Rains beginning June 19 have kept water levels high throughout much of east central Illinois. Flooding throughout cities has been significant. Low lying areas within rural fields have remained flooded throughout much of this period. Many of these areas have become major mosquito breeding grounds. Fortunately the last few days have brought relief from the rains. Record low temperatures have slowed the rate of mosquito development considerably.
The temporary pond I began observing June 20 has remained throughout this entire time period. It now supports large numbers of aquatic beetles, dragonflies, damselflies, and freshwater crustaceans, in addition to the amphibians I’ve been documenting. Mosquito larvae make up a large part of the diet of many of the predaceous insects.
Our ditch, suddenly flooded and lacking a significant number of predators, became an area of significant mosquito breeding after last weekend’s rains. The water level dropped significantly last night. This four image set documents changes that occurred within that ditch over the last eighteen hours. Click each image for maximum viewing pleasure!
