<\/span><\/div><\/div><\/div><\/div>This is the time of the year that “midges” are as thick as flies on you-know-what <\/em>at the Bear River Migratory Bird Refuge<\/a><\/span>. They are so thick that they can look like tornadoes along side of the auto tour route as seen in the image to the left. A lot of people mistake midges for mosquitoes; they do look similar, and think that they will be bitten by the swarms of bugs in the air. There are biting and non-biting midges, biting midges are often called “no-see-ums” and truly they are miserable to get into because even though you can barely see them the bites let their presence be known.<\/p>\nThe midges at Bear River Migratory Bird Refuge along the auto tour route are non-biting midges<\/em> and they play an important role in the areas ecosystem.<\/p>\nMidges have three stages in their lifetime, larval, pupal, and adult. In the larval stage midges are aquatic, they feed on algae, plankton, and small aquatic plants. They are a food source in the larval stage for fish and their appearance is similar that that of mosquito larvae.<\/p>\n<\/div>

<\/span><\/div><\/div><\/div><\/div>The female midge lays her eggs either on the water surface or on vegetation near the water. The eggs hatch in approximately 72 hours followed by a two day pupation before rising to the surface as adults. An important thing to remember is that the flying adult midges do not eat and have a short life span of about 10 days.<\/p>\n
You can hear a humming sound with that many midges in the air though they do not have the typical “buzz” a mosquito has. Midges over winter in the larval stage in the water. The midges at Bear River Migratory Bird Refuge seem to be concentrated along the sides of the dirt road of the auto tour route hovering above the grasses, or on the vegetation along the road, or nearby shoreline plants.<\/p>\n
They can be a bother when you are driving along with your windows open for birding, bird photography, or sightseeing. The outside and inside of the vehicle will literally have hundreds, if not thousands of midges attached to the interior and exterior. Not to worry though; if you leave the windows open a bit when you reach the paved road and higher speeds most will leave the vehicle.<\/p>\n<\/div>

<\/span><\/div><\/div><\/div><\/div>They do tickle if they land on your skin and the sheer numbers of them can feel a bit overwhelming but they don\u2019t bite.<\/p>\n
They are; however, an important food source for many of the birds found on the refuge. The midges at Bear River MBR first appear around March or April and are often still being seen through June.<\/p>\n
Many of the shorebirds found at the refuge begin to return about the time the midges are \u201chatching\u201d in the spring. They are a favorite of Eared Grebes and quite a few other birds. I have many images where the midges are either present on the water surface or are in flight around the birds I photograph.<\/p>\n
They can be troublesome to \u201cclean\u201d off the water surface and they can appear to be dust bunnies (aka sensor spots) in an image frame. Yesterday I could see one walking on my lens through the viewfinder, if that happens to you just blow it out, don\u2019t try to smoosh it or your lens will get dirty!<\/p>\n<\/div>
