Dear bugman,
We found 2 caterpillars and brought them home, last weekend they both made cocoons. We’re wondering what kind of caterpillar they are. Any help would be appreciated.

Calleta Silkmoth Caterpillar

Dear Dani and Daniel,
This is the second red, green and blue Giant Silkmoth Caterpillar we are posting this morning, though the previous submission was from South Africa.  Your individual is the Calleta Silkmoth Caterpillar,
Eupackardia calletaBugGuide includes a long list of caterpillar host plants including:  “The primary Texas host is the ornamental shrub Texas Ranger Leucophyllum frutescens.”  BugGuide also indicates the flight time for the moth is from September to May, and we would expect that your moths will emerge when conditions are right after at least six weeks.  We would recommend keeping the cocoons in a sheltered location where they are exposed to outdoor temperatures as keeping them indoors may cause them to emerge when conditions are less than ideal.

Thank you so much for your help. We are so excited for the moths to emerge! They look lovely. Thank you again!

    We found this at Pierz Minnesota
    We didn’t think it was common

    We found six calleta silkworm caterpillars on our Texas sage, most in fifth instar with blue on the spikes. Beautiful!
