Hi, I found lots of these climbing on my apple tree. There was also a type of white fungus around which some of them congregated – this possibly contains eggs?
I don’t know if they are bad for the tree or not. They measure approx. 1cm, but some are slightly smaller. They have 6 legs but the back part of their body looks like a caterpillar.
I hope you can help.

Dear Barbara,
While there is a pest problem on your apple tree, nature seems to be controlling the situation.  What you have mistaken for fungus or eggs is actually a type of Hemipteran, possibly a Woolly Aphid which you can read about on the Royal Horticultural Society site.  The crawling insects are the larvae of Lady Beetles, and they are feeding on the Hemipterans.   The bad news here is that the Lady Beetle Larva is an Asian Lady Beetle Larva, a nonnative species, and it is believed that the proliferation of nonnative Asian Lady Beetles in North America is contributing to the decline in numbers of native species.

Hi Daniel,
Thank you so much for the information – so it is good news and bad news!
Since posting, many of the larva have now attached their back ends to the tree bark and are hanging upside down, obviously in preparation for their next stage of development.  Also, there is now very little evidence of the ‘white fluff’ so they have probably done their job.  Unfortunately, many of the leaves on the tree are not looking very healthy but I am loathe to spray anything and just let nature take its course so I can review the tree in the autumn (it is past its prime anyway).
Thank you again for your help.
Regards
Barbara

Bugman, I was sitting on a chair in the yard of our farmland in southwest Virginia when I noticed this bug on my knee. He moved slooooowly and his feet were really stuck to my pants. I’ve never seen this kind of bug before. What is it?

Treehopper

Treehopper

Dear Lilli,
This is some species of Treehopper in the family Membracidae, and many members have spinelike or leaflike protuberances on their dorsal surfaces that help to camouflage them when they are feeding on plants.  The closest match we could find on BugGuide is this image of
Helonica excelsa.

Today, 05/18/05, I took this picture on a tree in Washington, DC. I thought they were spiders at first, and then I noticed that a couple have wings! I’ve done a ton of internet research and I can’t find anything like them. Please help!

Giant Conifer Aphids

Giant Bark Aphids

These are Giant Bark Aphids, Longistigma caryae, the largest Aphids in North America.

Oh my god, thank you SO much!!!  They sure are! :)

As an unrelated aside, we learned this morning while watching CNN that the popular internet initials OMG have another meaning.  The report on the Waco, Texas melee refers to the Outlaw Motorcycle Gangs as OMG.

Hi! In the last month I’ve discovered these little gray bugs on my fig tree & succulents nearby. They are quick, and hide so as to not to be seen. They squirt a liquid out at you, it seems…or maybe they just happen to when I’m observing them. Now I see that some of them have started molting. They look like a cool aquatic creature and I’m very curious as to what they are!

Sharpshooter Nymph

Hi Alicia,
This is the nymph of a Sharpshooter, a Leafhopper in the subfamily Cicadellinae, but we are unable to provide you with a species identification.  Perhaps if you get any images of a winged adult Sharpshooter once it matures, we will have better luck.

Mr. Bugman
I’m a photographer from Ecuador South America, I love taking nature pics in remote places in my country, since a couple years back I benn exploring the field of macro photography, and on a travel I found this bug that I couldn’t identify, the picture isn’t much clear, the insect was to fast to take a better pic.
I’m also sending you a pic of another bug that I never seen before, the picture quality is a little bit better.
hope you can help me out

Dear Charly,
The “chromatic bug” is a Leafhopper or Sharpshooter in the family Cicadellidae, and though we located a matching image on FlickR, it is not identified to the species level.  An image on American Insects is identified as being in the genus
Beirneola.  Your white winged insect is a Plume Moth in the family Pterophoridae.

Attached are pictures of a bug found on the stem and leaves of some flowers we just potted. I don’t know if they are good for the flowers or not and I have not seen it before. I also can’t seem to find anything online when I researched it. Please help!

Oak Treehopper

Oak Treehopper

Dear Amy,
Good and bad are so relative, and there are many extenuating circumstances when making such evaluations.  We generally think of problematic insects as those that are introduced from other locations if they are able to get established and have no natural predators, because they often crowd out native species.  This Oak Treehopper,
Platycotis vittata, is a species that we get frequent identification requests regarding, but those requests are almost always from Florida.  We thought this might be an introduction from a nursery, but upon researching the Oak Treehopper on BugGuide, we learned that it is found along the west coast of North America as well.  According to BugGuide:  “Forests and forest edges, parks, and anywhere Oak trees are found. Occasionally found on other trees, but these individuals were probably just resting on those non-Oak trees. … Does almost no damage to the host trees—leaves only a few twig scars from oviposition.”
