Initially, the DuProprio application only featured properties for sale in a list, as it was not possible for a library to display Google Maps in a mobile app in 2009. In order to create what is now a commonplace experience for users, our team developed a custom MapKit based on Google Maps Web to display the tiles of the map. We also had to add our own implementation of touch handling and native positioning of properties, because internet performance on mobile devices was terrible at the time. This shows how incredible technological challenges are sometimes hidden behind the simplest user experiences.
Centris pallida was officially discovered and catalogued by William J. Fox in 1899 near Phoenix, Arizona. Fox also discovered Centris cockerelli, Centris errans, and Sphex subhyalinus. This species is closely related to Centris cockerelli in terms of habitat and genus, but is different in terms of mating, color, and subgenus. This bee also belongs to the superfamily Apoidea, and the subfamily Apinae.
