Hi
We saw this large black flying insect all over the beaches in the Whitsunday Islands. They were about 1.5 inches long, maybe a centimetre wide. They burrow into holes in the sand. They didn’t seem very interested in people, mostly ignoring us.
What on earth is it??
Thanks

Thread-Waisted Wasp

Thread-Waisted Wasp

Hi Jenny,
We don’t believe we will be able to provide you with a species identification based on your photos, but we can give you a more general family and subfamily identification.  This is most likely a Thread-Waisted Wasp in the family Sphecidae, and we are basing this on the anatomy of the wasp in your images, specifically the narrow “wasp waist” as well as the burrowing behavior.  Furthermore, we believe it is in the subfamily Sphecinae.  The Brisbane Insect website describes the subfamily:  “Wasps in subfamily Sphecinae are usually black in colour, from medium to large size. They have the abdomen link with thorax with very slender cylindrical stalk-like petiole, i.e. the thread-waist. They predatory on Orthoptera, including grasshoppers and katydids. Females build nest for their young by digging long tunnel in sandy ground. “

Your photos are most interesting to us on a behavioral level of the subfamily rather than as images of a specific species.

Hi bug an, can you tell me what spider this is. A simple search of “yellow striped spider” yielded nothing.
Thanks

Messy Leaf Curling Spider

Messy Leaf Curling Spider

Hi Ben,
We figured this might be an Orbweaver in the family Araneidae, so we browsed through the family on the Brisbane Insect and Spider site and quickly located the Messy Leaf Curling Spider,
Deliochus zelivira, which though the stripes on the individual pictured are white, otherwise resembles your spider.  The description fits as well stating:  “This spider builds large messy retreat by curling a few green and dry leaves bound together by silks. Male and female can be found in the same retreat during breeding season. Males of this species are more often seen because they wandering around looking for females. Matured females are in the messy large retreat and hardly be seen.”  Armed with a scientific name, we then located the Spiders of Australia website that pictures a yellow striped individual, but the family is indicated as Tetragnathidae, the Long-Jawed Orbweavers.  Arachne.org.au utilizes the same image and explains the taxonomy confusion by indicating:  “Deliochus zelivira, probably the most common of the Deliochus spp., found throughout Australia, appears to have been moved to Tetragnathidae then back to Araneidae. The female can grow to 11 mm, the male 5 mm. They construct a retreat of eucalypt leaves. ”  Dave’s Garden also has a photo.  All indications are that your individual is a male.

Camouflaged Neuropteran Larva:  Owlfly, Antlion or other???

Camouflaged Neuropteran Larva: Owlfly, Antlion or other???

Dear Emma,
What we know for certain is that this is the camouflaged larva of a Neuropteran, a member of the order that included Lacewings, Antlions and Owlflies.  In North America, there are many Lacewing Larvae that utilize this style of camouflage, but the mandibles on your individual look much larger.  We found this previously posted, but still unidentified camouflaged Neuropteran Larva in our archives.  The Owlfly Larvae pictured on the Brisbane Insect website have similar mandibles, but no camouflage.  The Antlion Larva pictured on the Brisbane Insect website also has similar mandibles, but again, no camouflage.
  The best we can provide at this time is that this is the camouflaged Larva of an insect in the order Neuroptera.  Hopefully, we will eventually determine a family, genus or even species identity.

Hi, we recently had a cyclone in the Pilbara region of Western Australia and on cleaning up the debris, I found this little guy. I have found a couple of photos on the net, but the name of the beetle continues to elude me. I hope you might be able to help identify this beetle. Thanks in advance.

Unknown Scarab Beetle

Flower Beetle:  Eupoecila inscripta

Hi Anthony,
We thought a beautiful and distinctive beetle such as this would be much easier to identify, but alas, a species or genus is eluding us.  We believe it may be a member of the Scarab Beetle subfamily Cetoniinae, known as the Flower Beetles in Australia.  This group includes the equally dramatic and beautiful Fiddler Beetle.  Perhaps we will have more luck later or perhaps one of our readers will come to our rescue with this identification.

Update:  Eupoecila inscripta
Thanks to a comment from Jacob, we were directed to Bowerbird where there is a nice set of images of the Flower Beetle, Eupoecila inscripta, and it looks like a perfect match to this lovely Scarab.  We also found a photo on FlickR.  The Atlas of Living Australia has sightings along the northern portion of West Australia.  We have already noted the similarity to the Fiddler Beetle, and our observation has some merit since the Fiddler Beetle, Eupoecila australasiae, is in the same genus that this Flower Beetle.

Hi guys,
All the best for the festive season and a fantastic new year. Hope you like this shot of the Blue Tiger Butterfly, seems a bit under represented on the site. They pass through my property on their migratory journey each year but it is rare to get one sitting still long enough for a shot.
Keep up the good work, till next year then,
best wishes

Blue Tiger Butterfly

Blue Tiger Butterfly

Hi Trevor,
Thanks for sending in your beautiful image.  We have to admit that for the past few days, we have been mostly fielding requests to identify Household Intruders and many of those images have been blurry and lacking in critical detail.  While cellular telephones allow folks to document things they encounter, the bottom line is that the quality of the images produced on the best portable communication devices pales when compared to the fine digital images that are produced with professional cameras when they are in trained artistic hands.  As the relevance of teaching photography comes under scrutiny due to budget cuts at the college level in America, we can’t help but to ponder the ubiquity of the photographic image and the importance good photographs play on successful websites.  Excellent quality images like your Blue Tiger Butterfly,
Tirumala hamata, help to make our humble website a more exciting place to visit.

I have taken photos and measured two of them a small one and a large one, the sizes are the smallest one 3mm and the larger one is 6mm.
Please help with identifing this bug. I dont want this bug to hurt my family especially my 5 month old daughter.

Unknown Heteropteran Nymph

Dear Ivan,
All three images you submitted are True Bugs in the suborder Heteroptera, and they are definitely NOT Springtails.  Two of your photos appear to be the same species and they are immature.  Due to their small size, we are speculating that they are either Dirt Colored Seed Bugs in the family Rhyparochromidae, or Chinch Bugs in the family Blissidae.  It may be difficult to determine the exact species as they are immature specimens.

The third photograph appears to be a different species, and it most closely resembles the Stink Bugs and Shield Bugs in the superfamily Pentatomoidea, but due to its small size, we cannot be certain.  It is a winged adult.  Compare your but to this North American Shield Bug Sphyrocoris obliquus that is pictured on BugGuide.  We are posting your photos and tagging them as unidentified.  We will attempt further research if time permits and perhaps one of our readers will be able to contribute some helpful information.  In our opinion, both species may present a nuisance due to their large numbers, but we don’t believe either species poses a direct threat to your family.
