Care Guide for Platymeris biguttatus (Two-Spot Assassin Bug)
Introduction
Platymeris biguttatus, commonly known as the two-spot assassin bug, is a fascinating predatory insect native to sub-Saharan Africa. Renowned for its striking appearance and predatory prowess, this species has become popular among insect enthusiasts. Despite its appeal, P. biguttatus requires careful handling due to its venomous bite, which can cause pain and localized swelling in humans. This guide provides detailed information on how to care for and maintain these captivating creatures in captivity.
Housing
Enclosure
The enclosure for P. biguttatus should mimic its natural environment while ensuring safety and ease of maintenance. A suitable terrarium setup is essential:
Size: A 10-gallon (20x10x12 inch) glass or plastic enclosure is sufficient for a small group of 3-5 individuals. For single specimens, a smaller container, such as a 5-gallon tank, will suffice.
Ventilation: Proper airflow is crucial to prevent mold and maintain a healthy environment. Use mesh lids or side vents.
Material: Glass or plastic enclosures are recommended for easy cleaning and observation. Ensure that the enclosure is escape-proof.
Substrate
Provide a substrate that retains moisture but does not become waterlogged:
Options: Coconut fiber, peat moss, or a mix of topsoil and sand.
Depth: 2-3 inches to allow for hiding and burrowing.
Maintenance: Spot-clean regularly and replace entirely every 2-3 months or as needed.
Decor
Enhance the enclosure with elements that replicate the bug's natural habitat:
Hiding Spots: Cork bark, egg cartons, or small tubes.
Climbing Structures: Branches and twigs for vertical exploration.
Plants: Add fake or live plants to provide additional hiding places and visual appeal.
Temperature and Humidity
P. biguttatus thrives in warm and moderately humid conditions:
Temperature: Maintain a range of 75-85°F (24-29°C) using a heat mat or lamp if necessary.
Humidity: Keep humidity levels between 50-70%. Mist the enclosure lightly every few days, but avoid over-saturating the substrate.
Monitoring: Use thermometers and hygrometers to track temperature and humidity levels.
Feeding
P. biguttatus is a voracious predator, feeding primarily on live prey:
Diet
Primary Food: Crickets, roaches, and other feeder insects of appropriate size.
Occasional Treats: Waxworms, mealworms, and small caterpillars.
Size: Prey should be no larger than the bug’s body length to avoid injury.
Feeding Tips
Remove uneaten prey within 24 hours to prevent stress or injury to the bugs.
Observe the feeding process to ensure all individuals are eating. Separate aggressive feeders if necessary.
Water
Provide water in a shallow dish with small stones or sponges to prevent drowning. Mist the enclosure lightly to maintain humidity, and ensure there is always a water source available.
Behavior
P. biguttatus is a nocturnal and predatory species with fascinating behaviors:
Activity: Active at night, hiding during the day.
Social Structure: Can be kept communally if provided with sufficient space and resources, but monitor for aggression.
Defense Mechanisms: They can spray venom or bite if threatened. Handle with care and avoid unnecessary disturbance.
Handling and Safety
P. biguttatus is not a handling pet due to its venomous bite:
Avoid Handling: Use tools like tweezers or soft brushes to move them.
Protective Gear: Wear gloves if direct contact is necessary.
First Aid: If bitten, wash the area with soap and water and apply a cold compress to reduce swelling. Seek medical attention if severe symptoms occur.
Breeding
P. biguttatus can be bred in captivity with the right conditions:
Mating
Conditions: Provide ample hiding spots and slightly increase humidity to encourage mating.
Observation: Mating involves the male mounting the female; this can last several hours.
Egg Laying
Substrate: Females lay eggs in the substrate. Ensure it is moist but not waterlogged.
Frequency: Females lay clutches of eggs every few weeks.
Incubation
Duration: Eggs typically hatch in 6-8 weeks, depending on temperature.
Care: Do not disturb the substrate; transfer eggs to a separate container if needed.
Nymph Care
Housing: Keep nymphs in a smaller enclosure with a moist substrate and adequate ventilation.
Feeding: Offer smaller prey items such as pinhead crickets or fruit flies.
Growth: Nymphs molt multiple times before reaching adulthood. Ensure proper humidity during molting periods.
Health and Maintenance
Common Issues
Mold: Prevent by maintaining proper ventilation and avoiding overwatering the substrate.
Pests: Remove uneaten prey promptly to prevent mites or other infestations.
Dehydration: Ensure humidity levels are adequate and provide a water source.
Cleaning
Spot-clean the enclosure weekly, removing waste and uneaten food.
Perform a deep clean every 2-3 months, replacing the substrate and disinfecting the enclosure and decor.
