Globemallow Leaf Beetle - Calligrapha serpentina 
The Globemallow Leaf Beetle may look like a type of Lady Bug, bit it is not. As a member of the leaf beetles family (Chrysomelidae) the diet of Calligrapha serpentina is plant-based, unlike the carnivorous diet of Lady Bugs. In fact, many leaf beetles are considered pests due to the extensive damage they inflict on the plants they are eating. 
As its common name suggests, the preferred vegetation of Calligrapha serpentina are plants in the mallow family, specifically the bushy, bright, desert-growing Globemallow.
This species occurs in the southwestern of the United States and Mexico.

Eudiagogus pulcher
…a species of Sesbania Clown Weevil (Eudiagogus spp.), a group of Broad-nosed Weevil (Entiminae). E. pulcher occurs from southern North America and Mexico south to Central America. Adult E. pulcher are typically seen in wetland margins and are known to feed on the foliage of rattlebox (Sesbania spp.). Their larvae will feed on rattlebox as well but instead of foliage will feed on the root nodules of rattlebox.

Lately, here in Houston, TX, I’ve noticed that the Green June Beetles (Cotinis nitida) are flying all of the place again. This seems to happen every year in late Summer/early Fall. I found this fine little lady crawling around on an American Beautyberry.

This species is a kind of “flower chafer”, so named because the adults commonly feed on the nectar and pollen of flowers. In this area, the species is often associated with Magnolias. They are found through out the SE United States and into Northern Mexico.

Banded Cucumber Beetle - Diabrotica balteata 
This beautiful beetle belonging to the species Diabrotica balteata (Coleoptera - Chrysomelidae) is a well known pest of many crops in Mexico, the United States and Central America. Adults are distinctive for their bright green color and by having two transverse bands on elytra, each with four irregular yellow spots.

"Filbert Weevil" (Curculio occidentis)
…a species of ‘acorn weevil’ (Curculio spp.) which is recorded occurring in California and surrounding areas. Filbert weevil larvae are noted for feeding on a variety of oak tree species. This has caused them to be regarded as a major pest due to the damage they cause to acorns.

Common European Cockchafer - Melolontha melolontha

Also referred to as Maybug and Field Cockchafer, Melolontha melolontha (Coleoptera - Scarabaeidae) is a common inhabitant on agricultural lands throughout temperate Europe and the United States.

Males Common European Cockchafers have longer antennae than females, with a large, fan-like club protruding.

Cockchafers are among the most dreaded insect pests in many European countries, causing economic losses in agriculture, horticulture and forestry. In forests of south-western Germany, populations of the Forest Cockchafer (Melolontha hippocastani) and also the Field Cockchafer (M. melolontha) have been increasing during the past three decades and, therefore, monitoring of these populations has been intensified.

Tiger Beetle (Cosmodela aurulenta)

family Cicindelinae

The tiger beetles are a large group of beetles known for their aggressive predatory habits and running speed. The fastest species of tiger beetle can run at a speed of 9 km/h (5.6 mph), which, relative to its body length, is about 22 times the speed of former Olympic sprinter Michael Johnson,the equivalent of a human running at 480 miles per hour (770 km/h).
They live along sea and lake shores, on sand dunes, around lakebeds and on clay banks or woodland paths, being particularly fond of sandy surfaces. Tiger beetles are considered a good indicator species and have been used in ecological studies on biodiversity.

Asian Multi-spotted Ladybird Beetle (Harmonia axyridis):

The first photo set shows the variety in coloration and spotting, bit what stays the same are the large white edge spots on the sides of the pronotum (thoracic shield).  (photo by ©entomart)

The second set shows the full life cycle of H. axyridis. (photo by puddingforbrains).

This species has been widely introduced, purposefully, into Europe and North America, as garden pest control. This has had a deleterious effect on several of our native lady bird beetle (“ladybugs”) species, as native species are often unable to compete with the voracious predator of scales and aphids.

In the United States, we do have several species of native Ladybird Beetle. Find out more here:

Milkweed Leaf Beetle (Labidomera clivicollis)

For the past couple of weeks, I’ve noticed a new visitor to the Milkweeds, in the herb garden at the nature center (where I work, Houston, TX). Living along side various aphids, ladybird beetles, monarch butterfly caterpillars is this gorgeous little yellow phase Milkweed Leaf Beetle (they are more commonly red and black, or even orange and black). This beetle is associated with a few species of milkweed across North America, which they feed on, by first draining some of the poisonous sap at the base of the leaf with a well placed cut.

Bee Beetle - Trichius gallicus 
This hairy beetle resembling a bee is an European species of the Scarabaeidae Family, scientifically named Trichius gallicus [Synonym: Trichius rosaceus], and commonly referred to as Bee Beetle due to its coloration pattern and because it buzzes like a bee when it flies.

Beetle ID - BC, Canada:
Possible ID, please? :) Found in Vernon, British Columbia, Canada.
Paxon:
Yes absolutely. This is a Knapweed Root Weevil (Cyphocleonus achates), family Curculionidae. They are native to Europe, and were introduced into North America to help control invasive Knapweed.
