What Butterfly House & Aquarium Inc does
Mission
Inspiring conservation of the vital building blocks of sea, sky, and land.
As stated on its FY2022 Form 990.
Program
The butterfly house & aquarium had 40,546 visitors during the july 1 - december 31, 2022, timeframe. Opportunities to experience tropical ecosystems are minimal to nonexistent for most residents in the landlocked, all-season midwest. A reprieve from the cold, encounters with colorful butterflies and fish, and the tranquility of the exhibits establish our facility as a one-of-a-kind destination in the dakotas. With over 800 tropical butterflies in a year round 80-degree oasis, and twelve saltwater aquariums, we strive to leave an impact on every guest through interactive learning and healing experiences with nature. In addition, free admission is provided to various social service nonprofit partners to provide the opportunity to heal and relax year round surrounded by beautiful butterflies and aquariums. Throughout the july 1 - december 31, 2022, timeframe, 132 volunteers gave 2,784 hours of their time.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $3.6M to $0 (−100%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 0% · 2021 15%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 6 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base held at 4 funders, grant income fell $92k → $81k.
4 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 90% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of BUTTERFLY HOUSE & AQUARIUM INC’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
BUTTERFLY HOUSE & AQUARIUM INC leans on a few funders — its largest provides 86% of grant income and the top three 95%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
95% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund BUTTERFLY HOUSE & AQUARIUM INC.
Largest funder’s share by year: 2017 73% · 2018 71% · 2019 98% · 2020 78% · 2021 56% · 2022 60% · 2023 68% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
25% of BUTTERFLY HOUSE & AQUARIUM INC's funders are still giving 3 years after their first grant; 58% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
90% of BUTTERFLY HOUSE & AQUARIUM INC's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $174k that is directly attributable, 97% of it comes from South Dakota funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.5M arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
