Bugs Abound

Bugs abound in the Back Woods this summer! If you are a fan of most things Arthropoda, you might want to spend and afternoon hitting the trails, scouring the foliage, and sifting through the leaf litter in the Back Woods.

Nectaring butterflies have been the hot commodity at the Buttonbush Pond during the spring/summer bloom. The egg laying action is about to pick up in the sandhill where the partridge pea (Chamaecrista fasciculata) will prove irresistible to a variety of sulphur butterflies. The sandhill is where you will also find our very own example of Sisyphus in the rainbow scarab (Phanaeus vindex) diligently rolling up and and storing whatever piles of poo it comes across. Florida harvester ants (Pogonomyrmex badius), forever on the march, find their home in the sandhill as well.

The cicadas are most definitely turning up the volume through out the woods…look for their molts at the top of shrubs and dead  branches. Keep your focus ahead on the trails lest you walk right into the web of a tiny spiny orb weaver (Gasteracantha cancriformis) or a not so tiny golden silk spider (Nephila clavipes). One of my favorites, the green lynx spider (Peucetia viridans), looks like green glass. They don't spin a web but rather stalk the foliage for their unsuspecting prey.

Deep in the leaf litter you will likely come across all sorts of things including the real Florida palmetto bug…the Florida woods cockroach (Eurycotis floridana). These nearly wingless roaches are not considered household pests preferring the rich bounty of the outdoors to your pantry. Disturb them and they emit a very noticeable odor something like almonds or sweet amaretto.

Once you have had your buggy fill of the Back Woods don’t forget to stop off in the Bioworks Butterfly Garden for an up close look at the metamorphosis of Florida native butterflies.

Of course, the woods would not be the woods without our very own population of mosquitoes. So, use good sense as you would in any outdoor area this time of year, cover up and wear your insect repellant.

Song of the Cicada

DSCN0021

The cast nymphal skeleton of a cicada clasped tightly to a branch of silkgrass (Pityopsis graminifolia). After four years underground and four molts, this was the last nymphal instar of the cicada. From this molt they emerge the winged adults that fill the summer nights with song.

If you are originally from up ‘north a ways’ you may remember the cicadas of your childhood summers varying from year to year. Northeastern populations of some cicada species are periodical and may appear in mass numbers in 13 to 17 year cycles. In Florida, populations of adults are produced every year.

Cicadas nymphs and adults both feed on plant fluids but neither is considered a serious pest in Florida. On the the other hand, adult cicada are considered good eating by numerous wildlife and are considered a notable survival food for humans as well. Hmmmm.
