Cabbage Whites

Dear Marie-Eve,
These pretty little butterflies are Cabbage Whites, a European species thought to have been introduced into North America in the 19th Century.  According to BugGuide:  “Introduced accidentally near Montreal in the 1860s, this species has become an important pest. Bacterial and viral diseases now provide some biological control.”  Caterpillars feed on cabbage and many other plants in the same family.

Found this beetle on a cut down Palm tree, as I approached him he stopped in place.
I wanted to find out what this bug is but couldn’t find anything similar.

I was out in my backyard and i seen this wet spot on my patio, i looked up and seen it was coming from a branch on my umbrella willow, i looked and went to touch it and the whole branch started moving! There were it seemed like thousands of these things on this one spot of the tree. I looked more over on both trees I have, and these things are all over both trees in several locations. Can you tell me what this is? and how to fix it maybe??
Thanks so much!

Giant Willow Aphids

Giant Willow Aphids

Hi Rich,
Though it is not a boring insect, the Giant Willow Aphid is nonetheless no beneficial on your tree.  Like other Aphids, they suck the nourishing fluids from their plant hosts.  According to BugGuide, the Giant Willow Native,
Tuberolachnus salignus, is:  “Non native, introduced from Europe around 1872. Considered a minor pest” and “According to Dr. Tilly Collins, the Giant Willow Aphid is ‘genetically incompatible with sexual reproduction and reproduces parthenogenetically year-round.'”  Many Aphids are parthenogenic or give live birth at some times, but it seems the Giant Willow Aphid must give live birth without sexually commingling its genetic code at all times.

Found these eggs attached to the aerial roots of an orchid this morning. Mid Fall and mid morning.
I have both intact and another picture where they had hatched.

Multicolored Asian Lady Beetle Eggs, we believe

Multicolored Asian Lady Beetle Eggs, we believe

Dear Constant Florida Gardener,
These sure look like the Eggs of a Multicolored Asian Lady Beetle that are posted to BugGuide.  Though they will eat Aphids, we consider the Multicolored Asian Lady Beetle to be an Invasive Exotic species that might be partially responsible for the decline in native Lady Beetle populations.  We would not rule out that they are the eggs of a native Lady Beetle.

Thank you so much for the reference and quick response.

Oriental Flower Beetle

Oriental Flower Beetle

Dear Kim,
The Oriental Flower Beetle,
Protaetia orientalis, is an introduced species in Hawaii that is considered an invasive species that feeds on fruit.  We would not rule out that it might bite, but its real threat to Hawaiians is not the threat of a bite, but the damage that is done to fruiting trees.

Lablab Bug

Lablab Bug

Dear Curious,
Introduced from Asia, the Lablab Bug or Kudzu Bug,
Megacopta cribraria, has become quite a nuisance in the South because of its large populations and because it is known to enter homes to hibernate.  According to BugGuide:  “may invade homes in large numbers and become a household pest(1); highly invasive species of mixed impact: it seems to prefer kudzu (a highly invasive and damaging plant), but can also become a serious pest of leguminous crops.”
