Stomach content analysis of 20 pregnant (x body mass=13.4 g) and 18 lactating (x body mass=11.5 g) female Tadarida brasiliensis revealed that the diet, expressed as percent volume, consists largely of lepidopterans, coleopterans, hymenopterans, and dipterans, in decreasing order of importance. We found no significant difference in the diet of pregnant and lactating females when expressed as percent volume. However, when expressed as percent frequency, proportionately more pregnant females fed… 
Reproductive energetics of the nectar-feeding bat Glossophaga soricina (Phyllostomidae)

  • 2003
TLDR
Examination of how nectarivorous bats respond to the energetic challenge of reproduction in pregnant and lactating Glossophaga soricina found that the reduced flight activity of pregnant bats compensated for the increased power requirements of flight, thus resulting in an almost constant daily energy turnover.
REPRODUCTIVE ENERGETICS OF CAPTIVE AND FREE‐RANGING EGYPTIAN FRUIT BATS (ROUSETTUS AEGYPTIACUS)
TLDR
It is concluded that the energy costs of Egyptian fruit bats during reproduction are distributed over a relatively long time, similar to those observed in large mammals.
Changes in milk composition during lactation in three species of insectivorous bats
TLDR
Comparison of the effect of sampling method on milk composition of T. brasiliensis indicated that fat, dry matter, and energy concentrations increased significantly from pre-dawn to prenoon samples, which may reflect the limited access that lactating females have to free water, as well as need to minimize mass of stored milk during long foraging trips.
Quantitative evaluation of individual food intake by insectivorous vespertilionid bats (Chiroptera, Vespertilionidae).
TLDR
The novel method for the estimation of insects' biomass consumed by bats is offered, which estimates the amount of insects consumed by free-ranging bats based on dry mass of their feces.
Quantitative evaluation of individual food intake by insectivorous vespertilionid bats (Chiroptera, Vespertilionidae)
TLDR
The novel method for the estimation of insects’ biomass consumed by bats based on dry mass of their feces is offered, which confirms the importance of insectivorous bats for ecosystem services.
Dietary energy estimate inferred from fruit preferences of Cynopterus sphinx (Mammalia: Chiroptera: Pteropodidae) in a flight cage in tropical China
From a conservation standpoint, inferences about dietary intake are much more robust when placed within a demographic, temporal and nutritional context. We investigated the dietary cornerstones of
DIET OF FLAT-HEADED BATS, TYLONYCTERIS PACHYPUS AND T. ROBUSTULA, IN GUANGXI, SOUTH CHINA
TLDR
Food habits of Tylonycteris pachypus and T. robustula were examined by fecal analysis in 2 counties of Guangxi, South China, showing clear seasonal variation from spring to autumn and differences in diet between the different geographical areas studied.
FOOD HABITS OF NYCTINOMOPS MACROTIS AT A MATERNITY ROOST IN NEW MEXICO, AS INDICATED BY ANALYSIS OF GUANO
TLDR
This study documents an unusually varied diet, as previous studies indicated that big free-tailed bats fed almost exclusively on moths.
DIETARY VARIATION OF BRAZILIAN FREE-TAILED BATS LINKS TO MIGRATORY POPULATIONS OF PEST INSECTS
TLDR
Food habits of Brazilian free-tailed bats at 3 colonies in central Texas over 3 summers suggest that crop pests comprise a substantial portion of the bats' diet and that bats provide valuable natural pest control services.
VARIATION IN DIET OF THE MEXICAN FREE-TAILED BAT (TADARIDA BRASILIENSIS MEXICANA)
TLDR
The diet of Mexican free-tailed bats at Carlsbad Caverns National Park is documents, and information on seasonal variation in food habits of this species throughout its summer residence is provided.

Energetics of Pregnancy and Lactation in Freeranging Little Brown Bats (Myotis lucifugus)
TLDR
The large amount of energy devoted to foraging by this aerial-feeding bat may partially explain the low proportion of energy it allocates to tissue production and milk export.
Feeding Strategies of the Little Brown Bat, Myotis Lucifugus, in Southern New Hampshire
TLDR
It is suggested that increased resource availability allowed selective feeding in adult bats during July, as predicted by presy selection models, however, reduced discriminatory abilities may prevent similar levels of prey selection in juveniles.
Energetics and Water Flux of Free-Ranging Big Brown Bats (Eptesicus fuscus) during Pregnancy and Lactation
TLDR
Using doubly labeled water to measure carbon dioxide production and water flux during pregnancy and lactation in free-ranging big brown bats, Eptesicus fuscus, it is calculated that the average requirement for assimilated energy was 48.9 and 105.1 kJ/day for pregnant and lactating females, respectively.
Water balance of free-ranging little brown bats (Myotis lucifugus) during pregnancy and lactation
This study provides the first measurements of daily water flux in free-ranging bats during pregnancy and lactation. We used the wash-out rate of tritiated water from the body water pool to calculate
Feeding Ecology of a Temperate Insectivorous Bat (Myotis Velifer)
TLDR
Emigration of males from nursery colonies in late spring and early summer and emigration of adult females soon after young were weaned may provide a mechanism to reduce competition for available food.

TLDR
Foraging time increased between early lactation and fledging and then declined as the young became independent, suggesting that maximizing energy intake throughout lactation may not be the optimal strategy because storing excess energy increases flight cost and may reduce foraging efficiency.
Structure and Function of the Kidney and the Water Balance of Desert Bats
TLDR
The present study examines the water relations of three species of bats whose distributions include the hot Sonoran Desert of North America and suggests that some species may possess interesting physiological mechanisms for conservation of water.
BODY BUILDING BY INSECTS: TRADE-OFFS IN RESOURCE ALLOCATION WITH PARTICULAR REFERENCE TO MIGRATORY SPECIES
TLDR
Detailed study of four species of presumed migratory noctuid moths indicated that the larvae retain the ability, when starved from various days in the last larval stadium, to pupate and metamorphose into adults, an adaptive response producing individuals with low wing loading ratios that presumably exhibit less energetically costly flight.

TLDR
Under natural conditions arid-adapted species drink when water is available; however, indirect evidence suggests that some may be able to survive long periods without water.

TLDR
Comparisons of the kinds and numbers of insects ingested with the populations of insects present near the feeding bats suggest that M. lucifugus can be highly selective in its hunting.
