In Austin, Texas, a colony of Mexican free-tailed bats summers (they winter in Mexico) under the Congress Avenue Bridge 10 blocks south of the Texas State Capitol. It is the largest urban colony in North America, with an estimated 1,500,000 bats. [38] Each night they eat 10,000 to 30,000 lb (4,500 to 13,600 kg) of insects.
An often-mentioned statement is that "bats can eat 1000 mosquitoes per hour." [37] [38] [39] While the little brown bat does consume mosquitoes and has high energetic needs, the study that is the basis for this claim was an experiment in which individuals were put into rooms full of either mosquitoes or fruit flies.
Bats in Indiana were found to prefer beetles, moths, mosquitoes, midges, leafhoppers, and wasps. [50] Other arthropod groups which are consumed by Indiana bats in very limited quantities are lacewings (Neuroptera), spiders (Araneae), stoneflies (Plecoptera), mayflies (Ephemeroptera), mites and ticks (Acari), and lice (Phthiraptera).

Insectivorous bats may eat over 120 percent of their body weight per day, while frugivorous bats may eat over twice their weight. [148] They can travel significant distances each night, exceptionally as much as 38.5 km (24 mi) in the spotted bat ( Euderma maculatum ), in search of food. [ 149 ]
A 2011 study of a population in Colorado found that their average life expectancy was a little over 6.5 years; [43] according to a 2008 report, some banded big brown bats have lived up to 20 years, although some experts have hypothesized that the bats might be "capable of living much longer."
They typically fly straight and relatively fast for bats; some species are slower with greater maneuverability. Species can commute 20–50 km (12–31 mi) in a night. Migratory species of the genera Eidolon , Pteropus , Epomophorus , Rousettus , Myonycteris , and Nanonycteris can migrate distances up to 750 km (470 mi).
Symptoms of climate change which include milder winters and early springs are giving mosquitoes and ticks more time to reproduce, spread diseases, and expand their habitats throughout the United ...
Ticks do not use any other food source than vertebrate blood and therefore ingest high levels of protein, iron and salt, but few carbohydrates, lipids or vitamins. [47] Ticks’ genomes have evolved large repertoires of genes related to this nutritional challenge, but they themselves cannot synthesize the essential vitamins that are lacking in ...
