Tachinid Fly, we think

Tachinid Fly, we think

Hi Nick,
We would not have expected such a distinctive looking fly to be so elusive to properly identify.  We believe it is a Tachinid Fly, though we could not identify it on the Brisbane Insect Website, nor the Life Unseen website.  There is a body of an Euamphibolia Fly on the Life Unseen website that looks quite close, but we could not locate another image to substantiate that.  Perhaps one of our readers can assist with this identification.  We also had a vague recollection of seeing a similar photo in the past, and sure enough, we found a still unidentified posting in our archive.

Yes, I do think the black and white fly is a tachinid, but have no idea how to explain it, or be able to be conclusive, either…..I’ll keep looking for an answer.

Hi Daniel,
many thanks, I have sent the image off to the CSIRO head of entymology for id (if possible) it seems going from the other posting earlier that it is in the same area Cygnet is approx 15 mile from my area.
just in time for christmas, if i receive a response from CSIRO i will let you know, thanks again for responding so quickly..
regards
Nick.

Update

Hi Daniel,
I have a name !
response from CSIRO
Hi Nick,
This is a bristle fly, Amphibolia vidua (Tachinidae), one of perhaps 3-4,000 species of this family occurring in Australia.  Its larvae feed as a parasite internally on other insects.  On sunny days in summer the adults often rest on smooth eucalypt tree trunks, and similar structures such as poles and pipes.
Best
Thanks again Daniel.
kindest Regards

Some sort of assassin bug?
December 10, 2009
The other day my girlfriend ran into the room holding a bug that had been biting her arm. It was a tiny Hemiptera that, legs and all, would be only the size of someones fingernail. We examined it for a while then released it back out into the garden only to find dozens more. Despite the aggressive first encounter they proved to be very pretty, shy little things and proved to be rather difficult to photograph.
These pictures were taken in Taree NSW, Australia in early-mid summer.
My suspicion is that they are an assassin bug, or something similar. I hope you will be able to narrow it down for me.

Dear Jish,
Nymphs are sometimes difficult to properly identify, but we believe this is an immature Common Assassin Bug, Pristhesancus plagipennis, which we identified on the Brisbane Insect website.

Are these bed bugs?
December 12, 2009
Hi,
I’m living in Sydney Australia in an apartment and in the last month (summer just started) my place has become infested with these bugs. They seem to have pointy and long mouth parts. They climb the walls, fall, and then get stuck in the carpets… I have attached 2 pics using a microscope (4X magnification). One is a dead bug and the other is immersed in oil to get it to stay still. They are both 0.2 cm long. Your help would be greatly appreciated. Thanks.

Hi EAW,
This is a Weevil, and we suspect it may be infesting some food product in the pantry, possibly rice.

Thank you!
Thank you so much for your quick reply. I have found the culprit. A 5 kilo bag of wild bird seed in the closet.
Thanks again.

Hi Lee-Anne,
This is a Golden Green Stag Beetle, Lamprima latreillii, based on images posted to the Brisbane Insect website.  Another possibility is the closely related Lamprima aurata which is pictured on the InsectaCulture website.

Hi guys,
Hope the book is progressing well. Will you have it for sale on the site? Thought you might like this shot of Suppuna Picta finishing off a male Dinopis ravidus (Net casting spider)

Hi Trevor,
Nice of you to ask about the book.  Coincidentally, we sent off the first draft today.  Now we wait for the editor’s comments before beginning to rewrite.  We had to correct the spelling on Supunna picta before we could find a link.  Thanks for the great photo.  Interesting that the Bug Mimicking Swift Spider mimics the nymphs of the Gum Tree Shield Bug.

Need more information
November 21, 2009
Hey bugman,
I’m from Woodford, Queensland in Australia, and have recently had an increasing (then decreasing) number of what I have found out (from your site) to be Brown Prionids. A good deal of my room is made of timber from the timber yard next door, and I have a full length porch made from said timber around my room. Just wondering if these beetles are dangerous in any way. The pincers on these buggers are freaking my missus out BIG TIME! And the little buggers have flown across the room, brushed my face while lying down, and freaked my missus out a few times. Any further information than that I have already read about them on this site would be greatly appreciated.
Thank you in advance,
Nathan from Brisbane
We don’t see bugs like this in Australia, really…. :-S

Poinciana Longicorn from our archives

Ed. Note:  January 30, 2012
The included photo came from another posting and is replacing a photo we originally incorrectly identified as the Poinciana Longicorn.

Hi Nathan,
Though our website has gotten you a subfamily identification, we actually believe your species may be local for you.  In our opinion, this may be a Poinciana Longicorn, Agrianome spinicollis, or perhaps some closely related species.  When you say your room is made from the timber from the timber yard next door, you did not indicate when the room was constructed.  Often fresh timber is milled with beetle larvae inside, and if the wood is not treated, the adults may eventually emerge.  Also, if you live in an area where milled wood is produced, you may just be attracting the beetles because many Prionids are attracted to lights.  The mandibles on Prionids are quite strong since they need to chew their way out of the trees they have been boring in during the larval stage.  A bite might even draw blood, but it will heal as there is no poison.  Perhaps someone will write in an confirm that our identification is correct.  We posted a photo of a Poinciana Longicorn several years ago, and there is also a link to a site with some photos.  Your specimen seems a richer color than the images we found online.  Sadly, the Brisbane Insect website has nothing devoted to the subfamily Prioninae.

Hey Daniel,
The house was built roughly 5 years ago. These beetles have only JUST started to show up. The owners of the house before us have stated they have no idea what we’re on about because they didn’t have them. As I said, they seemed to show up almost every night (for about 2 weeks), then all of a sudden they stopped showing up as often. We now see 1 every now and then. Ironically, the beetles stopped showing up as often when we caught one and kept it in a bottle. They must be tough bugs, because this bugger lasted 2 weeks without food, water or air…
And the picture I included was one I found on the internet. I didn’t have a camera on me when I sent that message to you. In actuality, the beetles we have here are a deep brown colour, as opposed to the rich red-like colour in the photo.
Nathan

Hi Again Nathan,
We wish you had indicated that the beetle in your photo was just some random similar looking specimen, because as you should realize, any accurate identification is now impossible.  We will be removing the image from your letter (since we do not have the photographer’s permission to use it) and replacing it with the likeliest suspect, the Poinciana Longicorn.  Often there are years with population explosions of some species, generally triggered when conditions are perfect.  While it is possible that the beetles have been in the larval stage in the wood of your house for the past five years, we do not consider that as strong a possibility as them entering the home from the outside after being attracted to the lights.

Hey Daniel,
First off, my apologies for including a random shot of the beetle from the internet. But as your inquiry form would not allow me to continue without a photo (and the fact I didn’t have a camera on me at the time) I grabbed the next best thing.
I ran an image search of this Poinciana Longihorn, and found a closer image match to this beetle than I originally did, so I now have a better idea of what this bug is, thank you. And I’m not sure if they are actually attracted to the lights, per say, because if you leave the doors open, they DO enter (and the outside lights are always on of a night). Every time I have accidentally left the door open, I see them flying in. So needless to say, I now make every conceivable effort to keep the house closed up of a night.
A larval stage of 5 years??? Freaky… 🙂
Anyways, I want to thank you for helping me trying to understand this small creature and giving me a little more appreciation for them. I no longer kill them. Rather, pick them up with some paper and a glass, and set them back into the backyard.
Cheers,
Nathan
