This is a quite common species in Alberta around early May, whether it is swimming in a small pond or large lake, or flying over barren wastelands. This species can bite if handled badly, a correct way of holding is on on its back in a way so it can't bite you. The "Mid-sized" diving beetles are smaller than Large Diving beetles and larger than the 2-5mm ones (as its name suggests) Need more info!
