COMPARISON OF BEETLE DIVERSITY COLLECTED IN TWO STYLES OF DIY FLIGHT INTERCEPT TRAP Author: Katherine M. Arguez, School of Life Sciences, Arizona State University, Tempe, AZ, U.S.A. E-mail: karguez@asu.edu Kyle E. Schnepp, Florida State Collection of Arthropoda, Gainesville, FL, U.S.A. Email: Kyle.schnepp@freshfromflorida.com ABSTRACT Flight Intercept Traps (FITs) are a common, passive collecting technique in the field of entomology. Although effective, ready-made flight intercept traps can be cumbersome and costly. Here we compare two ‘self-made’ designs against each other, based on cost and a quantitative assessment of the diversity of Coleopteran specimens caught during a two-month period (May 5 to July 5, 2018) at the Archbold Biological Station in south-central Florida, U.S. Both the Hanging FIT and “V-FIT” (ISSN1937-8351) collecting surfaces are comprised of 2 mm Polyethylene sheeting. The Hanging FITs have a surface area of 8.325 sq. ft and were hung with their collecting vessels 3 feet from the ground. This trap design takes 90 minutes to construct with a field assembly time of 10 minutes; the total cost for one trap is less than $20. “V-FITs” are set on the ground with a height of 3.25 feet. The surface area is 16.25 sq. ft, construction takes 45 minutes, and field assembly time is approximately 30 minutes; total cost per trap is less than $50. A set of the two traps were placed ~ 4 feet apart at three random localities on "Red Hill", each representing a different habitat type: recently burned (27°11'01.5" N, 81°20'28.3" W), long since burned (27°11'02.6" N, 81°20'19.2" W), and mechanically mowed (27°11'05.4" N, 81°20'38.1" W). Throughout the two-month comparison we conducted five sampling periods. The project concluded with a total of 8,766 beetles identified within 53 families. Although less cost effective, the overall biomass and diversity found in the “V-FIT” surpasses that of the Hanging FIT and makes it the better candidate within the tested Florida sandhill/scrub habitat. DESCRIPTION OF PROTOTYPE DESIGN Hanging FIT This trap is designed to be hung within a wooded area anywhere in the canopy. Its purpose is to collect samples from areas usually inaccessible to other traps and/or difficult in terms of active collecting methods. The trap is designed to be easily taken apart and assembled in the field and can be stacked within one-another for easy storage.

The trap should be in a semi-wooded area to protect from wind and the trap should theoretically be able to run for upwards of 2-3 weeks without service. The body of the trap is composed of approximately 120in of 0.25in twisted nylon rope. The rope is looped through the 1in diameter PVC pipe cut to 30in, this is the top of the trap. Both ends of the rope are then looped through the two holes on the lateral margins of the “Zinsser 98030 30in wallpaper prep tray” and tied. This creates the rectangular frame of the FIT. Using the Dremel, make a small hole on either side of the top lip of the “Zinsser 98030 30in wallpaper prep tray,” approximately 1in. from the end of the trap where the rope is tied. Loop a pieces of the 13 gauge galvanized steel wire cut approximately 10in long in each hole and twist upwards to hold it in place using the needle nose pliers. Bend the top of each wire into a ‘hook-like’ shape and position ‘hook’ so that both are grasping the rope. Use the floral wire, cut approximately 5in long, to tie the two ‘hooks’ to the rope securely. Using the needle nose pliers, bend one end of the 13 gauge galvanized steel wire, cut approximately 16in long, into a loop so that is securely fastened above the knot of the rope under the lip on the “Zinsser 98030 30in wallpaper prep tray” rim; repeat on opposite side. Loop the opposite end of the 16in long wire several times on either end of the 1/2in rebar, 24in long. The rebar should hang laterally approximately 6in from the “Zinsser 98030 30in wallpaper prep tray.” Wrap the sheet of 2mm clear plastic cut to 30inx40in twice around the 1in diameter PVC pipe cut to 30in. Place the two large binder clips on either end of the PVC pipe, hold the plastic in place. Fold the edges of the plastic sheet around the rope making the frame of the trap and using the mini binder clips (approximately 8 on each side), secure the plastic in place; make sure the plastic is tight for the trap to work most efficiently. Take the 13 gauge galvanized steel wire, cut approximately 158in long, and bend into a rectangular shape (34inx44in) and loop ends together to close the rectangle. On top of the wooden board covered in a sheet of parchment paper, position said metal wire rectangle centered on the sheet of 2mm clear plastic cut to 38inx48in. Cut a 4inx4in square from each corner of the plastic sheet so that the inner most corner of each cut square is in contact with the wire metal square. Fold the excess plastic over the metal wire frame and place a second sheet of parchment paper over, hold securely. Using the clothes iron set on medium-low heat, gently melt the plastic fold to the plastic underneath. Make sure not to burn holes through. Repeat for all four sides. This is the rain cover. Once an area is chosen for the trap, determine how much rope is needed to secure the trap between two points (i.e. trees, pole, etc.). Loop