We have a tenant in the new bat house 8.29.14

I am not sure how long it’s been there. A week or so ago I was watching it around dusk, 8pm, and spotted a bat that seemed to come from nowhere…but couldn’t be sure. It happened again a few nights later so now I am really watching.

Night before last I went out to the shop..set up a fan to keep the skeeters at bay….sat on a bucket and watched the bat house. Sure enough…out dropped a bat. At the time I couldn’t tell which chamber it came from.

The outer chamber is 7/8 “  to attract the Big Brown Bat and the inner chamber is 3/4” to accommodate the Little Brown Bat and the Freetails.

I took this picture from the video and you can just see the little guy leaving the outer chamber….Big Brown?

And away it goes….

I did see two flying around a few nights ago but was so happy to get this video I didn’t stick around to see if there were more. I’ll keep watch tonight.

The chamber it picked to roost in is away from our screen room. That is why I was sitting in the shop.

Short video but you can see it leaving.

We are thrilled!!! Did not really expect to have anything move in till spring…sure hope it stays and brings friends.

Gulf Fritillary caterpillars, chrysalis, pupating 8.28.14

6 of the caterpillars have gotten very big. Here’s one…it was about the same size as the one near the top when I brought it in.

009cs

You can see 5 of them here.

028cs

When they first shed their skins they are a light orange…the spikes a cream color and within a few hours they are as beautiful as these two.

040cs

3 of them went to the top yesterday and put themselves in the “J” formation…similar to the Monarchs and Queens.

You can see that it is losing some of it’s color…it is getting ready to pupate.

078cs

016cs

I had never seen the Gulf Fritillary pupate so it was pretty interesting. It does push it’s skin to the top and shake it off like the Monarchs, but there the similarity ends…

021cs

The video shows how it’s done. The other caterpillar is looking for a spot to do the same.

This is what it looked like a few hours later.

026cs

This is the next day…it is starting to angle itself, and will be almost parallel with the wood.

001cs

It’s a very interesting process , but can’t say I think these chrysalis are as pretty as the Monarch’s and Queen’s.

I read it takes about 8 days before the butterfly emerges. Can’t wait to see that!

Passion Flower Vine & Gulf Fritillary caterpillars 8.24.14

My friend, Debbie, gave me a small Passion Flower Vine. She has a big one growing on a trellis and this one popped up in her butterfly garden.

It was about a foot tall when I got it. Now it’s about 4 ft tall.

002cs

I also noticed there were caterpillars on it. Very pretty ones. Orange with black spikes.

005cs

I checked www.bugguide.com and the Passion Flower Vine is the larval plant for the Gulf Fritillary

016cs and the Zebra Longwing.  The Zebra Longwing caterpillars are white with black spikes. Hope to see a few of those too.

012cs

I noticed the wasps checking the plants for them so decided to go down the road and take some cuttings from a wild Passion Flower Vine and put them in a pot with rooting compound on them and bring the larger caterpillars into the Butterfly House. Here are 4 of the 7 I brought in.

018cs

025

By bringing them inside it will give the plant outside a chance to grow. There are already 6 little hatchlings on it and she was laying again today. Pretty little yellow eggs.

This one  is on the inside plant.

026cs

Their chrysalis is completely different than the Monarchs or Queens. Cant wait to see them.

We’re Going Batty!!! 8.5.14

At least we are trying to.

We’ve had 3 bats get aboard our boats. Two on the Albin Trawler, Slow Motion, and one on Meander, the boat we have now. I was able to catch one with a towel on the trawler and let it out and we guided one out. The one on Meander just kept flying back and forth in the boat until it found the open door and left on it’s own.

Little Brown Bats can eat  500 – 1000 mosquitos in an hour…imagine if they ate all night….and believe me….we have tons of mosquitos here.

The Big Brown Bat can eat hundreds of beetles a night. Hope they like hive beetles. They also eat wasps, flies, stinkbugs, dragonflies and flying ants.

I think both bats like moths…and wax moths can be a problem for a weak bee hive.

We went to the local hardware store and bought a bat house. Once home I did some research and that little house just wasn’t what they suggested for a good house…so we returned it.

I found some plans for a “Rocket” bat house. It will have less windage during hurricanes…and I liked the look.

Jim figured out what he needed for materials and got started.

Since we were using finished lumber instead of rough cut…he had to score all the boards that the bats would be using. This will fit over a 4x4. All the groves will give the bats something to cling to. The spacers are 3/4 of an inch. Small Brown Bats should fit in here comfortably.

010cs

Jim had to do every one of those scores with his skill saw. Table saw just wasn’t doing the job. Very time consuming.

012cs

016cs

The bats will be in that narrow space.

028cs

One box is longer than the other….that gives them a landing board. The next spacers were 7/8 of an inch so Big Brown Bats could fit. Not sure which we have flying overhead at night so trying to accommodate either.

Both sides of this had to be scored. He also put 4 cross over holes…2 (opposite sides) up high and 2 lower. (He forgot to take pictures so I drew them in)

033css

The outer box is on. The bats have 2 landing boards.

035cs

I was afraid the flat roof would be a good place for hawks to sit so Jim put some styrofoam on and made a peaked roof.038cs

I put a couple coats of water based stain on it…a medium color since we are in Florida and it should be in full sun all day. Jim put the black spots on so it would look like a bird house. When we got done I thought we should have put a clock on it instead…and had our own clock tower.

042cs

We sank 2 4x4s about 3’ in the ground and filled with concrete. There are 2 bolts in them. The top one will be for the pivot and the bottom to lock it in place. This will allow us to lower it in the future should it need work.

044cs

Guess it’s time to get it in the air.

The pole is made of 2 2x4’s screwed and bolted together. We did it that way because untreated was needed inside the house. Bats like temperatures up to 100*and treated can cause vapors.

The rope is so we can pull on it to raise the bat house.

046cs

The bat house is about 4’ long and weighs about 50 lbs. We set the pole on a short step ladder and put the house in place.

049cs

Jim pulled on the rope so I could put the taller ladder in place.

052cs

It was a struggle but we got it done. The loops in the rope are for me to stand in and Jim will go up the ladder and push it up as high as he can.

053cs

Once my weight brought the top loop to the ground Jim came over and together we got it raised. It had a bit of a “fishing pole” effect with even a light  breeze so Jim went back to Lowe’s and got 2 treated 16’ 2x4s …stained them and screwed them to the opposite sides. It really beefed it up.

057cs058cs

I like the look. It can still be lowered if necessary.

Now I check it each morning to see if there is any bat poop on the landing board or pole.

We may have gotten carried away a bit….but I sure do like it. Because we are surrounded by so many trees it really needed to be fairly tall.

I hope the bats move in and like it as much as we do. I sure hope I will be posting pictures of bats flying out before long. They do say that spring is the best time for them to find a home…but maybe somewhere nearby it’s getting crowded and a few need a new home.

Bats, Bees, Birds, Bob Cats, Butterflies….looks like we have all the vowels covered in the “B”s. Of course, we don’t see the Bob Cats as often as the others.

If you ever consider putting up a bat house…go to http://www.bathouseforum.org/forum/  and learn all you can. It is a great site. They can help with building plans or suggest where to buy one. Your bat house doesn’t have to be as big as ours but they can definitely help you get one that has a chance of being occupied.
