloader Flies are in the family Milichiidae, and the Biology of Milichiidae page has this information:  “Another very interesting feature of Milichiidae behavior is kleptoparasitism or commensalism. Species of several genera suck at the prey of spiders or predatory insects such as Reduviidae, Asilidae, Mantidae, or Odonata. Mostly they are attracted to predators feeding on stink bugs (Pentatomidae) or squash bugs (Coreidae) (Frost 1913, Robinson & Robinson 1977, Sivinski & Stowe 1980, Landau & Gaylor 1987). In almost all cases it is only the females that are kleptoparasitic. In some cases a close association between milichiid and predator has been postulated, because it was observed that the fly “rides” on the predator for some time, staying with the one predator rather than changing between different predators (Biró 1899, Robinson & Robinson 1977).
“  Irina Brake is the expert on this fascinating family.
Interestingly, in the past two days, we have received numerous beetle corrections from a Dr. Trevor J Hawkeswood of Australia, and we lamented that we have not had any recent submissions from you.