the determined length of rope through the PVC pipe and securely fasten the trap between said two points. Carefully remove the large binder clips from the PVC pipe. Bend the rain cover on the 34in side in the center and place over the PVC pipe and secure in place with the original two large binder clips. Bend metal frame of rain cover to best shield the collecting tray from rain. Orient the trap on the rope in the best possible position so that it is as horizontal as possible. Using the two medium binder clips, clip the trap into place by clipping the binder clips securely to the rope so that the trap cannot slide. Pour enough ethylene glycol to cover base of tray to approximately 2-3cm. V-FIT: This trap is designed to catch low flying insects. It is made to be taken apart and assembled quickly in the field and to be compact for easy storage when disassembled. The trap is made to be able to go three weeks without service. Bulk Supplies Purchased For Making Of Traps: - Home Depot: HDX 10 ft. x 25 ft. Clear 3.5 mil Plastic Sheeting: $10.98: 5 traps - Amazon: DOBI ½ size Disposable Aluminum Foil Steam Table Deep Pans (30 Pack): 30 traps - Home Depot:Acorn International 2inx2ftx25ft Chicken Zaire: $22.99: 6 traps - Glycerin Supplier: Propylene Glycol 1 gallon(4 pack): $59.99: 8 traps LIMITING FACTORS EQUATE TO 5 COMPLETE TRAPS Each trap is comprised of: - Three 5ft poles of metal conduit ($8.85) - Two 10ft poles of metal conduit ($11.80) - 5ftx8.5ft sheet of 3.5mm plastic ($1.87) - Four 24in pieces of rebar - Four “1/2in. EMT/Rigid Pull Elbow” (90 degree angle elbow fixture) ($11.12) - 10 large binder clips ($3.33) - 4 x DOBI 1/2 size disposable aluminum foil steam table deep pans, 35 gauge aluminum ($0.64) - 1.5ftx5ft section of chicken wire ($2.76) - Propylene glycol ($7.50) TOTAL COST FOR EACH TRAP: $47.87 Extra supplies required: - Phillips head screwdriver - Conduit bender - Mallet - Saw/Trimmers - Vice - Hollow pipe large enough to for rebar Composition: Decide on an area for the trap. Using the saw/trimmers remove any debris or shrubs from selected area. Secure the rebar in the vice and slip exposed end into the length of hollow pipe 5-6in down. Bend downwards to create a hook. Repeat for all rebar pieces. Using the conduit bender, bend both section of 10ft metal conduit 3.3333ft from each end 90 degrees, making a metal “U.” Using the Philips head screwdriver, secure a “1/2in. EMT/Rigid Pull Elbow” to each end of the two results “U’s.” Connect the two “U’s” using the 5ft metal conduit poles; be certain that the elbows are securely fastened to the poles. This is the frame for the trap. Drape the 5ftx8.5ft sheet of 2mm plastic over the 5ft sections of the frame and fasten plastic on said frame with four large binder clips on either side of the trap. Place all four aluminum pans directly under the “V” created by the plastic in a centered, straight line across the interior of the trap. Cover the aluminum trays with the chicken wire and mold the chicken wire around the rim of the aluminum trays; verify that all the trays rims are overlapping to prevent loss of specimens through gaps. Place remain 5ft metal conduit pole on the plastic, this should emphasize the “V” shape. Alter the plastic as necessary so that the apex of the “V” is just above the trays, slight grazing the chicken wire. Once the plastic is at the correct length, clip the remaining two larger binder clips to the very edges of the pole on the plastic (be sure that the pole is centered over the aluminum trays) and remove metal attachments from clips. Using the gallon of 50/50 solution of water and Propylene glycol, fill all four trays evenly. Anchor the two ends of the trap with two bent rebar pieces using the mallet. METHODS Three locations on Red Hill were randomly selected, each demonstrating a specific habitat: - Recently burned (27.183749, -81.341185) - Long since burn (27.184057, -81.338672) - Mechanically mowed (27.184835, -81.343903) At each location a Hanging FIT and V-FIT were erected at approximately five feet from one another. Traps were serviced approximately every 2 weeks (weather allowing). Each traps catch was collected separately and labeled with the appropriate locality information. The duration of the project was March 5, 2018 – July 5, 2018. There were five sampling periods: May5-May20, 2018, May20-June2, 2018, June2-June12, 2018, June12-June17, 2018, June17-July5, 2018. Samples were then sorted to separate coleoptera from bycatch, coleopteran specimens then sorted to family. RESULTS Although less cost effective, the overall biomass and diversity found in the “V-FIT” surpasses that of the Hanging FIT and makes it the better candidate within the tested Florida sandhill/scrub habitat. These data were specific to the Florida scrub/sandhill habitat along the Lake Wales Ridge, therefore it is important to state that the outcomes of this project may not correspond other habitat type. Specifically if one is looking to study/collect canopy dwelling species, where the Hanging FIT would be most effective. FURTHER TRAP USES - Testing for hypothesized taxa is in the area, especially for specimens with flightless sexes, - Testing for taxa that fly in inclement whether, and - Testing multiple localities for long periods of time.

