I’m an observer of nature which is how I learn things. Sometimes nature can throw a curve ball. Through my kitchen window I spotted a Zebra Swallowtail Butterfly nectaring at the Bidens alba just off my patio. Being a favorite butterfly of mine I grabbed my trusty Nikon point and shoot from the dining table and headed out to try to stealthily creep up to get a photo of this beauty in constant motion for my “Central Florida Critter of the Day” blog. I got a few shots and was satisfied I probably had a good one to share.
Since I only write about what happens in my own yard, I learned a long time ago to not use a SD card in my camera because I’d never get back in the house if I had unlimited shot capacity at hand. I allow myself the 20 or so high quality photos that can be captured on the camera’s internal memory. That way I get back inside within a reasonable amount of time, am not overwhelmed with too many photos or choices and I don’t get a sunburn. I also rarely go back inside without full capacity on the camera being used…I believe in efficiency and there is ALWAYS something of interest to be photographed in nature. It is a habit that has served me well…although it can be a bit frustrating at times to get that “memory full” message when an amazing creature is in front of you. Still, there is a delete button to make room for a once in a lifetime shot.
At any rate, I glanced up and saw a Gulf Fritillary Butterfly (Agraulis vanillae) fluttering over where the Florida native Maypop Vine chose to pop up this year. I figured I’d finish off my photos over there. That’s when I noticed that she laid an egg on the blackberry stem hidden within the maypop. I took a photo as she fluttered beneath my hands.
I got another shot of her actually hitting the intended maypop target with an egg. I was in the middle of taking a photo of a planthopper when I noticed Miss Frit had laid an egg on a single silk strand of a web of the resident Long-jawed Orb Weaver Spider (Leucauge argyra). The butterfly continued to flutter around when I saw her lay an egg on some Sida rhombifolia. That’s when she fluttered so close to me that I swear she was trying to lay an egg on ME. This butterfly had gone rogue…laying everywhere. Even the Bidens alba was “egged”.
So, what did I learn?
- Not all butterflies have good aim;
- Just because a butterfly lays an egg on a plant doesn’t necessarily mean it is a host plant;
- The adage “Close only counts in horseshoes (and hand grenades)” needs to add “and butterfly egg laying”
There were plenty of visitors stopping by including a dragonfly, a few wasps, ants and others that I’m sure won’t care which buffet the eggs are on.
Addendum: came across a research study which indicates there may just be a method to their madness: “Egg-laying patterns in butterflies in relation to their phenology and the visual apparency and abundance of their host plants”
