Your letter to the bugman:  Hello,
I found these caterpillars in my garden in Antigua Guatemala in July.
I made some research and it could be a Costa Rican hairy caterpillar (Automeris metzli ?) but I am not sure as Antigua is located at 1600 m in the mountains…
What do you think ?
Thank you !

Automeris Caterpillar

Dear Voiz,
We believe you have the genus
Automeris correct, but we are not certain of the species.  It looks to us like it might be Automeris boucardi, but we will check with Bill Oehlke to see if he can verify the species identity.

Luna Moth Caterpillar

Dear Dana and Laurie,
This is a Giant Silkmoth Caterpillar in the family Saturniidae, and based on this BugGuide image, we are nearly certain it is a pre-pupal Luna Moth Caterpillar.  This species often turns from green to orange as its time for pupation approaches.

Thank you so much for the information!  My 2nd graders just submitted an entry to the Ugly Bug Contest so I’m really paying attention to bugs right now.  I’ll share this experience with them so that they know that this is available to them.  Really appreciate your time!

Your letter to the bugma:  Hi – I Found a polyphemus caterpillar in the mail box(!?) and transferred it to an observation tank placed in a classroom.  I provided pin oak leaves and the caterpillar has spun a cocoon.  One website said the cocoon needs to over-winter in a cool place and will emerge in June.  Another website said it will emerge in a couple of weeks.  I would love for this marvelous creature to be able to survive and emerge  – any suggestions?
Thanks

Polyphemus Caterpillar

Dear Candace,
This is indeed a Polyphemus Moth Caterpillar.  Overwintering in a cool place is excellent advice, but the June emergence is probably information for a location with a cold winter.  According to BugGuide:  “In southern United States, adults fly April–May and July–August (2 broods); in northern part of range, adults fly from May to July (1 brood).”  BugGuide lists Washington sightings from April to October, which leads us to believe you may have two generations, so emergence might happen well before June, possibly even in several weeks.  We just located information that disputes that supposition, because according to Pacific Northwest Moths:  “Our populations are most likely single-brooded with capture dates from mid-April until August.  Second-brooded populations exist in areas with warmer climates.”  You might be able to witness eclosion in April.

Buckmoth Caterpillar

Dear Shane,
Though there are many spiny caterpillars in the Brush Footed Butterfly family Nymphalidae, we believe your caterpillar is a Buckmoth Caterpillar,
Hemileuca maia, based on this BugGuide image.

Imperial Moth Caterpillar

Dear LikesBugsNot,
The orange color on this Imperial Moth Caterpillar indicates it is pre-pupal, and it has left the tree or shrub upon which it was feeding in order to find an appropriate place to pupate.

Io Moth Caterpillar

Dear Katy,
This distinctive caterpillar is an Io Moth Caterpillar, and it should be handled with caution as it has stinging spines.  The adult Io moth is sexually dimorphic, with male Io Moths having yellow upper wings while those of the female Io Moth are brown.  Both sexes have pronounced eye-spots on the underwings that might help to startle predators.
