Dear Lisa,
This is a Mosquito and your couch is not a Geographic Location.  According to Sciencing:  “Geographic location refers to a position on the Earth.”  Your couch might be in Alabama or it might be in Zanzibar.

Facebook Posting from Paula Di:  I’ve never seen a mosquito that looks like this! What part of the world is this from? Thank you

It’s on a couch.  More than that is pure speculation.  Ed. Note:  That is no dig to Paula Di, but rather support of the need for actual geographic locations to assist in our identification process.

Yellow Fever Mosquito, we believe

Dear Robin,
We are sorry to have to bear bad news, but this sure appears to be one of the invasive disease carrying Mosquitoes in the genus
Aedes.  We believe, based on this BugGuide image, that it is the Yellow Fever Mosquito, Aedes aegypti, which is described on BugGuide as being a: “Medium-sized blackish mosquito easily recognized by a silvery-white ‘lyre-shaped’ pattern of scales on its scutum.”  According to BugGuide:  “the most important and efficient epidemic vector of dengue viruses, has been in the United States for over 200 years and was responsible for transmitting major epidemics in the southern states in the 19th and early 20th centuries.  The female mosquitoes are very nervous feeders, disrupting the feeding process at the slightest movement, only to return to the same or a different person to continue feeding moments later. Because of this behavior, A. aegypti females will often feed on several persons during a single blood meal and, if infective, may transmit dengue virus to multiple persons in a short time, even if they only probe without taking blood. It is not uncommon to see several members of the same household become ill with dengue fever within a 24- to 36-h time frame, suggesting that all of them were infected by a single infective mosquito. It is this behavior that makes A. aegypti such an efficient epidemic vector. Inhabitants of dwellings in the tropics are rarely aware of the presence of this mosquito, making its control difficult.”  According to the California Department of Health:  “Two invasive (non-native) mosquito species have recently been found in several California cities …, and there is a potential for them to spread into other areas of California. They are named Aedes aegypti (the yellow fever mosquito) and Aedes albopictus (the Asian tiger mosquito). Unlike most native mosquito species, Aedes aegypti and Aedes albopictus bite during the day. Both species are small black mosquitoes with white stripes on their back and on their legs. They can lay eggs in any small artificial or natural container that holds water.  Aedes aegypti and Aedes albopictus have the potential to transmit several viruses, including dengue, chikungunya, Zika, and yellow fever. None of these viruses are currently known to be transmitted within California, but thousands of people are infected with these viruses in other parts of the world, including in Mexico, Central and South America, the Caribbean, and Asia. The presence of Aedes aegypti and Aedes albopictus mosquitoes in California poses a threat that Zika, dengue, and chikungunya viruses can be transmitted in infested areas from returned infected travelers. Travelers can protect themselves by preventing mosquito bites. When traveling to countries with dengue, chikungunya, or Zika, use insect repellent, wear long sleeves and pants, and stay in places with air conditioning or with window and door screens. ”  It is important to stress that though these Mosquitoes are present in California, they need to be infected to transmit diseases.  Since the diseases themselves have not been reported in California, the bites you are experiencing will not give you the disease, but nonetheless still result in the itchy welt that appears with most Mosquito bites.

Presumably Yellow Fever Mosquito

Ed. Note:  We noticed this Facebook comment from Richard Schroeder “According to the news, San Diego county has a large number of black salt marsh mosquitoes right now” and we decided we needed additional research.  The San Diego Union-Tribune website and other sources documented a 2009 outbreak of Black Salt Marsh Mosquitoes and images on BugGuide (which does not report the species from California) look similar to the Mosquito pictured in this submission, so the jury is still out on the actual identity of the pictured Mosquito.

Thanks to Cesar Crash for confirming our original identification.

Your letter to the bugman:  Hello Bugman! As it’s summer we set up a blow up pool in our back yard and today as I was having a dip I saw multiple tiny little wormy bugs aggressively writhing around in the water. I started feeling slightly itchy on my back so freaked out and jumped out, but I managed to grab one of the little guys and take a photo (sorry about the quality my iPhone struggled to get a clear photo).  I also have redness around where I’m itchy but I could just be paranoid and it have been a mosquito. If you could let me know what bug this is I would very much appreciate it 🙂

Wriggler: Mosquito Larva

Dear Jess,
This is a Mosquito Larva, commonly called a Wriggler.  The female Mosquito lays her eggs in a floating raft, and the young quickly hatch and develop, molting and growing, and the exact time depends on the temperature.  Controlling aquatic Mosquito Larvae is the best way to reduce the numbers of flying, and biting, Mosquitoes.

Hi! The weirdness of this situation compelled me to look online for information. This tiny little creature was found in the cistern water of a toilet that had been unflushed for a while. I apologise profusely for the blurry nature of the photos but as you can see from the mm markers it is a tiny little thing, and I took its photo through a magnifying glass with my phone. Thank you 🙂

Mosquito Larva

Dear Curiously Confused,
This looks like an aquatic Mosquito larva or pupa, or some other immature stage of a Fly to us, so finding it in an unused toilet makes sense, but it is puzzling there was only one.  The Department of Medical Entomology site has some images.

Male Gallinipper

Dear Alane,
We believe this large male Mosquito is a Gallinipper,
Psorophora ciliata, based on this BugGuide image.  According to BugGuide:  “The word gallinipper originated as a vernacular term in the southeastern US referring to ‘a large mosquito or other insect that has a painful bite or sting’ and has appeared in folk tales, traditional minstrel songs, and a blues song referencing a large mosquito with a ‘fearsome bite’ (McCann 2006)” and “one of the largest mosquitoes in the U.S. Not known to vector any mosquito-borne pathogens.”  We are postdating your submission to go live to our site later in the month when our editorial staff is away for the holidays.

I have never seen this bug before. Looks like its wearing a combination feather duster/ trident on its head and I just can’t even.

Close-up of head of a male Dipteran

Dear Kathleen,
These images are positively puzzling.  This is a member of the order Diptera, and the feathery antennae indicates it is a male, but the “trident” head anatomy is quite the mystery for us.  It is a member of a group BugGuide identifies as “‘Nematocera’ (Non-Brachycera)” that can be identified by “The most distinctive identification feature is the antennae which have 6 or more segments. Most have long and slender antennae, which in some families can be highly plumose. Other families have short, thick antennae (eg. the march flies – Bibionidae). Most of the flies in this group have slender bodies and long, narrow wings.”  This group includes Crane Flies and Mosquitoes.  We have not had any luck with our initial attempt at a species identification, and we are running out of time this morning, so we are posting it as unidentified and we will contact Eric Eaton for his input.  Meanwhile, perhaps one of our readers will be able to research this while we are out gainfully employed and working a 13 hour Thursday.  How big was it?

Male Dipteran with unusual anatomy

Update:  Eric Eaton responded to us pretty quickly “Male mosquito.  Pretty standard anatomy for them, actually.” and we found similar anatomy in this BugGuide image.
