A water treader attacked a cricket nymph that fell onto the water surface, then another water treader displaced it and took over the meal. The observation showed that even the freshwater surface had become an active predator zone.

A third generation of collared ground crickets appeared as a larger field cricket generation entered the food web. The record frames a coming competition between two omnivorous cricket groups that convert overlooked nutrients into prey for higher-level predators.

The Southern Black Widow second egg sac hatched into a prepared web network, letting spiderlings fan across the Lakeshore and into the Lowland Meadow. A Regal Jumping Spider began hunting them, but many spiderlings still reached the grassland and started building webs.

The next engineering focus shifted to rebuilding atmosphere heat exchangers and connecting the chiller. Those systems would let miniBIOTA regulate upper and lower tank temperatures, drive weather, and eventually control seasonal conditions across the biosphere.

After three weeks without a confirmed meal, the black widow caught and fed on the katydid that had been added two weeks earlier. She consumed the legs, clipped away the web around the body, and dropped the empty husk, leaving the remaining nutrients to cycle back into the soil through other organisms.

Apple snails and Malaysian trumpet snails were added to the Freshwater Lake to disturb a stable Ludwigia-dominated system. The goal was to increase grazing, stir the substrate, release trapped nutrients, and push the lake into a more dynamic stage.

After five years of development, miniBIOTA was moved to a new home where the system could expand further. The move required removing atmospheres, lights, and connected modules while minimizing disturbance to the living habitats. This entry records a logistical and strategic turning point: miniBIOTA leaving its old room, surviving a complex relocation, and preparing for a larger public-facing phase with species data tracked on miniBIOTA.com.

The first wave of black widow spiderlings appeared to be gone, leaving only old webbing behind. A nearby Regal Jumping Spider had been hunting in the same area, making predation a likely explanation, while the mother black widow still carried another egg sac.

Another Atlantic Sand Fiddler Crab released abundant zoea into the Seagrass Meadow water column. Unlike the earlier spawn, this attempt happened after wave movement and temperature control were in place, giving the larvae a better chance to persist.

A large cricket crossed into the coastal marine side and used its ovipositor to lay eggs deep in the beach sand near a fiddler crab tunnel. The observation raised an open question about whether cricket eggs could hatch in the salty shoreline environment.

Night observation showed a Hentz striped scorpion feeding on a small cricket, confirming that the new predator was catching prey in miniBIOTA. A UV check also revealed the second scorpion nearby, suggesting both individuals were active and surviving after introduction.

A second Hentz striped scorpion was found in the house and added to miniBIOTA, where the first scorpion was already active. The size difference raised the possibility of a male-female pair, which could help regulate the expanding cricket population if both survived.

A Regal Jumping Spider found on the house was added to miniBIOTA even though predator pressure was already a concern. The spider immediately disappeared into the brush, entering a large habitat with springtails, isopods, and young roaches as possible prey.

The first wave of black widow spiderlings had already thinned and moved upward, likely under heavy competition and disturbance from larger insects. Meanwhile, the mother carried a new egg sac, setting up another wave even if most of the first generation failed.

A UV flashlight finally revealed the Hentz striped scorpion that had been missing since its introduction to the Mangrove Forest. The scorpion fluoresced clearly under the light, appeared to be feeding well, and could now be tracked more reliably inside the biome.

A second-generation red house spider in the Marine Shore captured a two-lined spittlebug much larger than itself. The spider ignored the prey's defensive liquid, wrapped it, delivered a fatal bite, and pulled it into the web corner, showing that the red house spider lineage had become an active predator in the coastal biome.

Two ant species that had coexisted in miniBIOTA for years surfaced after extra water was added to offset evaporation. Ghost ants and a likely Hypoponera or Ponera-type crypt ant both moved around to stay dry, turning the watering event into an identification and behavior check.

The introduced Southern Black Widow egg sac hatched, spreading tiny spiderlings through the biosphere. Most were expected to die through competition, predation, or dispersal, but the hatch transformed the question from one predator to a possible population-level shift.

The Southern Black Widow did not settle in the expected mangrove corner. Instead, she built in the dark corridor between the Lakeshore and Lowland Meadow, turning a major crossing route into a web trap for crickets and other travelers.

A large female Southern Black Widow found under the grill was captured with her egg sac and introduced to miniBIOTA. The transfer marked the start of a major predator experiment, with the spider settling into the brush after being released from the container.
