female Argiope protensa
Fri, Jan 2, 2009 at 2:43 PM
Found this lovely lady in my vegetable patch. Thanks to Ron Atkinson (University of Southern Queensland) and Peter Chew (Brisbane Insects website) for ID of this member of the St Andrews Cross family. The orange stripes are generally not as pronounced as on this specimen but colour variation is apparently common amongst this species.

As always Trevor,
Thanks for your wonderful submission and identification.  The abdomen on this Argiope protensa is significantly different from that of most Argiope species.

Locust infected with mites?
Thu, Jan 1, 2009 at 8:48 PM
Hi guys,
This locust was very well disguised by colour and textures to fit in with the semi arid landscape and I only spotted it when it jumped out of my way. After processing the shot I noticed the little red attachments. Would they be some type of mite or some other parasite?

Locust with Mites

Locust with Mites

Hi Trevor,
Your Locust is in the suborder Caelifera and probably one of the Short Horned Grasshoppers in the family Acrididae.  We are not certain if the Mites are parasitic, but that is quite likely.  There are some mites that infest insects, but they are not parasitic.  Rather, they use the insect for transportation purposes, a phenomenon known as phoresy.  We are currently experiencing problems with images going live and hope to resolve this very soon.

Male Pollen Beetle (aussietrev)
Mon, Dec 29, 2008 at 8:04 PM
Hi guys,
This is a male Pollen beetle Dicranolaius bellulus in the family Melyridae (sex indicated by the enlarged 3rd segment of the antennae) Only around 8mm overall and very fast. The dark areas on the back are metallic blue/green depending on the lighting. I reckon that thorax looks like a Xmas cherry!
Happy New Year all

Pollen Beetle

Pollen Beetle

Hi Trevor,
Thanks for your wonderful image of a male Pollen Beetle.  We posted three new Australian beetles to the web site today.  The Csiro Entomology web site has a drawing of this species showing the enlarged antenna segment.  We can only speculate that those enlarged antennae segments have something to do with mate location.  The Brisbane Insect web site also has some photographs of this member of the family Melyridae, the Pollen Beetles.  This is our last posting for awhile.  We are wasting away the precious winter daylight hours in Los Angeles when we could be gardening.  We have some collard greens to harvest and much weeding to do.  Recent rains have saturated the soil and it is now the warmest day in over a week.

Large Flying Bug with big Pincers
Mon, Dec 29, 2008 at 5:31 PM
Hi Bugman,
We have just moved into our new house here in the Barossa Valley in South Australia. It is the middle of Summer and we seem to have a rather large bug invade us! It has 6 long legs and 2 very long antennae. IT is Brown in colour and seems capable of flying but doesn’t very much. It has 2 earwig type pincers that give a nasty bite. My 3 year old was pinched by one as it was hiding in his clothing. It seems like a giant earwig, and we have had a rather bad earwig problem here, but do they grow this big? It’s about 4cm long but I’ve seen ones that are up to about 6cm. It really clings on to thing, and are hard to shake off. THey seem to like dark places like clothing on the floor and we would like to get rid of them please! I cannot send a photo yet but will if it helps. Thanks.

Poinciana Longicorn

Parandra frenchi

Hi Kate,
We quickly identified your Poinciana Longicorn, Agrianome spinicollis, on the Csiro Entomology web site.  We then found additional images on the Insects of Townsville Australia web site.  The Save Our Waterways Now web site states:  “A common large species in Brisbane is Agrianome Spinicollis, a large khaki species, which often breeds in rot holes of poinciana trees.”  Pages 3 through 5 of a PDF (
hawskeswood160-1 ) we found has some technical information on this Prionid that is wide spread but uncommon in Australia.

Update:  January 30, 2012
With a new photo that arrived of the true Poinciana Longicorn, we are trying to clean up some errors in our archive.  This is actually
Parandra frenchi.  Trevor made a correction in a comment in February 2010, but alas, we did not update the posting until now.  We are also going to correct another posting from NOvember 21, 2009 where we used this same photo to illustrate a letter without an image.

Spotted Beetle (?)
Sun, Dec 28, 2008 at 8:22 PM
We found two of these fellows crawling on the inside of a lampshade. I’ve only seen one once before, in a bathroom in Northland, New Zealand. Both sightings were in houses with plenty of moderately untended garden, so they may have wandered in from there… any help identifying would be much appreciated.

Unknown Soldier Beetle

Unknown Soldier Beetle

Hi David,
We believe this is a Soldier Beetle in the family Cantharidae, but we cannot find a matching specimen on the Brisbane Insect web site. Perhaps one of our readers can provide a species specific identification for this distinctive beetle.

Correction
Nice image of what I’m thinking might be some kind of “false blister beetle” in the family Oedemeridae. I’m sending a query to my entomology listserv to see if anyone can confirm my suspicion of Oedemeridae, and perhaps give a genus and species….
Eric Eaton

Confirmation
Eric is right, it is an Oedemeridae. It the Spotted lax beetle, Parisopalpus nigronotatus, found in Australia and NZ.
Diane.

Thanks Diane and Eric,
Though we wanted to try to link to other online postings of this species, we only found one listing on the New Zealand Landcare Research web site without images.

Sydney, Australia – Longicorn?
Sat, Dec 27, 2008 at 8:53 PM
I thought that perhaps this is a type of longicorn beetle but I haven’t been able to find a description of a longicorn with similar antennae. This was found in December (our summer) in the Sydney suburb of Lane Cove. The body length is around 20mm. I’m interested to hear what you think I’ve found.

Longicorn Beetle

Longicorn Beetle

Hi Paul,
We agree that this is some species of Longicorn in the family Cerambycidae, possibly in the subfamily Prioninae. We would think a specimen this spectacular and distinctive would be easy to identify, but an identification is proving to be elusive for us. We found a new Australian website known as Insectographs, but could not find your beetle on it. We searched through all the Cerambycids on the Csiro Entomology page and the only one that looks close is the Feather-Horned Yellow Box Borer, Distichocera macleayi, but it is a mounted specimen. This may be a related species in the same genus, and we would not rule out the possibility that this is an introduced exotic specimen. We don’t feel confident with the Feather-Horned Yellow Box Borer identification unless someone else can write in to substantiate.

Daniel:
I lucked out just doing some calculated surfing:-) The beetle is Piesarthrius marginellus, indeed a longhorned beetle native to Australia. Neat insect!
Eric Eaton

Thanks Eric,
With the information you provided, we found the Feather-Horned Longicorn on a different Csiro Website than the one we originally searched as well as on the Up Close and Spineless website.

I meant to include the link I found:

Sorry ’bout that!
