Hi – Found this in Southern Arizona and I think it is eating my pecan trees. Not sure what it might be, but hoped you might be able to help. Sure is an interesting looking creature. Thanks for looking!

Pipevine Swallowtail Caterpillars

Dear Steven,
These are Pipevine Swallowtail Caterpillars, and they will eventually metamorphose into beautiful butterflies.  To the best of our knowledge, they do not feed on the leaves of pecan trees, but rather, on pipevine, according to BugGuide.  Perhaps you have pipevine growning amongst your pecan trees.

Subject: Beetle in the grass with Chinch bugs – fend or foe to the lawn?

I know we have a Chinch Bug problem in the grass ; but I also have lots of these in the same areas of the Chinch bugs. They look close to Cosmopepla lintneriana – Twice-stabbed Stink Bug, but not quite. Or maybe some kind of small Ladybird?
They are varying sizes, but very small. This is a close-up of one of the larger ones I placed on my arm.
Location is costal Sothern California. Season is late summer (1st week of September) Are these fend or foe to the lawn?

After a long search, I just figured out that the images I sent in were African Painted Bug nymphs and are a foe to the lawn and all my other garden plants.

Immature African Painted Bug

Dear Steve,
We are pleased to hear that you were able to self identify this immature African Painted Bug,
Bagrada hilaris, a small Stink Bug that was recently introduced to Southern California and is quickly spreading.  They are usually associated with plants in the cabbage family including wild mustard that grows in southern California fields.

A friend found two of these caterpillars crossing her driveway. The lawn it crossed is very large and bordered by woods. It reminds me of a Tomato Hornworm but the spots are very different and it does not have the diagonal stripes. It is 2.5 inches in length.

White Lined Sphinx Caterpillar

Dear MEP,
Late summer and early autumn caterpillar sightings are very common because the caterpillars have reached their full size and often leave the plants upon which they were feeding to seek appropriate places for pupation.  You caterpillar is that of the highly variable White Lined Sphinx, and it is in the same family as the Tomato Hornworm.  White Lined Sphinx caterpillars range in color from black through orange and yellow to green.  Your individual is greener than we usually see.

Greetings – Have just happened onto your page in process of trying to identify what turned out to be a Hag Moth larvae which dropped onto my hand today. Will doubtless be back – very useful sight – especially for nat’l science junkies.
I will attach a screen shot of the top left area of your home page which is somehow missing some of the text to tell us what we need to click on to reach the ’Ask WTB’ and ’Bug Love’ linked pages. (Have worked on websites – not a techie, but writer/editor and pay attention to such stuff.) Thought I’d share the info in case you hadn’t seen it. Thanks…

Monkey Slug

Hi Sue,
We are happy you were able to identify your Hag Moth Caterpillar, commonly called a Monkey Slug, thanks to our website.  As a side note, we accidentally hit the “t” instead of the “g” when naming the Monkey Slug and we needed to correct that error prior to posting since we try our best to maintain a G rated website.  Thanks for bringing the homepage problem to our attention.  We will copy our crack webmaster on this matter to see if he can get to the root of the matter.  We just checked it out on our Safari and Firefox browsers and it is fine.

Subject: Invasion of Orange Ants

Sept 1 2012, Young’s Point Ont. N. of Peterborough Ont. I beleive a member has recently posted the same insect This happens each year to the date. Weather is always humid with the grass cool and not in sun light. It will last all day into evening. It seems a mass of these ants coming up from the ground. There is also what I will call Gnats, I am not sure if I am correct on this but many of them. They inter-act with the ants. This area is around our septic system. Our grounds are mostly rock and half clay to sandy earth. We have had little rain as with most folks. It is just amazing to see as I said you can put your time to this happening.

Swarming Cornfield Ants

Hi Donna,
Since posting the photo that your first commented upon, we have learned that these are swarming Cornfield Ants or Citronella Ants in the genus
Lasius.  The Cornfield Ants are sexually dimorphic with males being black and females red.  The winged ants are the Alates or reproductive males and females.  A mated female will become the queen of a new colony.  The red ants without the wings are the sterile female workers.  The seasonal appearance makes sense for a mature colony that will produce new Alates each year and they will swarm when weather conditions are right.

I have read a few of the comments concerning the mysterious spiders apparently covered with a white frosty-looking substance. I have seen these in Maine, and am cleaning a few pictures of them off of my desktop. The ones I saw were definitely dead, as I could touch them with a stick with no reaction.

Fungus-Ridden Spider

Hi Andrew,
Thank you for your first-hand observations and photographs of this Fungus-Ridden Spider phenomenon.  One of our most frequently commented upon postings has sparked a debate on whether these spiders are dead or alive.  We maintain it is a fungus infection and it is possible that some of the spiders might not have completely expired, but they are not long for this world.  We believe the fungus might attack the spiders while alive, but death shortly follows.
