Butterflies and other lepidoptera

Wild indigo duskywing skipper

This section is about lepidoptera in general — not just butterflies, but also skippers and moths. I’ve discovered that many species I had previously thought of as butterflies are actually moths or skippers.

For example, a few years ago, I might have thought this pretty little creature was a butterfly, but it’s a wild indigo duskywing skipper!

(And it’s not surprising that I found this skipper since I grow its host plant: wild indigo!)

What’s the difference between butterflies, moths, and skippers?

Here are some key differences — though as always there are exceptions!

ButterflyMothSkipper
BodyThin smoothThick furry
AntennaeSmooth with bulb or clubThread- or frond-likeLong thin with club tapering to pointed hooks at the tip
RestingWings fold over body so undersides are visibleWings fold down over body so wing tops are visibleFront wings held at different angle to back wings
TimeDuring day or eveningSome during day; some at nightDuring day
LarvaeGenerally spin a pad of silk then hang on pad and form pupaGenerally spin a cocoonGenerally spin a pad of silk then hang on the pad and form pupa

Unfortunately, the popular book The Very Hungry Caterpillar contains some basic inaccuracies about butterflies:

  • They eat junk food.
  • They eat any green leaf.
  • They build a cocoon.

(Moths create cocoons, but not butterflies.)

Butterfly myths

We have to provide habitat for all stages of a butterfly’s life cycle!

Here’s how we provide habitat for these insects:

We have a separate section for monarchs since they have unique conservation issues and especially capture people’s interest.

Our lepidoptera

Here’s a list of all the lepidoptera (butterflies, moths, and skippers) that have visited our yard.

But we’ll never see some butterflies …

I won’t find this zebra swallowtail in my yard (though as the climate changes, who knows?)

When I first started learning about butterflies, trying to identify the species, I’d just leaf through books trying to find a match.

But then I realized that most species can be eliminated if you look at their range. No matter how much a butterfly I’m trying to identify in my yard looks somewhat like a butterfly that lives only in California, for example, it’s not likely to be that one.

This is true for selecting larval host plants, too. When I first started habitat gardening, I just looked at lists of larval host plants without considering whether butterflies that use those plants might ever visit my yard. Now I make sure the larval host plants I choose have a good chance of being used.

It’s not hard: Plants native to our region will likely be a good match for lepidoptera native to our region.

Reflections

Diversity of species is a form of safety in numbers — not numbers of individuals, but numbers of ways in which each individual’s prodigious reproductive power is modulated by conflicts of interest among all the individuals with which it shares the land. The more species there are, the less likely it is that any one of them will get out of hand and — just as true — the less likely that any one of them will suffer unduly.
