Solitary mining bee nests by Wendy Carter
It's spring and hopefully you've noticed the buzzing of bees and fluttering of butterflies; many of our insects are suddenly active.
Wildlife like bees, ants, wasps and some beetles find benefits from forming communities, either with one large nest or near others of the same species. Insects often do this for division of labour when rearing young - many hands (or wings in this instance!) make light work.
You're probably familiar with the colonies of bumblebees, where the workers pull together to grow the colony. Solitary bees, as their name suggests, nest alone but they often do so near hundreds of other solitary bees. Nesting in large groups increases their chances of survival; it's much harder for a parasite to target 'your' nest when there are so many others to choose from. In addition, areas with lots of bee activity might be just that bit more intimidating to predators.
Ants are famous for nesting in large communities and use complex hormones to communicate and work together to create amazing underground tunnel structures. They forage in large numbers for food or nest material that they are unable to collect as individuals.
