Short notice -- afternoon bioblitz at Ladd Nature Preserve in Duncanville! Thursday, Nov 16, 2-5 pm!

Hey all!

A bit of a short notice announcement, but we're planning on a bioblitz/biosurvey next week Thursday (Nov 16) at Ladd Nature Preserve in Duncanville. Two of the new urban wildlife biologists from Austin and San Antonio are coming up, and we're wanting to show them how we conduct and participate in a biosurvey. They're relatively new to iNat as well, so some of it will be just showing how to use the tool.

If you're able to come, cool! It is during somewhat odd hours -- 2 to 5 PM on Thursday... I fully recognize that it won't work for everyone, but if you've got some time free and watch to come and catch some bugs or look at plants or chase after birds with us, please come!

Also, it looks like it may be rainy -- we'll still plan on doing it in the rain (bring boots and umbrella)! :)

If you have any questions or concerns, let me know. It's open to anyone and everyone!

Important video to watch RE: iNaturalist!

So, if you've got a free 20 min or so, you really need to watch @kueda 's commencement keynote about iNaturalist:

I'm sure happy to be in this community with so many of my friends -- some I've met in person, others I've met just online -- but we all share that enjoyment by engaging with nature. :)

10 years on iNaturalist!

I joined iNaturalist on 21 September 2013 -- was introduced to it by Derek Broman @dbroman , then the urban wildlife biologist in Dallas/Fort Worth with Texas Parks and Wildlife. Since then, it's radically changed the way that I go outside and how I engage with nature.

So proud and happy and lucky to be a part of this growing and vibrant community of nature enthusiasts!

Charles F. Ladd Nature Preserve! Celebration!

42 acres in Duncanville are being preserved -- this is a wonderful thing!

So, what now? Well, we naturalists need to continue to go out to the land, tell our friends, tell strangers, go out to this place and continue to engage with nature! So far, around 1000 species have been documented (, but there are countless more out there to engage with.

If you find yourself out there, be sure to bring a little bag for any trash that you see! @mgram55 and many others have dedicated a LOT of time and energy to not just this advocacy for the land, but also the daily trash removal. It's a good thing to help out with this as we can!

I predict more developments coming out of all of this (trails, foundation of a 'friends' group, bioblitzes, other nature events), so I'll be posting updates as I hear them! In the meantime, celebrate this good news!!! :)

My black-light set up!

So, in preparation of National Moth Week, I want to update some folks about my black-lighting set up! Now, I still use some of the equipment from BioQuip (unfortunately, they went out of business), but I've also been using some new gear.

Mercury vapor bulb - super power! So, this does not run on any of my batteries, this only works via an outlet. This mercury vapor I got from BioQuip, so I don't know where you could get one... I put it on a tripod rather than hang it up. It tends to be a bit too powerful, to be honest -- it's kinda painful on my eyes, even when I'm not even looking at it! It brings in LOTS though, so I still use it from time to time.

BioQuip UV lights - these are the circular lights -- I was fortunate enough to purchase 5 of these, and so far, they still work! I wish wish wish I knew where one could still get these, but alas, I can't seem to find them anywhere...
I have a few different batteries to run these-- I have a Yeti 1000X and then two Yeti 200X:
The batteries are a bit pricey, but they are pretty long lasting.

New lights -- so I've found that the relatively cheap UV lights are pretty good! There are a lot of options for these, but the flat black-lights powered by USB have been quite productive:
I think that the main characteristic needed is the spectrum of 385-400nm...
I use portable chargers to run these:
I'll also use some USB extension cords so that I can hang these lights from one of the taller branches:

I did also just purchase a new black-light from This was fairly pricey, and I've not yet gotten it, so we'll see how it functions!

As for sheets, I use the fairly cheap white bed sheets. The ones that are fairly consistent in thread count/pattern are the most useful, I think. These are usually around 10 bucks.

To hang the sheets, I use a bunch of clothes pins and try to place them on branches/trees/shrubs so they stay put... Now, if there's some wind, that stinks for the photography and for the moths to stay still on the sheets... The more still the conditions, the better!

One of the things that my good friend @k8thegr8 got me was magnets! I use these magnets to secure a few sheets on the sides of my vehicle. I then hang up the BioQuip UV lights close to these sheets.

As always, I tend to see the most biodiversity in areas with good wildlife habitat (diversity of plants), and if there is relatively little light pollution.

  • BioBlitz/biosurvey at Ladd Natural Area in Duncanville
    Duncanville City Council has been deciding on what to do with this 42 acres along Ten Mile Creek, so the more evidence we can show that it's a refuge for biodiversity and the naturalists that engage with it, the better! I hope you can come!

CANCELLED Friday, April 28 - 8 to late

Saturday, April 29 - 3 - 6 and then 8 to late (for blacklighting!)

Monday, May 15 - 3 - 8 pm

  • Pollinator bioblitz at Canyon Creek Wetlands in Richardson
    Super cool site with some really active master naturalist activity, but not a lot of insect observations -- we're planning a bioblitz to focus on the pollinators on this date. It's come and go, so stay as long as you'd like!
    parking spot is at Hilton Garden Inn Dallas/Richardson, 1001 W President George Bush Hwy, Richardson, TX 75080

Insect Appreciation Workshop - Saturday, Dec 3, 9 am - 3 pm! All about bugs. :)

Super excited about a workshop that's coming up in a few weeks... This will be all about the joys of bugs!!! Some really good friends and active iNatters will be presenting on the joys of moths, bees, beetles, dragonflies, and flies! It's going to be in person at North Lake College in Dallas, but it's also going to be available to watch online. Would love to see you in person or online to learn along with me!
(all proceeds go to the North Texas Master Naturalists)

Big thanks to @brentano @kimberlietx @kimberlywalks and @entomike for presenting on insects this day.

Also, MASSIVE thanks to @laurahaynes for doing a super human job of logistical planning.

Bugs are cool. :)
