Common Atlantic Marginella snails were seen pulling clams from the Seagrass Meadow sand and eating them one by one. Their predation threatened the filter-feeder layer and raised the question of whether mud crabs might be needed again despite their own risks.

A grass skipper was added to the Lakeshore after moths appeared to do well in the lake. It quickly found a flower and began feeding, but within minutes it leapt into the black widow web and became a fresh nutrient transfer to the predator layer.

The original Southern Black Widow produced another hatch, but this brood was smaller than earlier waves. The smaller generation may reflect food scarcity or the female nearing the end of her egg production, while a male nearby suggested the next generation could continue the cycle.

Moths began appearing after wild Water Spangles were added to the Freshwater Lake. Instead of being wiped out by black widow webs, multiple moths persisted for weeks, raising the possibility that a flying-insect layer could move nutrients out of the water realm.

A cricket seen near the Lakeshore water edge was later caught high in a black widow web. The widow pulled the prey upward, showing that the Lakeshore widow population remained strong even as grassland widows declined and cricket numbers came under pressure.

A grizzled mantis and a larger green mantis were observed outside the system, but not introduced because miniBIOTA already had too much predator pressure. The record preserves the consideration point: mantises are fascinating, but even one could tip the balance in a small biosphere.

A young Hentz striped scorpion born in miniBIOTA became trapped in a Red House Spider web. Even after the scorpion struck with its tail and claws, the spider pinned the dangerous parts with silk, delivered a bite, and turned another predator into prey.

A Regal Jumping Spider was caught stalking and pouncing on a young black widow, confirming it as a major predator of the spiderlings in the Lowland Meadow. The black widows may still survive elsewhere, but the grassland group faced heavy hunting pressure.

A 3D-printed magnetic glass cleaner was built from sealed magnets, silicone, and hook-and-loop pads to clean viewing glass with less disruption. The first test dramatically improved visibility, starting a durability test for whether the tool can work long term.

Water Spangles were browning under lights that were too strong, so temporary XL4016 modules were added to reduce voltage on the fixtures. The adjustment aimed to keep the plants healthy until a new lighting system could be built, while crayfish grazing remained an ongoing pressure.

An Orangeclaw Hermit Crab repeatedly moved between the Lakeshore and coastal side, disturbing the black widow web corridor as it scavenged. By keeping that pathway from sealing shut, the crab helped insects continue moving between biomes and reduced the chance of one web cutting off traffic.

Slipper snails continued spreading across the Seagrass Meadow as stationary filter feeders with no obvious population ceiling. Tiny clams were added to the saltwater sand bed as potential competitors, creating a test of whether competition can slow the slipper snail boom.

A red house spider released a new generation of spiderlings, likely the grandbabies of the original spider introduced in March. With at least eight adults counted across the Mangrove Forest and coastal biomes, this entry marks the start of a possible stable red house spider lineage inside miniBIOTA.

Wild Water Spangles added to the Lakeshore brought both risk and opportunity. A predatory water bug appeared near vulnerable least killifish, while water fleas, scuds, larvae, and persistent Dollar Weed signaled a more active freshwater food web.

An Australian Cockroach matured in miniBIOTA, confirming three cockroach species in the ecosystem alongside Surinam cockroaches and Florida woods cockroaches. The roach layer turns dead leaves and other locked-up nutrients into soil, frass, and prey for the wider food web.

Black widow spiderlings spread into the Mangrove Forest and coastal side, but Red House Spiders already occupying those areas appeared to push their numbers back. The record frames a territorial contest between related cobweb spiders as widow waves keep arriving.

A week after Dollar Weed and Water Spangles were added, Dollar Weed kept sending out new growth despite grazing from crickets, crayfish, roaches, and snails. Water Spangles were hit harder by crayfish, so more were added to give the plant a better chance to establish.

Juvenile Hentz striped scorpions were seen under blacklight in the Mangrove Forest while adults were active in the Lakeshore. The sighting confirmed reproduction and established scorpions as another ground-level predator lineage inside miniBIOTA.

A fourth wave of Southern Black Widow spiderlings hatched from the original female tunnel and began spreading through the web network across all six biomes. With soldier flies declining, the spiderlings turned toward other prey such as young cockroaches as the population approached its system limit.

Black widow spiderlings caught a queen Common Crypt Ant during her nuptial flight. The ant nearly escaped by tearing through silk, but two spiderlings worked from opposite sides until she tired and became a shared meal.
