Little or no data is accessible on the beetle pictured right here. The Mosaic Spherical Sand Beetle (Omophron tessellatum) is taken into account widespread all through a lot of the United States and far of Canada as properly. I have been photographing and gathering bugs for over a decade now and this 12 months was the primary I’ve ever encountered this species.
I had positioned a white sheet and mercury vapor gentle close to our creek and an outdated farrowing home. One evening whereas checking the sheet I seen an insect on the bottom shifting quickly in circles on the bottom in some tender loamy dust. It was such odd, erratic habits for an insect it caught my consideration instantly. I watched it for a while earlier than it occurred to me to catch it and attempt to determine it. It proved considerably tough to catch because it ran shortly underneath the dust and scurried away. After a number of tries I used to be capable of seize it and ID’d it because the Mosaic Spherical Sand Beetle. There are quite a few beetles inside this genus, with most of them positioned within the Northern Hemisphere. Examples of beetles inside this genus could also be present in North America, South America, Asia and Africa.
These sturdy burrowers are usually present in sandy areas close to creeks, lakes and different water sources, which might clarify its presence on the white sheet close to the creek. Just a few species inside this genus could also be interested in lights at evening and apparently that is certainly one of them. I’d assume these are the industrious hunters as they feed on bugs each within the grownup stage in addition to the larval stage. With all method of bugs being attracted by the mercury vapor gentle it was an all-you-can-eat-buffet for these evening time hunters.
Their sturdy mandibles remind me of the jaws discovered on tiger beetles and seem like they might trigger some critical injury to unsuspecting insect prey. They’ve massive bulbous eyes which I assume offers them good eyesight for recognizing prey, and with the velocity at which they transfer, catching a shifting goal would not be too tough.
It’s assumed they spend the winter within the grownup stage hiding amongst leaf litter in addition to different protected areas. Within the spring mating happens, however I may discover no data on the place younger are reared or how lengthy it takes for them to finish their lifecycle.
At solely 5-7 mm in size, they show that typically essentially the most fascinating issues are available small packages.
