“…Such tradeoffs may be especially clear during biological invasions, because of differences in evolutionary forces at the invasion front versus in long-colonised areas 2 . Individuals at an expanding range edge often exhibit unusually high rates of dispersal 3,4 , requiring energy that may decrease allocation of resources to other functions such as immune defence 5-7 and reproduction [8][9][10][11] . The increased allocation to dispersal is exacerbated by the non-adaptive process of spatial sorting; individuals that allocate more energy into dispersal will likely be close to the range edge, even if more rapid dispersal does not enhance fitness 12 .To test these ideas, we need to compare attributes of individuals at an expanding invasion front to conspecifics in longer-colonised areas.…”

“…It has been suggested that for ants, for example, queens experience a reproduction‐dispersal trade‐off that determines nutrient acquisition and storage patterns and ultimately body size (the Found of Fly hypothesis; Helms & Kaspari, ). Larger queens have a higher chance of success during colony initiation but must bear a large drag and exposure to predation during flight leading to the evolution of flightlessness in many ant species (Holldobler & Wilson, ; Helms & Kaspari, ).…”

“…Individual movement may affect population spatial structure and geographical distribution; for invasive species, dispersal can explain the rate of spread into new areas (Liebhold et al ., ; Lavandero et al ., ). This is likely why there is a growing interest in understanding dispersal behavior and flight capability of invasive insect species (Hasting et al ., ; Gilbert & Liebhold, ; Bigsby et al ., ; Helms & Kaspari, ).…”

“…In contrast, claustral queens accumulate metabolic reserves that make it unnecessary to go outside the nest. Enlarged wing muscles are required to carry bigger protein and fat reserves during flight (Helms & Kaspari, 2015), and these muscles are later broken down and resulting amino acids fed to the first larvae. Importantly, reversal to non-claustral ICF has been documented in at least 12 genera of Myrmicinae and two genera of Formicinae, a total of 28 species (reviewed in Brown & Bonhoeffer, 2003;Hahn et al, 2004;Keller et al, 2014).…”