Inspired by the recently popular Keto ‘Chaffle’, this Keto Waffle has a crispy exterior, soft interior, and a sweet flavor. You’d NEVER guess these delicious waffles use only 5 ingredients and a blender to make! Crispy Keto Waffle Chaffle I’ve been seeing the famous ‘Chaffle’ recipe taking instagram by storm lately. If you’ve never heard of a chaffle, it’s basically a waffle made with just cheese and eggs! Sounds a little funky right, but people have been loving them. Yesterday, I needed a quick lunch but my fridge was pretty empty after returning from a vacation. So, I dug around and racked my brain. What did I have to work with? Pretty much just cheese and eggs. So, I gave in and decided it was time to try one of these famous chaffles for my self to see what ALL the fuss was about. My first chaffle was just shredded cheese and egg mixed together and cooked in the waffle maker, as everyone else does (typically in a mini waffle maker, but I used double the usual and a large waffle iron). I was NOT a fan. Don’t get me wrong here- because I LOVE LOVE LOVE cheese with eggs. But, the cheesy flavor with maple syrup? NOPE- not my thing. I like my waffles, non-cheese flavored if I’m having them with something sweet thank you very much. Not to mention, I am big texture person. Just using cheese and egg resulted in soggy, dense scrambled egg like interior with a bit of a melted cheese chew. The exteriors were extra crispy though. Which was super INTERESTING to me, since I can never get my keto waffles to have the crispiness on the outside that I used to love when I was non-keto (over a year and a half ago now!). Four rounds of keto waffles later, after messing with the cheese and egg ratios, plus adding a few other ingredients, resulted in what I thought was actually the BEST keto waffle I’ve ever had! The inside texture reminds me of a french cruller . Well, not exactly like it (I won’t really go that far), but kind of similar, and it looks a little bit like one too when you cut into it. Crispy Keto Waffle Chaffle Light and Airy Interior and A Crispy Exterior! Now, if you’ve never tried the ‘chaffle’ concept, don’t let the cheese in this recipe scare you away! I promise you can barely tell it’s there, especially if you use mozarella cheese as I did! I asked my husband to taste it before I told him what was in it and he had NO idea I had used cheese and just eggs as the main ingredients. Here’s what I did to completely change the texture and taste of the easy keto chaffle recipe. I believe EACH of these adjustments are VERY important to successfully make this. First, I added baking powder because I wanted little air pockets inside and a less dense middle. Next, I added sweetener, which for me was an erythritol (powdered) that would give it a sweetness without adding any carbs or spiking my blood sugar. Lastly, I added vanilla extract which I wasn’t sure would be good at first, but found that really helped cover up the taste of eggs and cheese in these! After all those additions, I tried putting them all into blender to mince the shredded cheese into smaller pieces and fluff the eggs up (without having to do ANY actual work at all ????) for 10-15 seconds. Crispy Keto Waffle Chaffle There is two more very important steps I found that were required to yield the best crispy Keto Waffle or ‘the chaffle’. First, the temperature and cook time makes a HUGE difference. Your waffle iron needs to be on the highest and hottest setting, and the cook time needs to be about 3 times longer than a standard flour waffle would be. In addition, you do NOT want to spray the waffle iron- it needs to be DRY. Both of these are how you get a dry and crispy exterior, but still a soft air pocket filled center. Now, I present you my new FAVORITE Easy and Crispy Keto Waffle Recipe – The ‘Chaffle’. The best part of it all is? It’s flourless, which means it’s super easy to make, I almost ALWAYS have the ingredients needed on hand already, AND it has the EASIEST clean up EVER (just wash the blender and clean the waffle iron!). Whenever we travel (which we usually always stay somewhere with a kitchen, I can make these for breakfast in a flash by just pre-packing the baking powder and erythritol, because the rest of the recipe uses ingredients from ANY grocery store! Keto Chaffles FOR THE WIN! P.S. My FAVORITE sugar-free Keto Friendly syrup to use on these waffles is hands down the CHOC ZERO syrups. They make fun flavors like MAPLE PECAN (which tastes like candy!), or Chocolate, Strawberry, and even Caramel!syrups! They’re only 1 g net carb per serving and have the BEST, thick and sticky texture of any keto syrup I have found! You can find them on Amazon (Here!). If you really want to step up your Chaffle game, you can make my SMOOTH Keto Salted Caramel in under 7 minutes to go with it! Add a little ice cream, or even whipped cream and you can enjoy these for dessert too ( let’s be real you can totally eat it this way for breakfast, because WHY NOT?). Or if you want to make Keto Chicken and Waffles, just make a few easy adjustments to this waffle recipe – omit the sweetener, and swap out the cheese with a more flavorful one like sharp cheddar ( or keep mozzarella either way will be delish!). Then whip up a batch of my KFC KETO FRIED CHICKEN with some chicken breasts and you’ll be in KETO chicken and Waffle HEAVEN. 🙂
