Questionmark Caterpillar

Dear Sandra,
When attempting to identify plant feeding insects, it is tremendously helpful to know the food plant.  Thanks for informing us this Caterpillar was feeding on hops.  We quickly identified it as the caterpillar of a Questionmark butterfly thanks to BugGuide.  Here is a BugGuide image that looks even more like your individual.  The adult Questionmark is a beautiful butterfly.

Your letter to the bugman:  Hello! Hope you are both well.
It was quite exciting to discover this little caterpillar attaching itself to a Kiowa Pecan sapling after a rainstorm. I’ve been getting photos of the chrysallis each day, and seeing amazing changes daily. We’ve had multiple thunderstorms and high wind (hence the staking of the sapling, not my preference but necessary on this hilltop). Temps 60-80 degrees, gusty winds, high humidity. Dates May 1, 2, and 3.
If I were to hazard a guess, I’d say this may be a Checkered White?
Thank you for all of your help. We live next to a green space now, lots of butterflies and birds… among other various living things 😉

Checkered White Caterpillar

Hi Ellen,
How nice to hear from you.  We apologize for the delay.  Daniel is currently in Ohio for Mother’s Day and there is excruciatingly slow internet here.  We agree with you that this is a Checkered White caterpillar (see BugGuide) and chrysalis (see BugGuide).  Perhaps you will be lucky enough to witness and photograph the eclosion of the adult butterfly.

Checkered White Chrysalis

Thank you so much! I’ll continue photographing and checking the chrysalis each day. It appears to be doing well despite the ongoing rain and wind. Best wishes, and safe journey to Daniel.

Your letter to the bugman:  Can you tell us what this is before we leave the state? Have lived in Florida for 17 years and have seen some strange bugs but this one takes the cake.
Thanks

Orange Dog

Dear Dennis,
This is the Caterpillar of a Giant Swallowtail, commonly called an Orange Dog because they feed on the leaves of orange trees and other citrus.

Your letter to the bugman:  Learn’d Fellows,
Every year at this time, my wild fig, having just sent forth it’s tremulous new leaves, is malevolently machete’d bare by these horned devil mowers. I have transplanted them to a wilder fig. Still I would  like to know my foe. Some deep-leaf sleeper-cells remain. Thanking you, in solidarity, ever-vigilantly.

Common Mapwing Caterpillars

Dear Castellano,
We believe these are butterfly caterpillars from the family Nymphalidae, and that is where we are going to begin our research.  Thanks for providing the host plant.  That is often extremely helpful, and that information quickly produced this FlickR image of a Common Map Butterfly Caterpillar,
Cyrestis thyodamas, and the poster wrote:  “The curious mind must ask, why is this caterpillar like this?  My observational response is that these larvae feed on the new leaves of Ficus trees. Developing shoots appear as tightly swirled red tips at the ends of branches and these caterpillars line themselves up along the axis of open leaves, heads closest to the origin of the leaf, with their spines imitating the fresh foliage that is developing.”  We like the name Common Mapwing which is used on Learn About Butterflies where it states:  “The Common Mapwing is usually encountered singly or in two’s and three’s, in open forest edge habitats. Males are often seen on gravel roads or along pebble-strewn river beaches, where they bask in full sunlight while imbibing mineralised moisture. They are initially nervous and difficult to approach but once they start imbibing they tend to remain at the same spot for several minutes.  Females are seen less often, but sometimes encountered along forest trails, or nectaring at flowers in forest gardens.  Both sexes habitually rest beneath leaves with their wings outspread.  Less commonly they will bask on the upper surface of large leaves, but tend to only do so in areas of dappled sunlight.”  This represents a new species for our site.

Sir,
Thank you for your gracious and comprehensive reply. I look forward to metamorphosis.
Their beauty is far from common.

In late December, Daniel noticed that the leaves on the wild mustard that was growing in the garden looked as though he had eaten them, but he knew he did not want to begin eating the leaves on such young plants.  When Daniel eats the mustard greens, he generally only picks half the leaf, leaving being the central vein and half a leaf to help the plant gain strength.  These Cabbage White Caterpillars seem to have adapted to eating only partial leaves to minimize the damage to the plant, though still rendering the organic leaves unappetizing to many picky eaters.  Here is a Cabbage White Caterpillar from BugGuide.
