Field of Fear

A Common Blue Roller hunting
in an abandoned lot in
downtown Courtenay.

I spotted this Common Blue Roller in almost the same location where I saw one back in the fall of 2009, suggesting that for this species there may be some strong site fidelity.

Aggressive and unpredictable, these large predatory carts should be approached with caution. Given that there are plenty of outside cats in the neighbourhood it was likely stalking cats in this field.

One more reason to keep your pets inside.

Common Blue Rollers

A herd of Common Blue Rollers.

I first encountered this aggressive, introduced cart back in the fall of 2009. Know as an ambush predator, this herd (also know as a rollback) of Common Blue Rollers was remarkably calm - perhaps it was the poor weather that had driven them to seek shelter together.

You'll find Common Blue Rollers throughout North America - look for them lurking behind dumpsters and in ditches waiting for unsuspecting prey. Caution is advised when viewing them and approaching too closely is not recommended.

Detailed natural history accounts for species of other Vancouver Island carts can be found on my personal blog Island Nature.
