Long Nose Lycid Beetle
Location: Queensland Australia

Hi bugman, been a while since i sent you anything. I have went to Australia since my last submission.
What we have here is the Porrostoma rhipidium – Long nose Lycid Beetle. He is a very docile and somewhat curious critter. He crawled around on me while i took many shots.. then as I let him go, he landed beside of me and continued hanging around in the yard for another entire day.

Long-Nosed Lycid Beetle

Dear SCWIDVICIOUS,
Thanks so much for sending us this marvelous submission.  The Brisbane Insect Websitehas many excellent images of this species.  Members of the family Lycidae are commonly called Net-Winged Beetles and they are somewhat unusual in that they have soft elytra, unlike most beetles.  Now that winter is approaching in the northern hemisphere, we are expecting a surge in submissions from Australia if our typical annual cycle remains unchanged.

Orange/black mystery bug
Location: Radnor, Pennsylvania (suburban Philly)

I saw this insect sitting on my car this past week and don’t recall ever seeing it before. The body/wings are about 5/8” long and with the antennae it was just over 1 inch total length. I’ve so far not been able to get an ID on what it is.

Banded Net-Wing Beetle

Hi Orla,
This little beauty is a Banded Net-Wing Beetle,
Calopteron reticulatum.  It is a generally accepted theory that orange and black insects display aposomatic coloration to dissuade predators, either because they are dangerous, or poisonous, or don’t taste good.  The Banded Net-Wing Beetle is not dangerous or poisonous, and taste is relative.  It may be part of a complex mimicry system that includes some moths and some wasps.  The wasps sting, and insects that mimic them may benefit from the protection the wasps enjoy because of their stinging capacity.  This is speculative editorialization on the part of our staff, and not something we can cite.  You may turn to BugGuide for additional information on the Banded Net-Wing Beetle.

Wonders from Malaysian Borneo!

Hey Bug-people!
A challenge for you!
I took myself backpacking through Southeast Asia a while ago, and came back with some amazing pictures of bugs.
I’ve included three of what were to me the most fascinating and baffling varieties. Can you help me identify them?
Cheers!

Netwing Beetle Larva, or Firefly Larva

Hi again Doug,
We have split up your question into separate postings.  …  Your third insect is a larval Firefly not unlike this North American example.  Did we meet your challenge?

Wow!  I guess everything’s bigger on Borneo, because that larval Firefly was  nearly three inches long!
Thanks for that. The info about the flatworm was particularly fascinating.
Doug

Hi again Doug,
We are ready to research the Bornean Firefly Larva, though we cannot discount that it might be a Netwing Beetle Larvae.  Eric Eaton says the way to tell the difference it to introduce a snail.  If the beetle larva eats the snail, it is a Firefly Larva.  If it prefers fungus, it is a Netwing Beetle Larva.  We imagine that there may also be snail and fungus specificity in the preferences.  Here is an example from The Flying Kiwi of a Larviform female Netwing Beetle from Viet Nam, and here is another example of a Netwing Beetle and The Flying Kiwi‘s, AKA Richard Seaman’s, written account:  “I didn’t notice that this one in Malaysia was glowing, but it turns out that both this and the Vietnamese “firefly” aren’t fireflies at all, they’re actually the larvae of net-winged beetles in the genus Duliticola, otherwise known as “trilobite larvae” because of their prehistoric shape; the one you see here is Duliticola hoiseni.   The drops of liquid on this one’s back look like they are some toxic substance exuded for protection, I’m not sure if that was for my benefit or whether it was already feeling stressed when I arrived.” Interestingly, last year Bert traveled to Malaysia and he sent us a Netwing Beetle or Firefly Larva as well as a Land Planarian.  Though there are similarities, they are both distinctly different for your examples.  We imagine there is great diversity in the jungles, and there may also be distinct local populations that over time have developed into distinctly different looking relatives that may or may not be different species.

What is this bug?
Location: Wickenburg Arizona
May 24, 2011 8:19 pm
Found this a couple days ago crawling along the wall in the front yard. it’s about an inch+ long – we are located about 60 miles NW of Phoenix Arizona. Medium/High desert – summer will get highs of 105 and some nights below freezing in the winter. I asked my dad who has lived in this area for over 30yrs and he didn’t know what it was either. I just let it go on it’s way but got the photo first.

Newly Metamorphosed Net-Winged Beetle

Hi Tammy,
This is a Net-Winged Beetle.  Because of its engorged abdomen and the relatively small size of its wings, we believe it is a freshly metamorphosed individual.  The wings will increase in size and harden slightly so that the Net-Winged Beetle will be able to fly.  Net-Winged Beetles are frequently confused with moths.  We believe your individual is in the genus
Lycus based on photos and information posted to BugGuide.

Golden Net-Wing

Dear c,
This is a positively gorgeous photo is a beetle, the Golden Net-Wing,
Dictyoptera aurora.  According to BugGuide,  they are:  “Typically seen early spring. May (Minnesota). North Carolina: March-April (June in mountains), and sometimes September, December.”  BugGuide also question: “Larvae are predators under bark (2). Active in early spring, adults often found on rotting logs. Adults overwinter?”  Net Winges Beetles are closely related to Fireflies and Soldier Beetles.

Net-Winged Beetle

Hi Glen,
This sure looks like a Net-Winged Beetle in the family Lycidae to us.   We absolutely love your rapid series of photos depicting this individual about to take flight.
