You are correct that the timing is more consistent with coddler.  (We have not yet got any 
coddling moth here in Zone 5a, but will in another few weeks).  But to distinguish EAS from 
coddling moth you really need to count their legs - other than the EAS having two more sets 
of legs the two larvae look essentially identical.  (The EAS is yellowish-white, and the coddler 
is pinkish-white, but without a comparison this is subtle.)  The frass from the EAS is 
malodorous and from the coddler odorless - the problem here is that I, (and I suspect, many 
other males), cannot smell the EAS frass in the first place.  (Get a woman to sniff it if need 
be.) (Totally off-topic, but did you know that a woman can pick out her baby by smell alone 
within 24 hours of birth?)
