A passion vine butterfly lays her eggs

A passion vine butterfly lays an egg.
I watched this passion vine butterfly flitting around on a hedge, laying eggs atop the leaves of, you guessed it, a passion vine growing in the hedge. Typically, she deposits a single egg on each leaf, but this butterfly laid two on this one.

The butterfly is selective about which leaves to use. She chooses ones that have no eggs on them yet, since this will reduce the competition for her offspring. On the leaf she’s using in the photo are some yellow spots. I thought these might be where eggs had been laid previously, but some passion vines produce these colored bumps to make it look like eggs are already there and thus discourage the butterfly.

Not that laying eggs on unoccupied leaves guarantees survival. I saw a number of small parasitic wasps checking out the yellow bumps on several leaves. I have no doubt they do the same with the real eggs. I also saw a very small passion vine butterfly caterpillar snacking on what looked suspiciously like a newly-laid egg. And there’s always the possibility that someone will come along and trim the hedge. Not sure what the vine or the butterfly can do about that.

Sleepy orange butterfly

The sleepy orange butterfly (Abaeis nicippe) is one of the newest introductions to Hawaii. It was first seen on Oahu in December 2013 and is already established on all the main Hawaii islands, an unusually rapid spread. Part of its success in thriving here might be that has a wide range of habitats where it can live. It’s been spotted from sea level all the way up to 6,800 feet.

While its name is sleepy orange, like most of the butterflies I see here, it’s a rapid flier, jitterbugging around in such a way that it’s hard to capture in flight. Fortunately for me, this one was jitterbugging in 30 m.p.h. winds and seemed happy to take any opportunity to find a sheltered spot to rest.

The Hawaiian Blue butterfly (Udara blackburni) is also known as Blackburn’s Blue butterfly, Blackburn’s Little Blue butterfly, and the Koa butterfly. It is one of two butterflies that are endemic to Hawaii (the other is the Kamehameha butterfly). The caterpillars feed on Acacias, including Koa leaves, hence one of the names. It’s a small butterfly, only an inch or so long, but quite striking.

Secusio extensa – fireweed biocontrol moth

While out on a walk, I came across a patch of yarrow (Achillea millefolium) and thought the patterns made by the flowers would make a good photo. So I chose an individual plant to focus on and by good fortune found this moth hanging off the side.

The moth is Secusio extensa (I’ve also seen it referred to as Galtara extensa) and it hails from Madagascar. While this begins to smack of another invasive species, in fact this moth was deliberately introduced to the Hawaii in 2012. The reason for that is that the moth’s larvae feed on fireweed (Senecio madagascariensis) and fireweed is a truly bad invasive species here. Besides spreading in a prolific manner, it’s poisonous to livestock.

What I particularly liked about this individual was that it appeared to be enraptured by the yarrow plant, bobbing its head up and down continuously. I also loved its comb-like antennae, which are more properly known as pectinate antennae.
