The hardest bugs to catch on Animal Crossing are the tarantula and the scorpian. they both run along the ground so fast and the scorpian also stings you. the best way to catch a scorpian is to not chase it with your net out! creep SLOWLY up behind it without your net, and when it doesn't move, then get your net out. then QUICKLY catch it!
