Arthropod molting hormones (ecdysteroids) are present in the blood of insectivorous bats

In this study, blood samples of eight insectivorous bat species were analyzed for the presence of ecdysteroids with highly sensitive targeted ultra-high-performance liquid chromatography coupled to high-resolution quadrupole-orbitrap mass spectrometry method (SIM). Nine ecdysteroids were detected in bat blood.
