Bumblebee removal occurs when bumblebees come in contact with the anthers of a flower while collecting nectar. When it enters a flower, the bumblebee's body hairs receive a dusting of pollen from the anthers. In queens and workers this is then groomed into the corbiculae (pollen baskets) on the hind legs where it can be seen as bulging masses that may contain as many as a million pollen grains. Male bumblebees do not have corbiculae and do not purposively collect pollen. Bumblebees are also capable of buzz pollination, in which they dislodge pollen from the anthers by creating a resonant vibration
The Grains of Sand in early 1966. Around the same time, the Rockin' Bugs agreed to change the group moniker to the Grains of Sand, inspired by a pair of college students studying chemistry while the band members proposed possible alternatives. The Grains of Sand entered Golden Star Studios in Hollywood to record "That's When Your Happiness Began", a catchy pop tune written by the Addrisi Brothers, along with the fuzz-tinged Hodgkins-original "She Needs Me". Session musician Hal Blaine took part in the recording of "That's When Your Happiness Began", which was released, coupled by "She Needs Me" as its B-side, in February 1966.
