Aedes cataphylla is a mosquito found in Utah. Larvae occur mainly in open snowmelt pools in mountainous and subalpine areas above 7,000 feet, but can be found at lower elevations in mountain valleys or foothills. Larvae have been collected as early as February in lower elevations!

It may be the first of December, but winter is the perfect time to go through your old photos. Join our iNaturalist project page "Mosquitoes of Utah" to follow along, upload your mosquito photos, & help ID submissions! iNaturalist is free to join, head to iNaturalist.org to create your account! 🦟

The mosquitoes that carry dengue and other dangerous diseases wouldn’t have been able to survive in Colorado before. Now they’re thriving in one community as temperatures warm.

We want to give a huge thank you to each & every one of you who attended, presented, & supported the 77th annual UMAA Conference last week! Thank you to the sustaining members & sponsors of the UMAA! We appreciate all of our members & those who make events like this possible. See you next year!

Iceland, one of the last places on Earth to be mosquito-free, recorded its first sighting this month. Scientists say warming is making the country more hospitable to the insects.

WNV updates from across the state for human (48) & horse (21) cases. Recent & past reports: epi.utah.gov/west-nile-vi... & mosquito positive samples: maps.vectorsurv.org/arbo (link in bio). Take preventive measures against mosquito bites. There are also vaccines for horses for West Nile virus!

The UMAA annual meeting starts on October 27 and goes to October 29! We are officially less than one month away. 🦟 Utah MADs: make sure you're registered and have your hotel accommodations made. We'll see you in Park City!

Mosquito abatement districts across Utah use Integrated Mosquito Management, or IMM. IMM uses a combination of methods to help reduce mosquitoes. Check out this page on the CDC website to learn more about it! www.cdc.gov/mosquitoes/p...

Use these suggestions to reduce and avoid #mosquito bites! There have already been 28 human cases of West Nile virus this mosquito season so be sure you're protecting yourself. Share with your friends & family to prevent bites. 🦟

West Nile virus updates from across the state for human & horse cases. You can find the recent & past reports here: epi.utah.gov/west-nile-vi... & mosquito positive samples: maps.vectorsurv.org/arbo. Wear an EPA approved insect repellent and cover up exposed skin to prevent mosquito bites!

Two county health departments in Utah are reporting more human cases of West Nile virus on Wednesday, including one that led to the death of a Davis County resident.

Mosquito abatement districts in Utah, including SLCMAD, have been detecting recent positive mosquito samples of St. Louis encephalitis virus (SLEV). It is not new to the U.S., & has been detected in Utah before. Like WNV, there is no vaccine to prevent SLEV. Remember to prevent mosquito bites! 🦟

The Salt Lake County Health Department announced today the first human case of WNV in Utah this year. Public health's investigation has determined they were likely infected in late July near the Jordan River in the southern half of Salt Lake County. www.saltlakecounty.gov/health/news/...

Check out the items highlighted in yellow. Do you have any of these around your property? If so, you may want to check 'em out for standing water! Mosquito larvae require standing water in order to survive and grow.

Mosquitoes have four stages of their life cycle and the first three take place in the water. It's important to remember to check your property for standing or stagnant water at least once a week to reduce mosquitoes!

Utah has many mosquito abatement districts (MAD) across the region. Check out umaa.org to find your local MAD and check out AMCA's new website, Yesterday's Threat Today's Solution to find more mosquito prevention information.

It's the last day of February! Spring is around the corner, and soon mosquitoes will be, too. 🦟 Be proactive and be prepared to prevent mosquito bites once the weather gets warmer. ☀️ #mosquitoprevention #mosquitobiteprevention

Join SLCMAD on Thursday, 2/27, for the groundbreaking ceremony of the District's Phase II development! Groundbreaking begins at 11:30 am, refreshments will be provided. 🦟

Many of the Utah districts attended the West Central MVCA joint meeting with the Wyoming Mosquito & Vector Control Association last week! Participating in these meetings are valuable and allow different regions to come together to continue improving vector programs and protect public health.🦟

The West Central Mosquito & Vector Control Association + Wyoming Mosquito Management Association are combining forces this year for their annual meetings! Taking place at the Snow King Resort in Jackson, WY from February 19-20; learn more here: www.wcmvca.org.

New publication from SLCMAD! "Managed #honeybees, Apis mellifera (Hymenoptera: Apidae), face greater risk from parasites and pathogens than #mosquitocontrol #insecticide applications" is open access in the Science of The Total Environment. Find it here & please share: doi.org/10.1016/j.sc...

Our colleagues at PacVec have included an update in their newsletter from the CDC regarding dengue and Oropouche viruses. For those traveling, remember to take preventive measures like wearing insect repellent and covering up exposed skin.
