ClimaciaBlack-light sessions in late August and early September along the South Skunk River resulted in collection of several adult spongillaflies (Sisyridae: Climacia areolaris). These presumedly “rare” insects had never been recorded from central Iowa (in fact, they were previously known only from extreme NE Iowa).

Based on recent findings from the state mosquito surveillance program run by Assistant Professor Ryan Smith and in close collaboration with the Iowa Department of Public Health, there have been high levels of WNV activity in mosquito populations in Central Iowa. To date there have been 30 human cases of WNV in Iowa (including 3 deaths) and are currently on pace to have the highest number of cases of WNV in the state since 2003.

As humanity experiences relentless pressures from disease-carrying mosquitoes in many parts of the world, there is an urgent need for new tools to use against those beasts – because they keep getting scarier.

Even though DEET remains the most commonly used, and most powerful, mosquito repellent ever developed, scientists are actively pursuing effective products based entirely on plant oils, some tracing their roots to traditional remedies.

BOSTON, Aug. 20, 2018 — Nearly 700 million people suffer from mosquito-borne diseases — such as malaria, West Nile, Zika and dengue fever — each year, resulting in more than 1 million deaths. Increasingly, many species of mosquitoes have become resistant to the popular pyrethroid-based insecticides. Today, researchers report a new class of mosquito repellents based on naturally occurring compounds that are effective in repelling mosquitoes with potentially fewer environmental side effects than existing repellents.

Brown recluse spiders have been found in Iowa but they remain rare.  And since they are reclusive (hence the name!) bites by BRS (and all spiders!) are not common.  But BRS is a frequent misdiagnosis for other skin irritations.  And to be clear, they are not the cause of human limb amputations.

This is not about insects, but since earthworms "crawl" that's close enough to entomology for most people.  Asian jumping worms were recently confirmed in Iowa for the first time.
