Your letter to the bugman:  I snapped this beauty outside a fish and chip shop on the weekend, taking a rest on a kerb, which would make it about 15cm from front legs to wing tips. I have no idea what sort it is, though, and haven’t seen one before. Can you help? It would be good to put a name to the face, as it were.

Wattle Goat Moth, we believe

Dear Joshua,
This appears to be one of the Wood Moths or Goat Moths in the family Cossidae, possibly the Wattle Goat Moth,
Endoxyla encalypti, which is pictured on Butterfly House where it states:  “The adult moths have forewings that are speckled grey and brown with indistinct light and dark streaks. The hindwings are reddish-brown at the base, fading to grey-brown at the margins. The wingspan is around 10 cms.  The thorax of the adult moth has an uncanny likeness to the head of a mouse! The ‘eyes’ of the mouse are the thicker parts of the bluish lines running on either side of the thorax, located just behind the real eyes.”

Thanks Daniel. The wingspan of this individual was definitely greater than 10cm, but that does look a very close match. Appreciate the help!

Your letter to the bugman:  This is currently on my lime tree and not moving.  I thought it was a butterfly but the head looks like a lizard or snake.

Orange Dog

That’s ok!  I found it!  It’s a skull caterpillar! A Very cool bug indeed.
Rita
I love that you get so many photos of weird bugs that you cannot answer them all.

Dear Rita,
We are not certain where you found the name “Skull Caterpillar” but we do know that Orange Dog is a commonly used name for the caterpillar of the Giant Swallowtail.  The markings on the Orange Dog, which feeds on the leaves of orange trees and other members of the citrus family, are thought to mimic bird dropping for protection.

I found this insect, but it seems unidentifyable. Can you help me to identify it, please?

Longicorn: Dorcadion (Cribridorcadion) decipiens

Dear RS,
Your global coordinates indicate this sighting was made in Romania.  This is a Longicorn in the family Cerambycidae, and we quickly identified it as
Dorcadion (Cribridorcadion) decipiens thanks to Cerambycidae where it indicates the distribution is “Hungary, Romania, Serbia, Monte Negro, Moldova.” 

Dear Daniel,
Thanks a lot for the answer and for Dorcadion (Cribridorcadion) decipiensc identification, which were a big help for me.

Remains of a Centipede

Dear Fi,
Your image is of the partial remains of a Giant Centipede, possibly 
Ethmostigmus rubripes.  According to The Australian Museum:  “This is the largest native Australian centipede and is a member of the scolopendrid family.”  The site also states:  “The Giant Centipede ranges in colour from dark blue-green-brown to orange-yelllow.  It has black bands along the body and yellow legs and antenna.  The body is long and flatterned with 25 or 27 body segments and 21 or 23 pairs of legs. The first pair of legs behind the head are modified claws which curve around its head and can deliver venom into its prey. The venom is toxic to both mammals and insects, but does not appear to be strong enough to kill large animals quickly.”  We can only speculate on why you only discovered the posterior remains.  Perhaps a predator like a bird or lizard ate the front end of the Giant Centipede. 

Thanks.  Yes, that makes sense.

Subject:  I think it is under the order Mecoptera

Your letter to the bugman:  Hello,
I live in Sydney Australia and it is currently late spring.
I spotted this insect on my balcony and think it is under the order Mecoptera. I tried to catch it to give to donate to the entomology department at the University of Sydney because I know they don’t have many.
I am very interested in knowing what type of insect it is because I spent 3 months catching insect for my entomology major work and just handed it in. Shame I didn’t find one 3 week earlier!
Thank you for your time.

Giant Blue Robber Fly

Dear Ethan,
This is definitely NOT a Scorpionfly in the order Mecoptera.  It is a True Fly in the order Diptera, and we believe it is a Robber Fly in the family Asilidae.  We believe it might be a Giant Blue Robber Fly,
Blepharotes spendidissimus, which is pictured on Brisbane Insects where it states:  “The Giant Blue Robber Fly has the relatively small head, legs are not long but with board abdomen. The body and legs is covered with short grey hairs. Whole body, includes eyes, abdomen and legs are in dark steel blue colour. Pair of Wings are tinted in steel blue as well. “

Your letter to the bugman:  This was on our lanai. Body looks like a stick. The wings look like wood. The legs were white and completely blended into the wall paint color. Was about 1- 2 inches long. Very cool.
