COVER PHOTO : The cover photo shows an individual of the bumble bee Bombus perplexus foraging on an Echinacea flower in Ipswich, Massachusetts, USA. Elshoff et al. ( Ecology , Volume 107, Issue 4, Article e70385; doi: 10.1002/ecy.70385 ) studied how the phenologies of this and thirteen other eastern North American bumble bee species changed in response to spatiotemporal climate variation. The authors found that B . perplexus , like most of the other species in their study, both began and ended its flight period earlier in the year in warmer conditions. Unlike most other species, however, its flight period also appeared to shorten under these conditions. Photo credit: Kyle C. Elshoff. image
