Saw a lot of these on a house pond with fish. Are they safe?

I found out its a mosquito larvae

Mosquito Larva

You are correct that this is a Mosquito larva.  They are commonly called Wrigglers because of the way they move through the water.  Home gardeners in California, where most gardens get frequent watering, are warned that even the smallest container of water can become a breeding ground for Mosquitoes.  It is quite interesting that the fish in the pond are not eating the Mosquito larvae.  If the fish are Koi, they might be too large to be interested in such a small creature, but introducing mosquito fish might help control the situation.

Black flying mosquito looking insect landed on my hand while i was sat in my garden. I live in salford/manchester in england. i didnt think mosquitos could survive over here

This sure looks like a Mosquito to us.  Did it bite?  The Mosquito is number four on the NHS site 12 UK Insects and Bugs that Bit or Sting.  Additionally, BBC News has a posting entitled Is the Mosquito Menace Growing in the UK?

Yes it bit me as i took a picture of it. I had a small red lump for around 2 weeks

That sounds like exactly the reaction we would expect from a Mosquito bite.  You failed to mention if it itched.

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.

Mosquito Larva

This is some type of larva, and it does remind us of a Beetle larva in the order Coleoptera.

Correction:  Thanks to a comment from Angel Robinson, we reverted to our original first impression that this is a Mosquito larva.  As sometimes happens when we are rushed, we post without any research.  We found a posting on Plankton and Macroinvertegrates of Woodland Vernal Pools that confirms the pictured larva is a Mosquito larva.

Hi bugman,
I was just stung my a mosquito and when it was bellying out on the wall, I noticed it had some white markings on its legs. I know Dengue mosquitos have this too, and I am currently also coming down with flu (slight headaches, sore throat, but no bleeding or rashes or anything). I’m living in the outskirts of Davao City in the Philippines and dengue is known to be present in this region (Mindanao).
I managed to take a few pictures of the mosquito. They’re not 100% sharp, but hopefully it will give you some clue.
I did kill the mosquito by the way. Sorry for that, I know you’re not a fan of that. Neither am I, but in the case of mosquitos (in relation to dengue) I’m not taking any chances.
Thanks in advance for your time. Hope you can identify it!

Asian Tiger Mosquito

Asian Tiger Mosquito

Dear Hugo,
In no way would we ever tag accuse a person of Unnecessary Carnage for swatting a Mosquito.  Based on this BugGuide image, we believe this is an Asian Tiger Mosquito,
Aedes albopictus, and according to BugGuide:  “The Asian Tiger Mosquito is so named because of its conspicuous stripes, ferocious feeding behavior and its Asian origin.”  BugGuide provides the following medical importance information:  “Aedes albopictus is most well known for transmitting dengue and chikungunya viruses but it has also been found infected in nature with the following viruses: West Nile, Eastern equine encephalitis, Japanese encephalitis. It can also transmit dog heartworm parasites. (CDC) Ae. albopictus is a competent laboratory vector of at least 22 arboviruses.  Ae. albopictus may have played a major role in ZIKV transmission in Gabon in 2007. (13) Armstrong et al. (2013) tested > 34,000 Ae. albopictus from New Jersey over a 3-yr period to evaluate its importance as a regional arbovirus vector.”

Hi Daniel,
Thanks for your quick reply.
I think you’re right about the Tiger mosquito. We’re all up in arms here now to keep them out and get rid of their breeding grounds, but it’s kind of baffling to me how many people don’t know (or don’t care) much about the risks and keep their doors and windows open as usual. Even after you warn them. I’ve read that the death toll was already in the hundreds nation wide around juli / august and some 80.000 diagnosed cases, which is significantly more than the year before, so it sounds like it’s quite a substantial issue. Our area was apparently designated as “dengue hot zone” in August, but we had no idea.
Well I knew it was there of course, but not like this.Yet as soon as you start a compost heap in the back yard, the neighbors will be screaming their lungs out about snakes. Still have to see the first one after six months here, but I spotted the second Aedes already today. As long as the fever stays away.. But I fear that if Zika arrives (and it seems to be on its way), the doors will literally be wide open. Not the most comforting foresight, since my girlfriend and I are in the baby making phase right now..
Anyway, I should be directing my concerns towards the department of health here, not you 🙂 Thanks for helping me ID the mosquito and best of luck with whatsthatbug. I was browsing the site a little more, and only now am I realizing what a unique and amazing project this actually is. Or more like a work of love probably, with this much effort.
Thanks again and keep it up!
All the best,

Thanks for the compliment Hugo, and good luck with your Mosquito control.

So [this] is not an Aedes albopictus, but, in fact, an Aedes aegypti.  It’s in pretty bad condition, but the lines along the edge of the scutum are typical of an aegypti.  I’ve attached a figure to show the difference.

Good morning!
I found this little guy in water on my deck. It’s about 9/16 inches long and wiggles like a mosquito larvae. Any information on this would be very much appreciated.

Mosquito Larva

Mosquito Larva

Dear Todd,
This is a Mosquito Larva, commonly called a Wriggler.  It will soon pupate into a Tumbler, a very active aquatic pupa.  With the Zika scare, Southerners are being cautioned about standing water, which is a breeding ground for Mosquitoes.  Mosquito larvae and pupae both need air to survive, and they generally congregate at the surface of the water where they can breed, but any disturbance sends them wriggling and tumbling beneath the surface for several minutes.

Thanks for getting back to me so quickly.  I had no idea mosquito larva got this large.
Although I feel a little like I wasted your time, I appreciate it, just the same.
