Here are a couple butterflies I met last spring, a Great Spangled Fritillary and a Hackberry Emperor . Both of them are midsized butterflies of 1 main color but with a lot of complicated patterns too. Despite these similarities, the mostly orange Great Spangled Fritillary and the mostly brown Hackberry Emperor are unlikely to be mistaken for 1 another, at least if you get a good look at them. (It might get more difficult if you throw the Variegated Fritillary and/or the Tawny Emperor into the mix.) I'm told that the proper way to address an emperor is "Your Imperial Majesty"; remember this if you run across a Hackberry Emperor. (I'm guessing you could address a Great Spangled Fritillary as "Your Greatness", though I could be wrong about that.)

A couple weeks ago while talking about a Hackberry Emperor butterfly, I wanted to post a link to my previous post about its relative, the Tawny Emperor . Unfortunately I didn't have one [1], so I'm going to remedy that on Throwback Thursday with a picture from 2.5 years ago. You probably shouldn't feel all that deprived of seeing the Tawny Emperor; it's quite similar to its Hackberry Emperor cousin. In contrast to the Hackberry Emperors I've seen, the Tawny Emperor's coloring is more of a brownish-orange (aka tawny) compared to the brownish-gray of many Hackberry Emperors. But this isn't the best way to ID them since apparently some Hackberry Emperors have the brighter coloring of the Tawnies; a better way is that if the top of the front wing contains 1-2 eyespots (something I talked about here ) then you've got a Hackberry Emperor. As wee little lads and lasses (aka caterpillars) both these emperors like to eat (surpringly): Hackberry Trees  [2]. As a...

What outranks a Monarch butterfly? Perhaps an emperor, like this Hackberry Emperor ? We don't see a lot of emperors around here, though this is the more common species of our emperors; I see its (similar-looking) Tawny Emperor even less. As you might expect given their name, the Hackberry Emperor uses hackberry trees like our local Common Hackberry  [1] as its host plants. (Their Tawny Emperor cousins also use these trees as hosts.) Unlike many native species, both emperor species appear to be increasing in numbers a bit. Presumably this means we have more hackberry trees than we used to; butterfly populations frequently correlate to the population of their host plants.

It seems like if you want to attract butterflies, you should get some Wild Bergamot ; here's yet another butterfly attracted to this wildflower: a Great Spangled Fritillary . These are one of my favorite butterflies. Their orange-and-black coloring and relatively large size make them easy to spot and fairly easy to identify. Probably the easiest butterfly (in my area) with which to mistake the Great Spangled Fritillary is the Aphrodite Fritillary , which has a black spot near the base of the forewing that the GSF lacks, and which is generally smaller. (My pictures don't show that spot, but the fritillaries I was seeing were almost the size of the Monarchs. I don't think an Aphrodite would ever get that large.) People sometimes see a Pearl Crescent and wonder if it's a baby GSF, but of course butterflies don't grow that way. They're pretty much at their full size when they emerge from their chrysalis. (I will admit that it's a little hard to see the pattern ...
