Hi,
Thank you so much for all of your service throughout the years. I often make donations & spread the word!
This latest bug is stumping me: We live in east Los Angeles near Pasadena & the SGV (inland)- tonight I noticed approx 20-30 fruit-fly-esque bugs dead or dying in the bathroom sink. They seemed to be coming in through a tiny opening in the bathroom window, so my husband went to the roof to check it out. He said there are thousands on our roof!! He’s spraying now but we can’t find anything similar-looking enough online.
They seem to obviously be attracted to water but do not look like drain bugs.
PLEASE HELP!
(We’re so worried they’re termites but they don’t have long wings)

Argentine Ant Alate

Argentine Ant Alate

Dear Meg,
The person who can solve your infestation problem will probably win a Nobel Peace Prize as the solution will improve the quality of life for Californians, the people of Japan and the inhabitants of the Mediterranean, as those are the three places where super-colonies of Argentine Ants,
 Linepithema humile, are making millions of people’s lives miserable, especially in hot summer months when 1000s of Argentine Ants invade homes in search of food and water.  Your images are of winged reproductive queen and king Argentine Ants, known as alates, on their nuptial flight and according to BugGuide:  “Winged queens mate once with a winged male, after which they can continuously produce fertile eggs for as long as 10 years- until death. Unlike most ants, several productive queens of this species can share the same colony, with one or more leaving with some of the workers to form a new colony when it gets crowded (this is known as ‘budding’).”  Here are some good images on BugGuide for comparison.

Bulldog Ant Alate

Bulldog Ant Alate

Dear Julie,
This is a Bulldog Ant or Bull Ant in the genus
Myrmecia, and it is a winged reproductive individual known as an Alate.  According to the Australian Museum site:  “Bull ants are large, alert ants that can grow up to 40 mm  They have characteristic large eyes and long, slender mandibles and a potent venom-loaded sting. They have superior vision, able to track and even follow intruders from a distance of 1 metre. Many species of bull ants have bright red or orange colours on the head or abdomen.”  The site also states:  “These ants can deliver painful stings and are aggressive. An ice pack or commercially available spray may be used to relieve the pain of the sting. If there is evidence of an allergic reaction, medical attention should be sought.”  There is also an image on Oz Animals.

I live in Inverness, FL. I just started noticing these bugs in the last few days. They are everywhere. I just went to the gas station and they were covering the pumps and the awning over the pumps. Then I came home and they are all over the outside of my house and under the roof overhang. What are they? Do they bite or sting? There were hundreds of them at the gas station. There are so many that it reminds me of when the love bugs swarm twice a year. Thank you!

Ant Alate

Female Carpenter Ant Alate

Dear concerned mom,
These are winged, reproductive Ants, known as Alates.  It appears that you have submitted images of both a male and a female Carpenter Ant Alate.  The individual with the longer, thinner antennae is a male, which we matched to this image on BugGuide of a male Red Carpenter Ant,
 Camponotus castaneus.  When conditions are right, Ants from the same species will mate at approximately the same time, helping to ensure that there is some crossing between different colonies which diversifies the gene pool.  We cannot state with certainty the species, but we are rather confident we have the genus Camponotus correct.  Though a bite may occur if they are carelessly handled, these Carpenter Ants are not considered to be dangerous.

Subject: Curious red forest ants with prey
Location: Cherokee County, NC

Photo was taken on 1st April 2015
Here are some odd red ants that I’ve never been able to identify. They seem to be about a uniform ~6-7mm in body length. I’ve only found these in rather specific environments; mixed deciduous forest in Western NC/ North GA with plenty of moist rotted logs and tree stumps. Tree stumps in particular with abandoned insect and carpenter ant tunnels seem to be their favorite; they take up residence in the old tunnels and clean them out to their liking. Colonies I’ve seen seem small with maybe a few hundred individuals at most, though to my recollection I’ve never seen a queen amongst the ones I’ve stumbled upon.
They seem to be primarily carnivorous; when I do find them there’s usually several small groups hauling various forest floor insects like crickets and beetle larvae into their tunnels. The ones in the photo here had what might be a newly-molted cricket nymph.
One distinct aspect is that their movement is rather different from other ants I’ve encountered; they seem to more more slowly/methodically, like the way an assassin bug moves. Even when disturbed they’re more slow to scurry about.
Finally, I couldn’t take a photo that included it but there’s a slight but rather distinct berry-red adularescence/schiller effect to the back of their abdomens when they’re in the light. For some reason my camera failed to capture it.

Dear Jacob,
We are posting your ant image and labeling it unidentified.  We are also featuring the posting.  We hope to be able to provide you with an identification soon.

Subject: Boring insect larvae in SoCal Mimosa tree
Location: Escondido, California
March 22, 2015 4:13 pm
We planted a Mimosa tree (Albizia julibrissin, a.k.a. Silk Tree) 6 weeks ago, and it just started budding out during the recent warm weather. Unfortunately, we are also now seeing insect larvae coming out of some of the small branches. Now that we know what to look for, we see dried up wounds in other parts of the tree, presumably from a previous season’s larval activity. The attached photo, showing active larvae, is of a branch about 1/2 inch in diameter. Can you identify this insect, and do you know of any treatment?
We are in Escondido, CA, which is 20 miles north of San Diego and 10 miles inland.
Thanks!

Dear Joe,
These are not wood boring insects.  They are nymphs of plant parasitic Hemipterans, most probably Mealybugs in the family Pseudococcidae.
  You can use BugGuide for comparison.  It appears that is a vile Argentine Ant in attendance.  The invasive, exotic Argentine Ant will move plant parasitic Hemipterans from plant to plant, and they tend to them and protect them.  We believe the plant was damaged, and the wound provided a food source for the nutrient sucking Mealybugs.

Subject: Plagued by bugs!!

Hi there,
I live in Newcastle nsw Australia and have been plagued by bugs for the past 6 months. They are irritating my skin and my partners. We get itchy and have open sores all over our bodies, mainly just behind our ears and on the neck, legs, arms, face, back, hands and feet, well everywhere! We had pest control come and exterminate what he believed to be bird mites several types he said, funnily enough he wouldn’t come back again because he was tired and won’t take our calls now . Initially the problem died down but now 2 months later is back full force, it’s not scabies, it’s possibly a million other things but we can’t seem to find any help with this. Tonight I was in the bathroom and this long spindly legged thing appeared from nowhere, I know I have seen it several times around the house but have no idea what it is and if it could be a factor in the skin dilemma.

Unknown Hymenopteran

Possibly Red Spider Ant Alate

Dear Rachel,
We are relatively certain that the pictured insect is not responsible for your skin irritation, and we believe that Mites are most likely the problem.  The pictured insect is a member of the order Hymenoptera which includes wasps and ants.  We are leaning toward it being the alate of an Ant, a winged reproductive individual, though the legs are quite long for a typical ant.  Perhaps one of our readers will be able to provide us with a more definitive identification.  Again, we do not believe this Hymenopteran is related to your skin condition.  This individual does resemble the Red Spider Ants pictured on the Brisbane Insect website.
