Mole Cricket

Dear Mrbug3,
Mole Crickets are one of our most common identification requests, and not just from Australia, but from many parts of the world as far apart as North America and the Middle East.

Found this in a nature reserve behind our house in Seacliff (near Adelaide) Australia. Any idea what this is?

Vine Hawkmoth Caterpillar

Dear Stuart,
This is a Vine Hawkmoth Caterpillar,
Hippotion celerio.  We just posted a green individual this morning.  According to Butterfly House:  “This Caterpillar occurs world-wide. It can occur in several different colour forms: green, brown, red or dark grey. It usually has an eyespot each side of the first and second abdominal segments, those on the first segment being larger.”

Hi I found this caterpillar in my grapevine today. I’ve not seen anything like it. Could you tell me what sort is it and is it harmful to us?
Regards

Vine Hawkmoth Caterpillar

Dear Fiona,
Cultivated grape is one of a list of plants on Butterfly House that serve as larval food plants for the Vine Hawkmoth Caterpillar,
Hippotion celerio.  The Vine Hawkmoth Caterpillar is not dangerous to humans.

So a friend of mine found these larvae(?) in his fish pond, dozens of them, they breathe through a snorkel and are almost an inch long. I have yet to see them in person, but I don’t seem to be able to find anything that fits closely and hes never had them before. Maybe of note is that we have had a lot of rain lately so perhaps they are thriving because of all of the fresh rainwater and his pond only has floating duckweed and salvinia. Does he need to be worried about his smaller baby fish if these are carnivorous?

Mosquito Larvae

Dear Ashton,
What kind of fish does your friend have?  We would think fish would gobble up these Mosquito Larvae.  Your friend might want to consider adding some Mosquito Fish to the pond to help eliminate these aquatic larvae that will eventually become blood-sucking, flying Mosquitoes.   Here is a Getty Images image to support our identification.  Here is a larval comparison image from NSW Arbovirus Surveillance & Vector Monitoring Program.  Mosquito Larvae are commonly called Wrigglers.

Thank you for the photo references.
He has koi fish which logically should be eating them.
Its weird though ive never seen wrigglers as large as he was telling me as i personally collect them to feed to my aquarium fish at home. What he explained was that they were the size of grubs. Hes collected wrigglers for his smaller fish for years and has never had ones like these so maybe theyre from a different species of mosquitoe to usual.

Update:  April 10, 2017
On second look, they look a lot like the culex variety. Will have to research mosquitoe varieties in my local sydney area.

Vine Hawkmoth Caterpillar

Dear Corma,
This distinctive Hornworm is a Vine Hawkmoth Caterpillar,
Hippotion celerio, which we identified on the Butterfly House website where it states:  “This Caterpillar occurs world-wide. It can occur in several different colour forms: green, brown, red or dark grey. It usually has an eyespot each side of the first and second abdominal segments, those on the first segment being larger.”  The eyespots may act as protective mimicry if a predator mistakes a tasty caterpillar for a larger threat, and the Caterpillar’s behavior, as explained on Butterfly House, supports that:  “When disturbed, the caterpillar curls into the shape of a letter ‘C’, tucks its head under its thorax, and expands the segments with the eyespots. No doubt these distract and deter possible predators.”  Since this species has such a wide range, it is known by different common names in different locations.

Dear bug man.
We were at a local park and saw this reddish brown caterpillar type bug with a stinger on the tip of its tail. It only had 6 legs that we could see
We took a photo to try to help us identify it.
My 11year old mitchell is fascinated

Long-tailed Sawfly Larva

Dear Nicole,
Though it resembles a Caterpillar, this is actually the larva of a Sawfly.  Sawflies are non-stinging relatives of Wasps and Bees, and adult Sawflies are generally mistaken for Wasps or Flies.  Based on images posted to the Brisbane Insect website, we believe your individual is in the subfamily Pterygophorinae, the Long-Tailed Sawflies.
